acute tip, 3-nerved, with the lateral nerves hardly reaching

A _^close ally of Pleurothallis Schulzeana Schltr., from 
which it differs in the larger flowers with broader floral 
segments. In P. Schulzeana the petals are linear rather than 
lanceolate, and only 2.75 mm. long. P. lancilabris (Reichb. 
f.) Schltr. is another close ally of P. propinqua, but differs 
from it in having much smaller flowers.
