Microstylis brachyrrhynchos Reichenbach filius in 
Flora 71 (1888) 152. 
Malaaxis Lankestert Ames in Sched. Orch. 4 (1928) 7. 
A rigid comparison of the type specimen of the 
Costa Rican Malaais Lankestert shows that it cannot 
well be segregated from the Mexican Microstylis brachyr- 
rhynchos which is represented in our herbarium by photo- 
graphs of the type and cotype and floral analyses. 
Judging from the floral analyses of the type and co- 
type and from the numerous examples of this species in 
our collection, the distinctness of the apical lobing of the 
lip and presence of basal auricles is a variable character. 
The lip appears to vary from simple to obscurely trilo- 
bulate or more rarely distinctly trilobulate at the apex. 
This species occurs in our herbarium from Mexico, 
(juatemala, Honduras and Costa Rica.
