Synonym: Ornithidium compactum Schltr. in Fedde 
Rep. Beih. 7: 177, 1920. 
Pachyphyllum pamplonense Kral. in Pflan- 
zenr. IV. 50, Heft 83: 27, 19238. 
An examination of the type of Pachyphyllum pamplo- 
nense in the herbarium of the Natural History Museum, 
Vienna, shows clearly that Kraenzlin based his concept on 
a tracing of the type specimen of Ornithidiwm nubigenum. 
The record of the type of Camaridium compactum 
Schltr. in the Orchid Herbarium of Oakes Ames likewise 
has been found to be identical with Maailaria nubigena.

This rather common species is a close relative of Mail-

later homonym—hence the new name.
