Pleurothallis Urbaniana Reichenbach filius in 
Ber. Deutsch. Bot. Gesell. 8 (1885) 279—Cogniaux in 
Urban Symb. Antill. 6 (1909) 411. 
Pleurothallis dichotoma Ames in Sched. Orch. 6 (1928) 
58, non Seblitr. 
Pleurothalhs divewa Ames in Sched. Orch. 7 (1924) 
20. 
It appears certain that the Central American Pleu- 
rothallis divexa is referable to the West Indian P. Ur- 
baniana. The range of the species, as at present known, 
extends from Costa Rica and probably Panama to Gua- 
deloupe and Porto Rico. 
As to the color of the flowers, Cogniaux (l.c.) says 
of the Porto Rican plant: ‘‘F lores albidi, intense rubro- 
striati.’”> One specimen of P. Urbaniana from Guade- 
loupe (H.Stehlé 1295) shows the flowers yellow. How- 
ever, the Costa Rican P.divewa has the flowers maroon- 
purple, purple-red, or “‘hyaline, purple marked. ’’
