 perennial herbs, occasionally annuals, but seldom trees.

These two species belong to a section of Crotalaria, which may 

 be called Anarthrophyllum and thus characterized : 



Folia simplicia, sessilia v. in petiolo brevi non articulata. Flores racemosi. 

 Calyces nunc profunde bilabiati bibracteolati, nunc subeequaliter 5-fidi 

 nudi v. minute bibracteolati. Legumen calyce longius v. rarissime 

 subbrevius. 



For the arrangement of the numerous species the section contains, 

 the groups proposed by Wight and Arnott (Prod. Fl. Penins. Inch 

 Or. p. 101 et seq.) appear to be natural, although they run much 

 into one another. Most of the species of their five first groups and 

 some of those of the sixth have a deeply bilabiate calyx, with the 

 lips sometimes scarcely divided, and bracteolae on each side often 

 nearly equal to the calyx itself; whilst those of the remaining groups, 

 with some species of the sixth, have a campanulate calyx, nearly 

 equally five-cleft, and the bracteolae very minute, often placed on the 

 peduncle below the calyx ; but the passage from the one to the other 

 is too gradual and too unconnected with habit to be made use of in 

 characterizing the groups. 



To the Alatce, to which both the above species belong, I should 

 also refer several new Brazilian species, of which I subjoin the spe- 

 cific characters, reserving fuller descriptions for the ' Legumino- 

 sarum Genera et Species' which I am preparing.

 rioribus decurrentibus, apice oblique truncatis, racemis terminalibus multi- 

 floris. — Rio Uruhu and Villa Boa. Pohl. 



C. bracteosa, fruticosa elata, ramis glabris, stipulis superioribus latis
