1. IntroductionAdenocalymma Mart. ex Meisn., orth. cons. (McNeill et

al., 2006), is a Neotropical genus, and one of the mostspecies-rich (47 species) genera of the tribe Bignonieae.It is distributed from Mexico to northern Argentina(Udulutsch et al., 2009). In Brazil, where 42 (89%) outof 47 species occur,Adenocalymmais widely distributed,being found in 25 out of 26 states, and is represented inall vegetational types, including rain forests, seasonalsemideciduous forests, and savanna formations(Udulutsch et al., 2009).

Te name Adenocalymma is o Greek origin, whereaden, adenos (masculine noun = gland) and kalymma

(neutral noun = cover or calyx) reer to pateliorm glandspresent on the calyx o most species. Te generic namewas proposed by Martius in an annotation made on aspecimen in 1839, but was validly published only 1 yearlater by Meisner (1840a: 300; 1840b: 208).

Although in the original publications (Meisner, 1840a,1840b) the orthography or the genus was Adenocalymna(with mn), in the index o Meisners work (published in1843, part 2, p. 374, Meisner, 18371844) and some laterpublications, e.g., Bentham (1876), the orthography orthe genus was Adenocalymma (with mm). Bureau (1872)showed that the orthography used in the protologue, and

then later by de Candolle (1845), was incorrect and alsodid not fit the origin o the term kalymma.

Although Bureau (1872) corrected the originalorthography or Adenocalymma (with double m, a

change officially allowed by the ICBN; see article 60,McNeill et al., 2006), many authors have used the nameAdenocalymna (with mn), both in articles (e.g., Smith,1893; Moore, 1895; Krnzlin, 1915; Rusby, 1920; Standley,1929; Gentry, 1993) and on herbarium labels (e.g., Rusby,Schumann, Standley). More recently, Scudeller (2000b),based on the discussion presented by Bureau (1872) andthe actual history o the use o generic names, proposedthe conservation o Adenocalymma (with double m),which was approved by the Committee or Spermatophyta(Brummitt, 2001) and is listed in Appendix III o the ICBN

(McNeill et al., 2006).Until the previous century, the last review to includeAdenocalymma was the treatment o Bignoniaceae inFlora Brasiliensisby Bureau and Schumann (18961897).Tereafer, species descriptions have been published inisolation (description o new species) or in local floras.

In a recent revision o Adenocalymma, Udulutsch(2008) ound 144 names that have been proposed or thegenus, o which 47 were correct and accepted, 75 wereconsidered synonyms (29 under Adenocalymma speciesand 46 under other Bignoniaceae genera), 14 were not

validly published (6 were nomina nuda and 8 appeared

on herbarium labels only), and 8 were considered asinsertae sedis. Tis study resulted in several nomenclatural

Abstract:A recent taxonomic treatment oAdenocalymmaresulted in nomenclatural changes associated with 47 names and 24 species.Seven emendations, 16 new synonyms, 29 typifications (24 o which are lectotypifications), 4 neotypifications,1 epitypification, and1 status change are proposed. Emendations are related primarily to the first description o the ruit o Adenocalymma dichilum, A.divaricatum, A. fruticosum, A. hypostictum, A. macrophyllum, A. salmoneum, and A. scabriusculum. A variety o Adenocalymma, A.marginatumvar. apterospermum, has been raised to the rank o species (A. apterospermum).

2.1. New synonyms, typifications, and emendations

Sixteen new synonyms, 29 typifications (24lectotypifications, 4 neotypifications, and 1 epitypification),and 7 emendations o a total o 47 names associated with 24species o Adenocalymmaare given herein. Emendationsrelate to the first description o the ruit o 7 species(Adenocalymma dichilum A.H.Gentry, A. divaricatumMiers,A. fruticosumA.H.Gentry,A. hypostictumBureau &

