General Description

Epiphytic herbs. Roots terete, sparsely branching, glabrous. Stem well developed, patent to erect, rooting. Leaves conduplicate, articulate, distichous, linear, thick-coriaceous, apex unequally bilobed. Inflorescence lateral, solitary, usually branching, manyflowered; peduncle elongate, pendent; rachis continuing the line of the peduncle, straight, finely pubescent; floral bracts conspicuous (unusual in this subtribe), covering the flowers, greenish yellow, often marked with maroon, finely pubescent. Flowers resupinate on a pendent inflorescence, about 0.5 cm wide, opening in succession, several at a time over a long period, quaquaversal, greenish yellow with maroon and purple markings. Sepals entire, free, obtuse, finely pubescent abaxially. Petals shorter than sepals, glabrous. Labellum rigidly attached, spurred, trilobed, with a single callus at the mouth of the spur just below the midlobe; spur saccate, parallel with ovary, without callosities inside. Column without column foot; pollinia four in two slightly unequal pairs, stipe longer than the pollinia, proximally forked, with one branch under each set of pollinia, longer than twice diameter of pollinia. Ovary densely and finely pubescent.
