J.J.Smith (Blumea 1 (1984) 215) has called atten- 
tion to the fact that nota Schltr. is of dubious generic 
worth and has pointed out that nota violacea should be 
referred to the genus Rhynchostylis. With this interpre- 
tation [amin accord and should also place A nota densi- 
Hora in Rhynchostyls.

Stauropsis Imthurnii Rolte in Bot. Mag. (1917)

A study of this species indicates that it should be re- 
ferred to the genus Arachnis. The lateral lobes of the lip 
are entirely free from the column and the attachment at 
the base, in specimens which I have seen (probably from 
the type plant), is not so great as that shown in the above 
cited plate.
