BKNTIIAM ON JIIMOSEiE. 375 



with both descriptions of pod: in the third and fourth it is 

 articulate wherever I have seen it, and in the fifth inarticu- 

 late. Yet it is unknown in so many, that I can place no reli- 

 ance on this character.

56? M. calocephala (Mart. Herb. Fl. Bras. 133.), and 

 57? M. hypoglauca (Mart. I. c), Prov. Minas Geraes and 

 Bahia, Martins. 



I cannot recognise either of these species in any of the 

 specimens before me. They are fousid together and are said 

 to be nearly allied to each otlier. Independently of the 

 characters derived from the foliage and hairiness, all the fol- 

 lowing species are racemose, not corymbose. The only 

 specimens where I have observed any approach to the corym- 

 bose inflorescence (the racemose being much shorter,) are 

 among the £! rioc aides ; but in those the leaflets are scarcely 

 glabrous, and not near so glaucous, besides that tliere is no 

 species among them at all resembling my J/l rigida.