New synonym:Gentry (1982) cites in the protologue

o Adenocalymma sousae that this species can bedistinguished romA. apurenseexclusively by the presenceo larger capsules and wingless seeds; however,A. apurensealso has wingless seeds. Tis conusion began when Gentry(1973b) synonymised under A. apurense all the speciespresenting the leay connective, namely A. calderonii(Standl.) Seibert, A. grenadense, A. hintonii Sandwith,and A. inundatum Mart. ex DC., without taking intoaccount several morphological differences among thesespecies (exceptA. hintonii, which should be considered asynonym oA. calderonii, andA. grenadense, considered asynonym oA. apurense). Since ruits were known only or

A. calderonii, and these had winged seeds, this characterwas automatically conveyed to A. apurense. In a recent

revision o the genus (Udulutsch, 2008), these specieswere clearly distinguished, and one o the main eaturesthat differentiated A. apurense rom A. calderonii wasthe presence o wingless seeds in the ormer and wingedseeds in the latter. Tus, we considerA. sousae, which has

the same circumscription and geographic distribution(Mexico to northern South America) as A. apurense, as ataxonomic synonym o this species.

Typification: For the nameAdenocalymma grenadensewe have ound only 4 isotypes, deposited at C, L, NY, and P.As the holotype (originally deposited at B) was destroyedduring World War II (Hiepko, 1987), we selected one o theisotypes as lectotype, this being the specimen deposited atNY, which is the only ertile one.

Tus, we consideredA. macrostachyumassynonym oA. bracteatum.

Typification:For the name Bignonia bracteatawe haveound 2 isotypes deposited at E and K. As the holotype(originally deposited at B) was destroyed, one o theseisotypes had to be chosen as lectotype. Since the specimendeposited at K has well-developed inflorescences andwhole open flowers, it was selected as lectotype.

New synonyms:In 1957, Sandwith had already noticedthe similarities between Adenocalymma purpurascensand A. bracteolatum, leaving the ollowing note on theholotype o A. purpurascens: Neither A. impressum nor

A. inundatum, but certainlyAdenocalymma bracteolatumDC. Subsequently, in 1977, Gentry made another note onthe same specimen, indicating that these species could bedistinguished rom one another by the presence o wingedruits in A. purpurascens. However, this is an inaccuratenote, since until 1977 there were no ruit collectionsidentified asA. bracteolatum, which makes the comparison

invalid. Currently, collections are known with flowersand ruits, which were unidentified in herbaria, and allhave yellow-rust coloured scales in the inflorescencesand winged ruits and seeds, the characters used torecognise the species. Tus, afer a careul analysis o thetype specimens, protologue, and existing collections, weconsiderA. purpurascensas synonym oA. bracteolatum.

Anemopaegma huachianum Rusby was reducedby Gentry (1977) to the synonymy o Adenocalymma

purpurascens. However, as both Anemopaegmahuachianum and Adenocalymma purpurascens fit within

the circumscription oAdenocalymma bracteolatum, theyare being synonymised under the latter.Typification: Te holotype o Adenocalymma

bracteolatum was originally deposited at P; however, asthere are 4 specimens at P, a lectotypification is necessary.Among the 4 sheets, the only one with the name onthe label made by de Candolle is P00468570, which wedesignated here as lectotype.

Observation:Moore (1895) published 2 species basedon 2 different specimens (Adenocalymma croceum basedon BM 000992347 and Anemopaegma decorum S.Moorebased on BM 000992352, both rom the same locality),but cited only one collector number (980) or both othem. However, the holotype o Adenocalymma croceumhas the number 950 and also a later-added label withthe number 980, whereas the holotype o Anemopaegmadecorumhas the number 980. Tereore, we have opted orassociating the collector number 950 with the holotype o

Adenocalymma croceum(as it is on the original label).4.Adenocalymma bullatumBureau ex K.Schum., Nat.

Typification: Te protologue o Adenocalymmabullatum includes no cited specimens. However, at alater date, the author (along with Bureau, Bureau, andSchumann, 1896) cited a single known collection used todescribe the species (Glaziou 7771), which thereore is the

original material. As there are 7 specimens o Glaziou 7771deposited in 5 herbaria, a lectotypification is necessary.Among the 7 materials, 2 (deposited in P) have notes madeby Bureau on the label suggesting the epithet bullatum,but as only P00594794 is ertile, we selected it as thelectotype.

