I have studied the type of Pleurothallis parva in the 
Kew Herbarium and have found it to represent the well- 
known P. sonderanoides. 
Restrepia nittiorhyncha ( Lindl.) Garay comb.nov. 
Basionym: Pleurothallis nittiorhyncha Lind]. Folia. Orch. 
Pleuroth. 20, 1859. 
Synonym: Restrepia Schlimu Rehb.f. in Linnaea 41: 45, 
1876. 
Examination of the type specimens of both Pleuro- 
thallis nittiorhyncha and Restrepia Schlimi fail to reveal 
any differences between them either in vegetative ap-

Gart. Berlin 7: 324, 1919. 
An examination of the type of Pleurothallis chloido- 
phylla revealed eight pollinia in the anther. Octomeria 
Dusenit, of which I have seen ample material, is con- 
specific with O. chloidophylla. 
Octomeria sagittata (Ichb.f.) Garay comb. nov.

It is unfortunate that Reichenbach chose a rather 
badly shrivelled flower upon which to describe and illus-
