form of the. same species as is also D. asperella. The assumption of 



Greene that p. Helleriana is a subalpine species because of the locality 



in , which it was got, which he assumed was in the high mountains vr^s 



completely disproved by Heller. But it is a fact that formi= oT. aurea 



with long styles are subalpine, and it i"5 not possible to dmw ?ny line 



between aurea, streptocarpa and Mpgollonica that will 'hold water. 



Greene's assumption that no forms of real aurea exi^^t In .Gii? -cotintrr 



still nc^s confirmation. Other' sjnonj^ns are D, jiinetonim, ?EnH gjcc-