Typification: Sandwith, when describingAdenocalymma hintonii, selected 2 specimens as typematerial (typus floris and typus ructus), which,according to the Code o Botanical Nomenclature (McNeill

et al., 2006, art. 9.4), are considered syntypes. O thesesyntypes the flowering specimen (Hinton 3784) was chosenas lectotype, because the ruiting material (Hinton 7259)has no leaves. Additionally, the diagnostic characters (e.g.,leay connective and corolla lacking nectaries) are presentin the K material, reinorcing this choice o lectotype.Although the vast majority o the specimens collected byHinton can be ound in NY, number 3784 (selected hereas lectotype) was ound only in BM, K, and MO, withouta duplicate in NY.

Although Gentry had treated A. calderonii as a

synonym o A. apurense (Gentry, 1973a) and then o A.inundatum(Gentry, 1976; 1982),A. calderoniican easily bedifferentiated rom all other species with leay connective(A. apurenseand A. inundatum) by its winged seeds andcorolla lacking nectaries.

New synonyms: Tis is a species with greatmorphological variation in its vegetative organs, notallowing separation o the varieties proposed by Bureau

(1894) and Bureau and Schumann (1896). Te extremevariants are detected when collections rom areasoccupied by restinga vegetation are compared with thoserom the Atlantic Forest. Tis variation is continuousand it is thereore not possible to suggest any diagnosticcharacters or these taxa. Tus, Adenocalymma comosum

var. acutissimum, A. comosum var. lanceolatum, and A.comosum var. nitidum are considered synonyms o A.comosum.

Typifications: Te original material o Bignoniacomosa is composed by only 3 specimens: the holotype,

originally deposited at B, and 2 isotypes, deposited at Kand NY. As the holotype was destroyed during World WarII (Hiepko, 1987) one o these isotypes had to be chosenas lectotype. Since the specimen deposited at K has well-developed inflorescences and whole open flowers, it wasselected as lectotype. Te material deposited at NY hasonly one broken inflorescence and a ew buds.

Bignonia acutissimawas known only rom its holotype(Brazil, So Paulo, Serra de Santos, s.a. (fl), F. Sellows s.n.),which was originally deposited at B, and rom photographso the same specimen deposited at F and K. As thespecimen was destroyed and we did not find other material

or illustration associated with the protologue, a neotypewas chosen. Tis choice took into account both the local

collection o original material as well as the diagnosticcharacteristics presented in the protologue. Tus, amongthe specimens collected in the Serra de Santos, the onethat best fits the description in the protologue is Chiea590, deposited at SP, which was selected as neotype. Te

main morphological characteristics that made this choicepossible, i.e. they were present both in the protologue (andphotograph o the holotype) and the neotype selected, werelanceolate to elliptical, long and acuminate, discolouredleaflets, and second-order bracteoles larger than the calyx.

In the protologue o A. nitidum5 syntypes are listed:Bacl [303, G00133589], Gaudichaud-Beaupr [s.n.,G00133605], Lhotsky [22, G00133617], and 2 collectionsbyMartius(39, deposited at M and with a duplicate at thesame herbarium, and s.n., not located). O these syntypescited by de Candolle, only one o them (Martius 39,

M0086336) has well developed inflorescence. Moreover,this is the only one with the name on the label and notesmade by Martius (including a detailed description), andits characteristics perectly fit the description given in theprotologue. Tereore, this specimen is designated here aslectotype.

