somewhat suleate above and carinate beneath; petiole 
distinct, conduplicate, long or very short, up to 4 cm. 
in length. Inflorescences short, 1-flowered, solitary, in 
the axils of the imbricated sheaths of the stem. Peduncles 
concealed by several conduplicate lanceolate or ovate-lan- 
ceolate imbricated acuminate bracts. Flowers medium- 
sized. Dorsal sepal elliptic-lanceolate or oblong-lanceo- 
late, strongly coneave, about 14.9-16 mm. long and 
5-6 mm. wide, complicate-acute, 7- to 9-nerved, dor- 
sally carinate toward the apex. Lateral sepals oblong- 
lanceolate, acute or subacute, somewhat asymmetric, 
about 13.5-15 mm. long, 4.5—5 mm. wide near the base, 
6- to 7-nerved. Petals oblong, acute, about 12-14 mm. 
long, 8 mm. wide, acute, 5-nerved, with a slight concavity 
near the apex on the posterior margin. Lip rigidly at- 
tached to the column-foot, sigmoid-curved below, about 
11.5-12.8 mm. long in natural position, deeply 3-lobed 
about one third the length from the apex, with the basal 
portion (about 5 mm, long) deeply saccate, the sac por- 
rect and almost contiguous to the abruptly reflexed cen- 
tral portion; lateral lobes erect, spreading, semicuneate, 
with a straight anterior margin, free portion about 2.5 
mm. wide; mid-lobe small, strongly conduplicate, con- 
cave at the base, broadly ovate when expanded, compli- 
‘ate-acute, about 4-5 mm. long; dise with a small fleshy 
oblong-ovate suleate callus which extends from the sinus 
of the lateral lobes as a free projection above the lower 
portion of the mid-lobe. Column slender, about 8-8.9 
mm. long, slightly arcuate, extended into a short foot 
forming a mentum with the lateral sepals. 
Two additional collections bearing the imperfect re- 
mains of the perianth at the summit of enlarged ovaries 
show larger leaves than the type. In Standley 33065 the 
longest leaf is 18 cm. in length, while in Standley 33058 
the broadest leaf is about 4.9 em. in width.
