Beihefte 19 (1928) 289. 
A record of the type of Pleurothallis pilosissima in- 
cluding floral analysis has recently been supplemented by 
a collection of this remarkable species from Costa Rica 
(4. M. Brenes (116) 1320). 
Evidently this species does not belong to the genus 
Pleurothallis, for its flowers show the clavate termination 
of the dorsal sepal and of the petals which is a character- 
istic feature of the genus Restrepia. Moreover, the lip, 
while somewhat more complicated than in the recorded 
members of Restrepia, still has the general aspect which 
obtains in the genus. 
To be sure, the analysis of the species by Dr. Schlech- 
ter shows but two pollinia, whereas Restrepia has four 
pollinia. Also the Brenes collection cited above shows 
but two pollinia in its single available flower. However, 
the relatively broad, 2-chambered anther indicates that 
two additional pollinia were originally present. 
This species is most unusual for Restrepia because of 
its excessively villous character throughout.