For the last new synonym proposed or this species,Adenocalymma comosum var. lanceolatum, there is alist o 8 collections (syntypes) used or the description.O these 8 syntypes, Martius 244, deposited at BR, E,G, K, MO, and NY, does not fit the circumscription o

A. comosum, because, among other characteristics, it

has axillary shoot prophylls and calyx lacking nectaries(in A. comosum the prophylls are woody and the calyxhas nectaries). Tis collection, Martius 244, fits thedescription o Adenocalymma ubatubenseAssis & Semir,a species recently described (Assis and Semir, 1999). Othe remaining syntypes, 2 were probably destroyed asthey were at B (Widgren s.n., collected in Rio de Janeiro- Rio de Janeiro State, and Wied-Neuwied s.n., collectedin Ilhus - Bahia State), and we have ound no duplicatesat other herbaria. Te 5 other syntypes were collectedby Glaziou, and o these only 2 (Glaziou 4126 and 4722)

have the original identification made by Bureau on thelabel. O these 2 collections, only Glaziou 4126 is ertileand perectly fits the description o the material presentedin the protologue. O the 2 specimens o Glaziou 4126,the specimen deposited at P [P00594790]was selected aslectotype because it was probably analysed by Bureau andSchumann (annotations by Bureau have been made on thelabel), whereas the sample deposited at R has no originalannotations on the label.

New synonym:Adenocalymma salzmanniihas the samediagnostic eatures as A. coriaceum such as corolla withnectaries, included stamens, olive-brown inflorescence,glabrous leaflets and, mainly, inflorescences that developin old stems, with a large diameter, a characteristic thatdoes not occur in any other species o the genus. Tus,afer analysis o the protologue and type material, we herepropose the synonymisation o A. salzmannii under A.coriaceum.

Te names A. coriaceum and A. salzmannii werepublished in the same paper, but as the epithet coriaceumis used more requently in herbaria and publications, wechose to maintain its use. Since this was the first choicebetween 2 names o equal priority level (McNeill et al.,2006, art. 11.5), priority o the name A. coriaceum isestablished here.

Unlike other species o Adenocalymma publishedin Prodromus Systematis Naturalis Regni Vegetabilis (deCandolle, 1845), the authorship oA. coriaceum, accordingto comments at the end o the description, is A.DC. andnot DC. because Alphonse de Candolle was the one whoexamined the material and described the species.

Typifications: Bignonia cymbalum was describedrom a single collection (F. Sellow 1613) and most likelyrom a single specimen, because duplicates were notlocated. Since the specimen, originally deposited at B, wasdestroyed and there is no illustration or other materialassociated with the protologue, it was necessary to choosea neotype. Since there is no precise indication o thelocation o the holotype collection, this parameter couldnot be used to guide the choice. Tus, in addition to the

diagnostic characteristics presented in the protologue, wechose to consider the specimens examined in taxonomic

studies that included the holotype o B. cymbalum, that is,specimens that were analysed and described along with thespecimen collected by Sellow. Te only study that used theholotype o B. cymbalumtogether with another collectionon which to base a description was conducted by Bureau

and Schumann (1896) or Flora Brasiliensis. In this work, inaddition to the collection by Sellow, a specimen collectedby Pohl is also cited, and it is designated here as theneotype. Afer analysis o the specimen collected by Pohl,deposited at BR, and comparisons with the descriptiongiven in the protologue and with a photograph (at F andK) o the holotype (at B, but destroyed), it is clear that thespecimen selected as neotype has the same characteristicsas the original material.

Te holotype o ecoma fulgenshas parts that belongto more than one taxon, as already discussed by Sandwith(1958) ecoma sp. (pro maxima parte) and Memora

fulgens (pro minima parte), and most o the descriptionconducted by Martius and presented by de Candolle (1845)reers toMemora fulgens. Tus, we designate it here as thelectotype, retaining the name to that part that correspondsmost nearly with the original description (McNeill et al.,2006, art. 9.12).

As the type o de Candolles name consists o morethan one species, and Memora fulgensis the pro minimaparte, we selected an epitype (McNeill et al., 2006, art. 9.7).

Additionally, althoughA. divaricatumoccurs in the Stateo Minas Gerais (as doesA. magnoalatum) no comparison

between these species was made in the protologue o A.magnoalatum (Scudeller, 2000a). Tus, we consider A.magnoalatuma taxonomic synonym oA. divaricatum.

