NOMENCLATORIAL NOTES XII 
BY 
CHARLES SCHWEINFURTH 
Pleurothallis setosa C. Schweinfurth nom. nov. 
Masdevallia fimbriata A. & S. in Sched. Orch. 10 
(1980) 18. 
A careful examination of the floral parts of this species 
convinces me that it should be referred to the genus 
Pleurothallis; but the combination P. fimbriata has pre- 
viously been used by Lindley fora Brazilian species, thus 
necessitating a new specific epithet. 
This species appears to be allied to Plewrothalls sam- 
acensis Ames, but has much narrower leaves, setose pe- 
duncles and larger flowers with dissimilar lateral sepals 
and lip. It was described from Costa Rica. 
Recently this concept has been recorded from British 
Honduras. In this collection the peduncle appears to be 
even more conspicuously setose-pubescent than in the 
type.
