The writer has followed Miqnel and Baker in uniting these two plants which 

 Linnaeus, De Candolle, Wallich and Wight have endeavoured to keep distinct. The 

 difficulty that has arisen in distinguishing them, has been due to the fact that 

 A. vaginalis, though always diagnosed as having lower leaves lanceolate and upper 

 leaves oblong, in reality very often has the lower oblong and the upper ovate as in 

 A. nummular if olius. The true distinguishing characters are the spreading habit and 

 condensed racemes of the variety, the ascending stems and lax racemes of the 

 typical plant. The description and the varietal diagnoses now given may, it is 

 hoped, prevent a recurrence of the difficulty that has hitherto been experienced in 

 differentiating the two. 



41. Desmodium Desv. 



Herbs or shrubs. Leaves 1- or 3-foliolate, stipellate. Flowers small 

 usually in copious often dense racemes. Calyx campanulate ; teeth 

 longer or shorter than the tube the two upper often subconnate. Corolla 

 exserted ; standard broad ; wings more or less adherent to the usually 

 obtuse keel. Upper stamen entirely or partially free from the other 

 united 9. Ovary sessile or stipitate, few- or many-ovuled ; style in- 

 curved, stigma minute capitate. Pod usually composed of several 

 1-seeded indehiscent joints, the faces compressed, the upper suture 

 rarely finally splitting open, the joints usually separating. Species 

 about 150 ; cosmopolitan in tropical and subtropical countries, a few 

 in temperate N. America and temperate S. Africa.
