Description
|
Erect, caespitose, epiphytic herbs averaging about 30 cm. tall. Leaves fleshy, linear-lanceolate, obtuse to acute, 6-3 5 cm. long and 1-3.8 cm. wide, the conduplicate bases imbricating and forming a short, more or less complanate petiole, sometimes enveloping an inconspicuous, poorly developed, oblong, monophyllous pseudobulb, all but the leaf of the pseudobulb actually being foliaceous bracts. Inflorescences usually short, solitary, 1-flowered scapes, nearly sessile in the upper bract axils. Flowers of moderate size. Sepals subequal, free, spreading, usually yellow or pale yellow, lanceolate, acute, 16-20 mm. long and 5-6 mm. wide, the dorsal sepal somewhat concave, the laterals adnate to the column foot, forming a short, rounded mentum. Petals usually yellow, subequal to the dorsal sepal, linear- lanceolate to oblanceolate, acute, 14-17 mm. long and 3-4 mm. wide. Lip nearly entire or obscurely 3-lobed, yellow with red spots to dark red, concave, 12-14 mm. long and 5-7 mm. wide when spread out, contracted at the base and articulated with the column foot, lateral margins erect, the mid-lobe about 1/3 to 1/2 the total length of the lip, somewhat thickened and minutely papillose; the disk with a fleshy, thickened keel. Column elongate, semi-terete, somewhat arcuate, 7-9 mm. long, produced at the base into a short foot.
