elongate branch above, leafy above, entirely or mostly 
concealed by tubular sheaths which are close scarious and 
evanescent below and leaf-bearing through the upper 
portion of the stem. Leaves distichous, lanceolate or 
elliptic-lanceolate (rarely oblong-lanceolate), up to 12.5 
em. long and 2 cm. wide (the lower blades much small- 
er), minutely erose at the acute or more often acuminate 
apex, sessile, amplexicaul, spreading, subcoriaceous. Ra- 
ceme terminal, arcuate, loosely several-flowered (appar- 
ently incomplete in my specimen). Peduncle about 4.2 
cm. long, mostly concealed by a slender tubular spathe 
with an oblong-lanceolate acute free portion. Floral 
bracts conspicuous, narrowly — triangular-lanceolate, 
spreading. Flowers medium-sized, greenish white, with 
spreading or reflexed segments. Dorsal sepal obovate- 
oblong, acute, about 16.7 mm. long and 6 mm. wide, 
5-nerved. Lateral sepals obliquely oblong-obovate, sharp- 
ly acute, lightly carinate especially above, about 15 mm. 
long and 6 mm. wide. Petals spatulate-linear, obtuse, 
about 16 mm. long and 38 mm. wide, 8-nerved, with the 
upper margins minutely erose. Lip adnate to the column 
nearly to its apex: lamina convex in natural position, 
subquadrate-reniform when expanded, lightly cordate at 
base, shallowly but distinctly 3-lobed at the truncate 
apex, about 8.9 mm. long from the base to the tip of a 
protuberant side of the mid-lobe and 17.9 mm. wide; lat- 
eral lobes semiorbicular or rounded-dolabriform, with the 
outer margins irregular; mid-lobe transversely oblong or 
renitorm, shallowly retuse, 1.2-2 mm. long and 6.4-8.2 
mm. wide; disc at base with a pair of prominent spread- 
ing free hgulate calli which are about 4 mm. long and 
with a fleshy-thickened median line. Column conspicu- 
ous, abruptly dilated above in front, produced on each 
side into an obliquely subquadrate auricle, about 12 mm. 
in greatest length.
