cordate at the base, about 2.2 mm. long from the center 
of the base to the apex of a lateral lobe and 2.6 mm. 
wide at the base; lateral lobes relatively large, obliquely 
semiovate, incurved above, obtuse; mid-lobe minute, 
triangular-ovate. Column slender, shorter than the lip, 
more or less dilated above. 
This little plant resembles Lepanthes pumila C. 
Schweinf. in habit, but not in floral structure. It differs 
from L. cassidea Reichb.f. in its oval leaves and lack of 
cilia on the petals and lip. It varies from L. Millei 
Schltr. in having densely flowered racemes and dissimi- 
lar petals which Jack a median lobule.

Pleurothallis bicornis Lindley Fol. Orch. Pleuro- 
thallis (1859) 7, no. 29. 
A critical examination of a photograph of the type of 
this species in the Lindley Herbarium suggests several 
corrections in the original description. 
The leaf appears to be ovate-oblong, rather than ‘‘ob- 
long.’” While this organ is described and shown as ‘“‘de- 
flexed,’ that condition seems to be due to the fact that 
the base of the lamina has evidently been broken and 
torn from its natural junction with the stem and bent 
down in the dried specimen. It seems quite evident, 
also, that the cauline sheath was detached from the stem 
in the type specimen and that it was pushed up the stem 
to the origin of the leaf, a condition which is rarely seen 
in natural specimens. 
Several recent Peruvian collections referable to Pleuro- 
thallis bicornis show the need for a few additional correc- 
tions. The leaf, which varies from ovate-oblong to 
oblong-elliptic, is 9.2-14.7 cm. long (not 17.5 cm. as 
shown). It is always acute at the apex (not acuminate)
