Description
|
Epiphytic herbs, with fleshy cylindric, fusiform or clavate, pendent pseudobulbs 15-20 cm. long and 1-2 cm. wide. Leaves plicate, lanceolate, acute or acuminate, 6-40 cm. long and 1.2-3.5 cm. wide, the imbricating bases persistent, enclosing the pseudobulbs, the blades ultimately deciduous. Inflorescences usually solitary, short racemes produced from the axils of one of the bracts of the leafy new growth. Flowers 3-7, 2.5-3 cm. long in dried specimens but probably somewhat larger when fresh. Dorsal sepal free, erect, elliptic-oblong, obtuse, 2-2.2 cm. long and 1.2-1.5 cm. wide, lateral sepals obliquely cuneate, 2.2-2.5 cm. long and 1.6-1.8 cm. broad, connate at the base and adnate to the column foot, forming a rounded mentum. Petals obovate-lanceolate, acute, 2-2.2 cm. long and 0.9-1.1 cm. broad. Lip 3-lobed, the lateral lobes subfalcate, obtuse, erect, the apices somewhat convergent, the mid-lobe rounded in general outline, more or less cymbiform, the apex 2-lobed or emarginate; disk with 5 fleshy, longitudinal crests. Column short, stout, broadly winged, 0.9-1.0 cm. long and 0.9-1.0 cm. broad at the base, which is produced into a foot.