Te variety described by Bureau, A. bracteatum var.macradenum, also fits within the circumscription o A.

divaricatum, as it has the same diagnostic characteristicso this species, such as prophylls lacking nectaries andwith parallelodromous veins, second order bracteolessymmetric, corolla lacking nectaries, calyx internallypapillose, and ovary glabrous. Tus, we consider A.bracteatumvar. macradenumas synonym oA. divaricatum.

Adenocalymma fruticosum was described rom asingle collection and was thought to be a shrub due tothe absence o tendrils (hence the epithet ruticosum).However, this species was recollected recently in thearea near the type locality and all individuals ound had

tendrils, characterising its habit as lianescent.13. Adenocalymma grandifolium Mart. ex DC. inA.DC., Prodr. 9: 199 (1845), nom. nov.

New synonyms: Tis species was first described in1829 as Bignonia grandifolia by Vellozo (1825 [1829]).However, this name is a later homonym or B. grandifoliaJacq. (Jacquin, 1798) (Anemopaegma grandifolium(Jacq.)Merr. & Sandwith), and is thereore illegitimate (McNeillet al., 2006, art. 53). Tus, de Candolle (1845) published

Adenocalymma grandifoliumas a new name or Bignonia

grandifoliumVell., and both have the same type (McNeillet al., 2006, art. 7.3).Adenocalymma prasinum was created by Miers

(1861) as a declared substitute (new name) or BignoniagrandifoliaVell. However, de Candolle (1845) had alreadydone this 16 years beore (A. grandifoliumMart. ex DC.).Tus, A. prasinum Miers is superfluous and illegitimate,and must be rejected (McNeill et al. 2006, art. 52.1).

Te variety proposed by Laroche (1973),A. grandifoliumvar. guilleminii (and its basionym A. guilleminii) isconsidered a synonym o Adenocalymma grandifolium.Te diagnostic character used by Laroche (1973) cannot

be used to differentiate between the proposed variety andthe type-variety. Te only character used as diagnostic or

recognising the different varieties was the width o theleaflets, but when comparing specimens collected alongan altitudinal gradient, the differences between the leafletswere continuous. Additionally, the type o these namesalls within the variation accepted orA. grandifolium.

A second name as a new synonym orAdenocalymmagrandifolium is A. pleiadenium, whose holotype isindistinguishable rom the holotype o A. guilleminii,which is also synonymised under Adenocalymma

grandifolium(see above). Te holotypes o A. guilleminiiand A. pleiadenium come rom the same location (theSerra dos Orgos, State o Rio de Janeiro, Brazil); however,Bureau and Schumann (1896) did not have access to theholotype oA. guilleminii, a act that may have contributedto the description oA. pleiadeniumas a new species.

Contrary to what was proposed by Laroche (1973), andcited by Gentry (1975),A. macrophyllumis not a synonymo Adenocalymma grandifolium. Tese species can easilybe distinguished by, among other characteristics, theposition o the stamens (inclusive in A. macrophyllum,against exserted in Adenocalymma grandifolium) and theindumentum o the leaflets (with dendritic trichomesin A. macrophyllum, against glabrous in Adenocalymma

grandifolium).Typifications: Te variety described by Bureau and

Schumann (1896), Adenocalymma grandifolium var.iodocalyx, is associated with a single collection, however,we ound 5 duplicates rom this collection; 4 are deposited

at P and 1 at R. aking into account the sheets at P, 2were annotated by Bureau, rom which we selected thespecimen P00594797 as lectotype, since it is ertile, haswell-developed inflorescence and flowers, and is in goodcondition, besides being in perect agreement with theprotologue.

