CLEISTOGAMY IN CUBELIUM -5or 
VOLUTELLA 
The name Volutella Tode seems inapplicable because of an 
older Volutella Forsk* (1775). ‘The alternative Thysanopyxis Ces. 
would appear to deserve to replace the other name. 
STEINERA 
The Sternera Zahlbruckner is a homonym to Steineria Klotsch? 
and may be changed to Molybdoplaca the specific name of one of 
the species. 
Molybdoplaca Nom. Nov. 
Stetnera Zahlb. not Klotsch 1. ec.

Steinera molybdoplaca (Nyl.) A. Zahlb.

by mycologists, seems a homonym to the earlier 7Tvtania Endl 
(1833). Fremineavia is suggested as a substitute. Henri Fremineau4 
was a physician and author of a system of cryptogamic plants.

appear as abundantly or readily as in the violets proper. Should
