ering time, represented by remnants of very narrowly 
elliptic blades whose long petioles are imbricating at 
base. Stem flexuous or erect, terete, entirely concealed 
by long tubular white-scarious imbricating sheaths which 
are 5-6 cm. long and are marked with brownish purple 
longitudinal nerves. Inflorescence a dense terminal ra- 
ceme, about 7-8.6 cm. long. Flowers small, spirally ar- 
ranged ,about thirteen to twenty, blossoming successively 
over a long period of time, much surpassed and mostly 
concealed by the scarious bracts which are ovate-lanceo- 
late, long-acuminate, concave at base and marked with 
about nine prominent longitudinal nerves. Dorsal sepal 
oblong-lanceolate, concave, about 9.5—-12 mm. long and 
3.2 mm. wide, acuminate, 3-nerved, recurved at apex. 
Lateral sepals linear-lanceolate, 9-11 mm. long, about 
1.8-2 mm. wide, acuminate, 8-nerved, recurving and 
“twisting to form loop which frequently holds bract of 
preceding flower tightly against stem.’’ Petals strongly 
adnate to the dorsal sepal forming a galea, distinctly 
shorter than the dorsal sepal, elliptic-linear, slightly sig- 
moid, 8-9 mm. long and 2.8 mm. wide in the middle, 
subacute to obtuse, 8-nerved. Lip recurved at the apex 
and upeurved at the base in natural position, pandurate 
with a distinct rounded constriction Just above the mid- 
dle, 9.5-12 mm. long when expanded, about 5-6 mm. 
wide just below the middle and slightly narrower above; 
the lower portion concave in natural position, flabellate- 
rhombie with rounded outer angles, cuneate toward the 
base with more or less thickened margins; anterior por- 
tion ovate, with inrolled crenulate margins, subacute to 
broadly rounded at apex when expanded; dise minutely 
papillose. Column small, oblique at base, 5.5 mm. or less 
long, dilated above, minutely papillose in front, with a 
triangular rostellum which is abruptly contracted to a 
linear-ligulate point. Anther cucullate-cordate.
