nearly 8 mm. long at the back, produced into a some- 
what longer narrow sulcate foot. 
This species seems to be nearly allied to the Colombian 
Mawillaria arachnites Reichb.f. which has differently 
colored flowers with a much shorter broader lip. The 
lobing and proportions of the lip distinguish this species 
from M. anatomorum Reichb.f. The Colombian M.ves- 
tita Schltr. appears to lack distinct elongate petioles and 
to have a smaller dissimilar lip.

Several authors, including Reichenbach filius and 
Cogniaux, have referred Scaphyglottis parviflora Poepp. 
& Endl. to the synonymy of Ornithidium vestitum or 
Mawxillaria purpurea as the latter concept becomes when 
treated as a Maxillaria (cf. Ames & Correll in Bot. Mus. 
Leafl. Harvard Univ. 11 (1948) 16). 
However, I feel reluctant to follow their example for
