perfectly glabrous, except for the more or less black-strigose 

 calyx, but sometimes the upper part of the stem and the lower 

 surface of the leaflets are slightly strigose. This is the case with 

 6 1 . Watson 283, which was mistaken for S. filipes. Watson's 

 description of that species also applies to H. stenophyllus.

 leaves are strigose-canescent. It has been mistaken for H. An-
