material, has been collected in three Peruvian localities. 
While the type collection consists of an incomplete 
secondary stem without any indication of a rhizome, all 
three of the Peruvian specimens show a creeping rhizome 
with more or less remote stems. 
Peru: Cuzco, summit of Ceochayoc, at 1000 meters altitude, Feb- 
ruary 21, 1931, C. Bues s.n.; Prov. of Convencién, Hda. Potrero, 
Sapan Sachayoce, at 2200 meters altitude, epiphyte in forest, flowers 
white, March 5, 1942, C. Vargas 2555; Machu Piechu, at about 
2100 meters altitude, May 22, 1915, O. F. Cook & G. B. Gilbert 866.

Whereas the type of this species came from Bolivia, 
a Peruvian collection referable to this concept has re- 
cently appeared. 
The plants forming this collection show some discrep- 
ancies from the description and from other examples of 
the type. One stem is 22 cm. long, in comparison with 
the cited length as about 15 cm. The lamina of one leaf 
is 16 cm. long, as contrasted with the attributed maxi- 
mum length of 14 cm. The inflorescences appear to be 
always solitary, not only in this Peruvian material, but 
also in all of the plants comprising the isotype Bolivian 
collection in the Ames Herbarium, despite the statement 
that the species always has two inflorescences. The flow- 
ers appear to be slightly larger than those of the type. 
Peru: Cuzco, Prov. of Quispicanchis, region of Murayaco and Mar- 
capata, at 1960 meters altitude, on rocks in sunny places, flowers 
yellowish green, January 28, 1943, C. Vargas 3134.

Although this concept has previously been noted only 
as a native of Bolivia, several Peruvian collections are 
now available. One of these collections shows a dorsal
