This being a second species of a genus founded several years 

 ago by myself, the examination of the specimens and comparison

 lata) has been a matter of much interest to me. I hud all the 

 generic characters peculiar to the latter, with one small exception, 

 shared by the plant here described; these are, tha contorted 

 aestivation — the corolla lobes opening very early, so that small buds 

 must be selected if one wishes to make out the aestivation satis-