Te holotype o Adenocalymma pleiadenium wasprobably lost, as we have not ound any original material.Even the P herbarium, where most type specimens o thespecies described by Bureau and Schumann are deposited,has no type specimen. As the only duplicate ound is at

R, we designate here this sheet as the lectotype, althoughthere is no indication that Bureau and Schumann saw it.14. Adenocalymma hypostictumBureau & K.Schum.,

Bang 1321has flowers (the diagnostic characteristicso the species are floral), and several duplicates distributedat E, G, K, M, MO, and NY herbaria. Since importanttypes o Rusby were originally deposited at NY (Stafleuand Cowan, 1981) and only NY00579086has annotationsmade by Rusby himsel, indicating the proposed new

name, this specimen was designated as lectotype.Te original material o Adenocalymma sclerophyllumcomprises a single collection (Ule 5496) and 2 specimensdeposited at B and MG. As the holotype deposited at Bwas destroyed, we selected as lectotype the only isotype weound (deposited at MG).

In the protologue o A. auristellaethe only collectionindicated as type is Ule 9779. As the holotype depositedat B was destroyed, it was necessary to choose a lectotyperom among the isotypes, which are deposited at MG andK. Te specimen deposited at K was designated as lectotypebecause the dimensions o both leaves and flowers agree

ully with those in the protologue. Te dimensions o thespecimen deposited at MG are slightly smaller.

Lectotype (designated here): Suriname, Marowijne:1854 (fl), Wullschlaegel11 (BR00880320!), syn. nov.

New synonym: Gentry (1976), in his studies inpreparation or Te Flora of Venezuela, reinterpretedthe Adenocalymma apurense complex based on thecharacteristics o ruits and reconsidered A. inundatumand its variety A. inundatum var. surinamense, bothsynonymised previously under A. apurense (Gentry,1973b). However, conusion still abounded as he statedin this study (Gentry, 1976) that A. inundatumcould becharacterised by winged seeds, whereas A. apurense and

A. inundatum var. surinamense had wingless seeds. Weanalysed collections containing flowers and ruits o A.inundatum(both varieties) and confirm that the seeds inthis species do not have wings in any o the varieties. Tus,the synonymisation o A. inundatum var. surinamenseunderA. inundatumis proposed, since the only differencecited or distinguishing between these taxa was thepresence or absence o wings in the seeds.

Typifications: Adenocalymma inundatum was

described rom a single collection, which consists o 3specimens deposited at M. Since there is no indicationthat these specimens are parts o a single specimen, theyshould be considered duplicates (McNeill et al., 2006, art.8.3). Because onlyM0086326among the 3 specimens citedhas well-developed inflorescence and flowers, we selectedit as the lectotype.

In the protologue o Adenocalymma inundatum var.surinamense2 syntypes were cited, Wullschlaegel 11 andHostmann & Kappler s.n.Since the collection Hostmann& Kappler s.n.has probably been lost (not ound in any

herbaria), we selected Wullschlaegels collection, whosespecimen is deposited at BR, as the lectotype.17. Adenocalymma macrophyllum (Cham.) DC. in

(1845), Adenocalymma marginatumvar. polystachyum, isconsidered a synonym o A. marginatum.Te diagnosticcharacteristics used by the author (e.g., smaller petiolulesand slightly larger calyx) cannot be used to differentiate

between the proposed variety and the type-variety,because when comparing specimens the type o this namealls within the variation accepted orA. marginatum.

Typifications: Te holotype o Adenocalymmamarginatum, a specimen collected by Sellow that wasdeposited at B, was destroyed. Since it was cited as a singlespecimen in the protologue o this species (which did nothave duplicates), it is necessary to choose a neotype asnomenclatural type. Te collection Gaudichaud-Beaupr560 is the only one cited in the work o de Candolle (1845),which together with the specimen collected by Sellow, was

used as the basis or the description o A. marginatum.Tus, we selected Gaudichaud-Beaupr 560, deposited atG-DC, as neotype. Additionally, this choice is reinorcedby the act that the description given by de Candolle (1845)fits the description in the protologue.

