transversely bilobed with the lobules set at an obtuse 
angle; posterior lobule obliquely oblong-ovate, obtuse, 
about 2 mm. long; anterior lobule oblong-lanceolate, 
obtuse, little shorter but much narrower than the poste- 
rior lobule. Lip adnate to the column in front, 3-lobed; 
lateral lobes prominent, obliquely triangular, about 2 
mm. long, with a peltate lanceolate apex which is about 
2mm. wide; mid-lobe minute, triangular-linear. Column 
stout, arcuate, dilated above, about 2 mm. long. 
Lepanthes alticola is apparently related to the Colom- 
bian ZL. costata Reichb.f., but differs in having dissimilar 
petals and lip. It varies from the Bolivian L. rupicola 
Schltr. in its longer stems, larger leaves and dissimilar 
petals.
