Scaphosepalum amethystinum Schitr.in Fedde 
Rep. Beih. 8: 119, 1921. 
This rare Ecuadorian species has been collected only 
twice since the original collection was made by Jameson 
in 1857. Porroglossum colombianum, as illustrated by 
Schlechter, is identical with P. amethystinum, of which | 
have studied the type. 
Porroglossum Xipheres (2?chb.f:) Garay comb. nov. 
Basionym: Masdevallia Xipheres Rchb.f. in Linnaea 41: 
12, 1876. 
Synonym: Scaphosepalum Xipheres Schltr. in Fedde 
Rep. Beih. 7: 220, 1920. 
When Reichenbach described Masdevallia Xipheres, 
he assigned it to the section ‘‘Kchidna’’. This section 
now comprises the genus Porroglossum. Porroglossum 
Xipheres is very similar to P. amethystinum in general 
appearance, but its hirsute peduncle and Restrepia-like 
petals easily differentiate the two species from one 
another.

Pleurothallis cuneifolia Cogn. in Mart. Fl. Bras. 3, pt. 
4: 441, 1906. 
An examination of the type of Pleurothallis hypnicola 
in the Lindley Herbarium indicates that P. cunezfolia is 
merely a form with luxuriant growth of that species.
