Caules aggregati, elongati, basi attenuati, folia lanceolata, 
acuta, 13 ad 17 cm longa, 1.5 ad 2.6 cm lata, gerentes. Racemi 
brevissimi, 7-vel 8-flori, e caulibus defoliatis orientes. Flores 
circiter 5 cm longi, 4 cm lati. Sepala lateralia obliquissime 
triangulari-ovata, in apice cucullata, 1.8 ad 2.4 cm longa, se¬ 
cundum columnae pedem 2.5 ad 3 cm lata; mentum valde elon- 
gatum, superne abrupte reflexum. Sepalum dorsale ovato-lan- 
ceolatum, obtusum vel subacutum, 1.8 ad 2.6 cm longum, 9 ad 
12.5 mm latum. Petala oblongo-elliptica, obliqua, in apice ro- 
tundata, 1.8 ad 2.4 cm longa. Labellum perbreviter, 3.3 ad 4 
cm longum, obscurissime trilobum; lobi laterales breves, erecti, 
late rotundati; lobus intermedius productus late ovatus, abrupte 
acutus, reflexus, discus glaber. 
Stems terete, aggregated, elongate, 66 to 95 cm tall, leafy, 7 
to 10 mm in diameter at the middle, 3 to 5 mm across at the 
base; the nodes 1.5 to 4.5 cm distant. Leaves distichous, deci¬ 
duous, lanceolate, acute, 13 to 17 cm long, 1.5 to 2.6 cm wide, 
9-nerved, membranaceous, greenish, articulated to tubular 
sheaths. Leaf sheaths up to 4.5 cm long, membranaceous, decid¬ 
uous on the lower part of the plant. Flowers 7 or 8, in very 
short lateral racemes, about 5 cm long, 4 cm across, with a 
strongly curved spur. Peduncles sheathed, about 5 mm long 
below the flowers, the rachis about 1.5 cm long, glabrous. Bracts 
lanceolate, purplish, up to 5 mm long. Pedicellate ovary 3.5 
to 4 cm long, pale flesh color, pedicel slender. Lateral sepals 
very obliquely triangular-ovate, obtuse or subacute, somewhat 
cucullate at the tip, 1.8 to 2.4 cm long, about 2.5 to 3 cm wide 
along the column-foot. Dorsal sepal cucullate, reflexed, ovate- 
lanceolate, obtuse or subacute, 1.8 to 2.6 cm long, 9 to 12.5 mm 
wide, 7-nerved. Petals oblong-elliptic, oblique, rounded at the 
tip, 1.8 to 2.4 cm long, 1 to 1.2 cm wide, 7-nerved, margin entire. 
Labellum very shortly unguiculate, 3.3 to 4 cm long, cuneate- 
obovate, narrowed to the base, sharply bent at the base to con¬ 
form to the curved spur formed by the mentum of the lateral 
sepals, very obscurely 3-lobed; the lateral lobes erect, broadly 
rounded; the front lobe produced, broadly ovate, abruptly acute, 
about 1.8 cm wide at the broadest portion, reflexed; the disc 
glabrous with a small hippocrepiform callus at the base. Column 
white, very short and stout, about 5 mm long, extended in an 
elongate foot. 
The flowers are odorless, white with the apices of the petals 
and the labellum flushed with mallow pink or phlox purple; the
