cent's and in Central America. It is Cuming's n. 1097. from Pa- 

 nama. 



The name of Stenolobium had been given by Don to a genus of 

 Bignoniacea;, and I have therefore in some herbaria given the name 

 of Cyanostremma to my genus ; but as it now appears that Don's 8te- 

 nolobium is not adopted, mine may retain that name. The following 

 gathered by Salzmann at Bahia is a fourth species : — 



S. velutinum, foliolis concoloribus, calycibiis querufo-velutinis, legumini- 

 bus piloso-hispidis. — Calyces 4 lin. longi, tubuloso-campanulati. Corolla 

 intense colorata, 8 lin. longa. 



120. Galactia velutina, volubilis, mollissime villosa, foliolis 3 ovalibus 

 obtusis basi subcordatis supra velutino subtus subsericeo-villosis, pedunculis 

 brevissimis paucifloris, laciniis calycinis tubo subtriplo longioribus corolla 

 parum brevioribus. — British Guiana. Schomburgk, n. 649. 



A somewhat coarse species with larger leaves than most of the 

 American species. They somewhat resemble in form those of G. ca- 

 nescens (Texas, Drummond, 2nd Coll. n. 81. 3rd Coll. n. 146.), but 

 the species is readily known by the soft down of the whole plant. 



Cologania heterophylla of Gillies, judging from Tweedie's speci- 

 mens, is a Galactia very near to, if not identical with, G, marginalis, 

 which is Drummond's n. 145 of his third Texas collection. 



121. Collaa rosea, caule sufTruticoso erecto? tomentoso-yilloso, foliolis 

 3 ovali-ellipticis utrinque obtusis submucronatis coriaceis supra pubescen- 

 tibus subtus molliter villosis, pedunculis folio subbrevioribus interrupte ra- 

 cemosis, calycis villosi laciniis lanceolatis tubo parum longioribus, vexillo 

 glabro, leguminibus cano-velutinis. — British Guiana. Schomburgk, n. 261. 



Near C. Neesii and C. Martii. Flowers much smaller than in the 

 former and racemes much shorter. I do not possess specimens of 

 C. Martii, but the present plant does not agree with the descriptions 

 of it. 



122. Dioclea lasiocarpa, Mart. Benth. in Ann. Mus. Vind. ii. p. 133.. 

 —French Guiana. Herb. Par. n. 39 and 48. It is also Gardner's n. 970 

 from Pernambuco, and perhaps DoUchos comosus of Meyen's Esseqiiibo 

 Flora. 



123. Dioclea guianensis, Benth. 1. c. p. 134. — British Guiana. Schom- 

 burgk, n. 83. — 5. villosior, foliolis supra pubescentibus, subtus dense seri- 

 ceis, venis petiolisque rufescentibus. — British Guiana. Schomburgk, n. 629. 



Gardner's n. 353 from the Organ Mountains is Cleobulia multi- 

 flora. Mart., his n. 355 from the same chain is Canavalia picta, Mart., 

 var. longiracemosa. Cuming's n. 1204 from Panama is a slight va- 

 riety of Canavalia ohtusifolia, DC. Blanchet's n. 2748 from Utinga 

 in the province of Bahia is Canavalia hrasiliensis , Mart., which spe- 

 cies is also in Salzmann's Bahia collection.
