about 5.5 mm. long and 8.8 mm. or less wide. Petals 
cuneate-flabellate with recurved sides in natural position, 
oblong-obovate when expanded, broadly rounded at the 
apex, l-nerved, about 5 mm. long, 8.5—-4.2 mm. wide, 
2- to 8-nerved. Lip deeply 8-lobed, shorter than the other 
segments in natural position, with saccate base, erect lat- 
eral lobes and recurved mid-lobe, when expanded about 
6.5 mm. long and slightly wider across the base; lateral 
lobes small, divaricate, triangular-oblong, with a recurved 
convex apex; mid-lobe much larger, subquadrate-ovate 
when expanded, slightly dilated above and below, rather 
abruptly narrowed above to an acute tip, 7-nerved; disc 
with a transverse subelliptical pluridentate callus which 
extends as a toothed ridge from the base of the lateral 
lobes, continues in a curved line in front of the lateral 
lobes and is extended across the base of the mid-lobe. 
Column very small, clavate, with a reflexed linear ros- 
tellum. 
In the Ames Herbarium there is a drawing of Ornitho- 
cephalus polyodon from the Reichenbach Herbarium con- 
sisting of two flowering racemes and a rather detailed 
floral analysis. The latter shows a close agreement with 
the flowers of the Peruvian collection, having similar 
oblong-obovate sepals with a broadly rounded apex. The 
petals are shown as sometimes broadly rounded and 
sometimes (as described) retuse at the apex. The lateral 
lobes of the lip (as drawn) appear to be subequal in size 
to the mid-lobe. The type description, as well as the 
Reichenbach drawing, shows that there is a toothed up- 
per margin of the petals, a character which does not ap- 
pear in our specimen.
