Pleurothallis divaricans Schlechter in Fedde Re- 
pert. 10 (1912) 887; ex Mansfeld in Fedde Repert. Beth. 
58 (1980) t. 80, nr. 120. 
In several collections from Peru which are certainly 
referable to this species, some discrepancies trom the orig- 
inal description and floral analysis are noted. The stems 
(described as 4-7 cm. long) range from 8.5 to 10 em. 
long; the elliptic-lanceolate mature leaves (normally 
much longer) are occasionally only 8.5 cm. long; the 
inflorescences (described as little shorter than the leaves) 
often more or less surpass the leaves; the petals are ob- 
long-oblanceolate or oblong-spatulate and more or less 
acute (rather than oblong-ligulate and obtuse); and the 
lip when expanded is rhombic-obovate and abruptly nar- 
rowed above to an acute or apiculate apex (not subor- 
bicular). 
All of these collections came from near the type local- 
ity at altitudes ranging from 1200 to 1700 meters.

Judging by the description (without any actual rec- 
ord), it appears very probable that the concept described 
as Pleurothallis Millet by Schlechter in 1917 is referable 
to P. macrorhiza. It seems to differ, however, in having 
narrower leaves and somewhat smaller flowers.
