Plant graceful, recalling 0. bracteatum Reichb. f. & 
Warsz. Pseudobulb pyriform, 2- to 3-leaved at the summit, 
5-8.9 cm. long, 2.5-3.8 cm. wide, somewhat compressed 
(1.3-1.9 cm. thick near the base), deeply sulcate, yellow, en¬ 
closed at base by a pair of leaf-bearing sheaths. Leaves 
lanceolate, 23-25 cm. long to the point of origin, 2.5-3.2 cm. 
■wide, obtuse and obliquely bilobed at the apex, gradually 
narrowed to a conduplicate petiole, subcoriaceous. In¬ 
florescence arcuate, paniculate, much surpassing the leaves, 
about 45 cm. long. Peduncle up to the lowest raceme about 
12.5 cm. long, entirely invested by distichous imbricating 
scarious sheaths. Racemes composing the panicle about 
3 cm. apart, 4-6 cm. long, arcuate-recurved, 5- to 9-flowered, 
subtended by a conspicuous bract which is lanceolate, sca¬ 
rious, concave and about 3 cm. long; rachis fractiflex, that of

bracts distichous, horizontally spreading, triangular-ovate, 
scarious, tubular-involute, up to 1.8 cm. long, carinate near

acute with a short dorsal apicule, margins slightly undulate 
and irregular. Petals oblong-ovate, 8.9-9 mm. long, 4.9-
