is now moreover inappropriate, it may be changed to Dendrocya- 

 mus. 



To the same section belongs the following new species of Clitoria 

 from the Petersbnrgh herbarium. 



C. mucronulata, caule fruticoso glabro, ramis junioribus petiolis racemis* 

 que minute puberulis, foliolig oblongO'ellipticis vix acuminatis glabris vel 

 8ubtus margineque sparse puberulis, racemis paueiflovis folio brevioribus, 

 bracteolis ovali-oblongis calycem subsequantibus.— Ad Rio Madeira et Borba 

 in Brasilia. — Stipellae petiolulo breviores. Foliola omnia mucronulata- 

 Vexillum leviter adpresse pubescens. Legumen Junius villosum. 



114, Neuroc.arpum longifolium, Mart, in Bentb. Ann. Mus. Vind. ii. p, 

 116. var. longifolium. N. frigidulum, ejusd. 1, c.—British Guiana. Schom- 

 burgk. 



Since I described the above two plants I have seen intermediate 

 specimens which convince me that they are but varieties of each other. 

 The species has an extensive range from the Essequibo to the pro- 

 vince of Minas Geraes in Brazil. 



115, Neurocarpum cajanafolium, Presl. Symb. Bot. p. 17. t. 9.— =Savan- 

 nabs at Anna-y. Schomburgk, n. 58. It appears to be a common plant 

 from the Spanish Main to Rio Janeiro. It is Gardner's n, 960. from Per* 

 nambuco. 



The N.guianense, DC, or Crotalaria guianensis of Aublet, was by 

 mistake omitted in my memoir above-quoted. I have not seen it, 

 but from the figure and descriptions it appears to be near the two 

 preceding ones, but different from both. 



116. Centrosema vexillatum, caule herbaceo glabro, ramulis junioribus 

 pedunculisque puberulis, foliolis oblongo-ellipticis ovalibusve obtusis, pedun- 

 culis petiolo longioribus apice racemosis paucifloris, bracteolis ovalibus am- 

 plis calyce triplo longioribus extus puberulis, ealycis dentibus superioribus 

 brevissimis.— ^British Guiana. Schomburgk, n. 373. — Foliola 2 — 4-pollica- 

 ria. Stipellae setaceae. Bracteolas 10 lin. long®. Vexillum sesqui-pollicare, 

 latissimum. 



117. Centrosema brasittanum, Benth. in Ann. Mus. Vind. ii. p. 118. — 

 British Guiana. Schomburgk, n. 239. 



Allied to the above, but differing in inflorescence and form of 

 leaves, is the following from Sumadoris in Brazil, received from the 

 Academy of Petersburgh, 



C. brachypodnm, ramis petiolisque pubescentibus, foliolis ovatis acumi- 

 natis, basi subcordatis rotundatisve supra glabris subtus ad venas puberulis, 

 pedunculis brevissimis apice dense multifloris, bracteolis ovatis obliquis acu- 

 minatis calyce longioribus, dentibus calycinis superioribus brevissimis. 



The C. angustifolium was gathered by Salzmann at Bahia, and is 



in the Herbarium of the Academy of St. Petersburgh from Tejqco;
