with cross-veins above the middle, about 7.5 mm. long 
and 1.5 mm. wide. Lateral sepals narrowly and obliquely 
oblanceolate-oblong, subobtuse, strongly navicular espe- 
cially above, dorsally carinate with the sparingly ciliate 
keel broadened near the apex and extending as an apicule, 
5-nerved, with cross-veins above the middle, 6.6—7 mm. 
long, about 1.5 mm. wide near the apex. Petals linear- 
faleate, subacute to shortly acute, 3-nerved, with a few 
cross-veins near the apex, about 6.5 mm. long. Lip ad- 
nate to the column by a thickened mid-nerve for almost 
one third the length of the lamina, obovate-pandurate in 
outline from a narrowly cuneate pubescent base, 6.6 mm. 
long; lateral lobes shallowly semiobovate, subacute in 
front with the anterior margins fleshy-thickened, the 
lower margins ciliate, upturned and clasping the column 
in natural position, about 8 mm. wide across the lobes 
when spread out; mid-lobe obovate-reniform, retuse or 
bilobed and apiculate with the lobes spreading and irreg- 
ularly erose-ciliate, about 8 mm. wide; disc pubescent at 
the base, with conspicuously branching veins above, pro- 
vided in the constricted portion with a U-shaped fleshy 
callus and a more or less distinct fleshy thickening be- 
tween the lateral arms of the callus. Column slender, 
glabrous, with two narrow lateral wings on the anterior 
surface, somewhat arcuate above, about 6 mm. long; 
anther terminal, semiorbicular-conic, incumbent, oper- 
culate with a slender hinge, 2-celled. 
In regard to the flowers, Palmorchis pandurata has 
a lip resembling in size that of P. guianensis but in out- 
line the lip suggests that of P. pubescens.

ever, we did learn from authorities in Colombia that the place is not 
in that country.