Te variety described or this species (A. marginatumvar.polystachyum) was based on 2 collections rom Bahia,one collected by Blanchet and deposited at G-DC and theother collected by Martius, which has not been located.O these syntypes, the collection deposited at GD-C isannotated by de Candolle (1845), and we thereore selectedit as the lectotype.

Typification:Te species Adenocalymma paulistarumis ound in the literature spelled 2 different ways: as A.

paulistarum(with r, in most studies) and asA. paulistanum(with n, as on the labels o the collection Mllo 28and inhis manuscript, published posthumously; Mllo, 1952).

Mllo, collector o the original material, used tosend his collections o Bignoniaceae to Bureau (who bythen was already an expert on this amily) and in one othese consignments Mllo sent a probable new specieso Adenocalymma (Mllo 28) without suggesting a nameor it. In 1869, in a response to Mllo, Bureau gave thechosen name or the species (A. paulistanum), whichwas accepted by Mllo in his manuscripts (Mllo, 1952).However, some years later, when the species was effectively

published (Schumann, 18941895), Schumann called itA. paulistarum, which is grammatically correct, being aplural genitive o paulista, and this name was used in allsubsequent works.

In the original publication o A. paulistarum there isno indication o the type material; however, in a later study(Bureau and Schumann, 1896), the author o the speciesin partnership with Bureau published a more detaileddescription and indicated 3 collections, Regnell III 902,

Mllo 28,and Sellow s.n.,but the third o these, originallydeposited at B, was destroyed.

Considering that the specific epithet is paulistarumand that the only collection rom the State o So Paulo is

Mllo 28(as noted by Mllo [1952], this very collection wasthe original material used by Schumann), this collectionwas thereore used or choosing the lectotype. However,as the collectionMllo 28is represented by 4 specimens, 2deposited at K, 1 at S, and 1 at US, o which only the first2 (K) have notes made by Bureau on the label, suggestingthe specific epithet, and that there was no indication thatthey are parts o a single specimen, these preparations areconsidered duplicates (McNeill et al., 2006, art. 8.3) and wechose the specimen with flowers and ruit as the lectotype

Adenocalymma subsessilifoliumDC. var. tephrinocalyx(Bureau ex K.Schum.) R.C.Laroche, Loegrenia 56: 8(1973), syn. nov.

New synonym: Te shrubby habit o Adenocalymmatephrinocalyx is shared by only a ew species o thegenus; however, the sessile leaves and unnel-shapedcorolla distinguish this species rom all others except A.subsessilifolium. Te absence o nectaries on the corollaand the greyish indumentum on the inflorescence o

A. tephrinocalyx easily differentiate this species rom A.subsessilifolium (nectaries present on the corolla and theerruginous indumentum on the inflorescence).

Based on the morphological characteristics mentionedabove, the treatment by Laroche (1973), who consideredthis species a variety oA. subsessilifolium, is inappropriate.

Typification: In the protologue o this species thematerial used or its description was not mentioned;however, later the same author, in partnership with Bureau(Bureau and Schumann, 1896), cited 2 collections (Glaziou

8815 and 9527), the only ones known or this species todate.

At P there are 2 specimens o Glaziou 8815, and one othem is mounted on a sheet together with a portion (singleinflorescence) rom Glaziou 9527, a separate collection othe same species. Tis sheet bears 2 separate barcodes, eachcorresponding to the parts o these different collections:

Glaziou 9527 [P00594805]and Glaziou 8815 [P00594806].Tus, the only complete collection (includingvegetative and reproductive parts) o the species is Glaziou8815, used or lectotypification. We ound 3 specimens othis collection, 2 o which are deposited at P and the otherat R; those at P were used or the original description othe species because there are notes made by Bureau onthe labels suggesting the name tephrinocalyx. O these 2specimens, we selected P00594807as the lectotype becauseit contains only Glaziou 8815in the preparation, avoidingany urther conusion.

