metric, about 8 cm. long and 9.5 mm. wide, acute, 4- 
nerved. Petals oblong-oval, about 2.4 em. long and 1.22 
em. wide, rounded above with a retuse tip, 7-nerved, 
adnate to the base of the col- 
umn. Lip broadly ovate in 
outline, deeply 8-lobed, very 
shortly and broadly clawed, a- 
bout 2.8 cm. long and 1.94 em. 
wide across the lateral lobes 
when expanded; lamina sub- 
cordate at base, provided with 
about thirteen approximate 
verrucose ridges of which the 
lateral ones on each side are 
sometimes broken into irregu- 
lar series of warts; lateral lobes 
semi-obecordate with rounded 
apex, about 1.15 cm. long; mid-lobe suborbicular-ovate, 
rounded at the apex, with undulate irregularly papillose 
margins, about 1.4 em. long and 1.8 em. wide. Column 
slender, about 1.9 em. long, abruptly dilated at the apex, 
narrowly winged on each side with the wing lightly di- 
lated below forming a concave base. 
This species appears to be distinct by reason of the 
sharply 8-lobed lip with the distinct verrucose lines on 
the disc. 
Lip, twice natural size.
