This variety differs from the type chiefly in the tomentose branch- 

 lets and leaves; it shows considerable variation in size and shape of 

 its leaflets and fruits. Thornber's No. 299 differs in its oblong- 

 elliptic, nearly sessile leaflets. Greene's No. 37 has broader, elliptic 

 to ovate-oblong leaflets. Palmer's No. 592 has similar leaflets, but 

 narrower fruits from 1.5-3 cm. long. Blumer's No. 1302 has 5-7, 

 rather broad, ovate to elliptic leaflets and is much less densely pubes- 

 cent than the type. Also Griffith's No. 5390 is less pubescent and 

 has 5-7 narrower, rather sharply serrate leaves.