New synonyms: Tis is one o the ew species oAdenocalymma described in the work o Vellozo (1825[1829]), which has been accepted, although the originaldescription is extremely brie. Te citation o the corollanectaries as a diagnostic characteristic o the species and

its occurrence recorded or Rio de Janeiro are importantor sufficient identification o the species.Afer examination o the protologue o A.

longiracemosum var. trichocladum, it was clear that thistaxon alls within the circumscription o A. trifoliatum,eaturing, among other characteristics, nectaries onthe corolla and the same geographical distribution.Tus, the variety A. longiracemosum var. trichocladumis now considered a synonym o this species, includingthe combination made by Laroche (A. trifoliatum var.trichocladum), since the diagnostic character used by theauthor (quantity o indumentum on the leaves - abaxial

surace o leaflets, petiole, and petiolule tomentose) cannotbe used to differentiate between the proposed variety and

the type-variety, because when comparing specimensthe quantity o indumentum is very variable (we oundspecimens rom hirsute to glabrous). Additionally, thetype o this name alls within the variation accepted orA.trifoliatum.

Typifications: Te variety Adenocalymmalongiracemosum var. trichocladum was described rom asingle collection,Martius 1080, which is currently knownonly rom 2 photographs, deposited at K and F. Since noother material associated with the original protologueexists, neotypification is necessary.

Te varieties proposed by de Candolle (1845) can bedifferentiated, according to the author himsel, only bythe large amount o hirsute indumentum on the stemsand leaves o A. longiracemosum var. trichocladum. Aferexamination o various collections, a continuous variationo this characteristic was observed, i.e. rom glabrous tohirsute plants, not allowing the recognition o varieties,which led to synonymisations (see New Synonyms itemabove). Tus, the choice o a neotype orA. longiracemosum

var. trichocladawas based on the amount o trichomes othe specimens and, consequently, in their agreement withthe protologue. Tus, we selected the specimen Araujo7133, deposited at GUA, as neotype because it is one othe specimens that best represents this extreme variation(large amount o hirsute indumentum on the stems andleaves).

Typifications: In the protologue o Adenocalymmauleanum, Krnzlin (1915) cited only 2 collections, Ule6280 and Ule 9784, which were deposited at MG and B,

respectively. As there was no indication o the holotype inthe protologue, it is necessary to choose a lectotype romamong these syntypes. Since the collection deposited at Bwas destroyed (only 2 photographs are currently knownand deposited at F and K), we selected the specimen Ule6280, deposited at MG, as the lectotype.

Adenocalymma latifoliumwas described rom a singlecollection, Bang 2535, which has 3 specimens, 2 depositedat NY and another at K. As the specimens at NY areprobably original, since Rusby worked at NY (Stafleu andCowan, 1981) and there are notes made by Rusby on thelabels o these specimens, we selected the preparationNY00313041, which has well-developed inflorescencesand flowers and a young ruit, as the lectotype.

ype: Brazil, Santa Catarina: Florianpolis, avaresriver, 11 Mar 1953 (fl, r), Reitz & Klein 300 (holotype:K000449343!).

Adenocalymma apterospermum was described as avariety o A. marginatum and, according to the author(Sandwith, 1955), it is different rom the type varietybecause it has less compressed valves, wingless seeds, andleaves with an apiculate or emarginate apex.

However, the presence o leaflets with a retuse andmucronulate, rarely obtuse apex in A. marginatum var.apterospermum (against acuminate apex inA. marginatum

var. marginatum), cylindrical ruits with a length towidth ratio o 2.74.6 and a thickness o 3 cm (againstsubcylindrical ruit, with a ratio o 8.110.5 and up to 1.5cm thick in A. marginatum var. marginatum, Figure 2),wingless seeds (against winged seeds in A. marginatum

Grande do Sul, in areas occupied by restingas and dunes,A. marginatum var. marginatum is widely distributed,occurring in the north, northeast, west-central, south-east, and south o Brazil and in Argentina and Paraguay,in cerrado areas and predominantly in deciduousand semideciduous seasonal orests. Considering themorphological eatures mentioned above and thedifferences in geographical and ecological distributions,we propose a status change, elevating A. marginatumvar.apterospermumto the species level.
