1.5 mm. long, about 0.7 mm. wide at the base. Lip 
arcuate-decurved in natural position, linear-oblong when 
spread out, obtuse, slightly dilated below the middle with 
the margins somewhat upturned, apical margins deflexed, 
silky-pubescent along the margins, with asmall incurved 
auricle on each side at the base, 2.5 mm. long, about 1 
mm. wide; disc obscurely 3-nerved, provided in the mid- 
dle of the lower third with a linear callus which divides 
and extends above the middle of the lip as two slightly 
thickened ridges. Column short, stout, fleshy, irregularly 
serrate at the apex, 1.5 mm. long, with a broad foot about 
1 mm. long. Capsule subglobose, about 5 mm. long. 
This species is closely allied to P. Blaisdellii S. Wats. 
and P. gnomonifera Ames, but differs mainly in its entire 
triangular petals and essentially glabrous sepals.

Variety Ga/eottiana is distinguished from the typical 
form of the species mainly in the size of the flowers, in the 
shape and coloration of the lip and in the size of the leaf. 
The lip of var. Galeottiana is brownish purple to almost 
maroon, not constricted above the middle, broadly ovate- 
oval to oval-subquadrate, subtruncate to obtuse at the 
apex, often with conspicuous auricles at the base and is 
usually about 10 mm. long and 8 mm. wide. The lip of 
L.vewillifera is greenish marked with purple, with a defi- 
nite constriction above the middle, erbicular-ovate to
