Characteristics

Herbs, epiphytic or lithophytic, monopodial, small. Roots radiate, appressed to tree trunk or branch, green and photosynthetic in rainy season, whitish or grayish in dry season, flattened or terete, rather long and stout. Stems short, nearly invisible. Leaves absent or reduced to tiny brown scales. Inflorescences lateral, short; rachis slowly elongating, with flowers opening in succession 1 or 2 at a time; floral bracts persistent, alternate. Flowers usually lasting only a day, small. Sepals and petals free and widely spreading or connate at base or below middle into a tube. Lip entire or 3-lobed, attached to base of column, spurred or saccate, often with an apical reflexed tooth or bristle; spur globose to cylindric. Column short, stout, footless; rostellar projection variable; anther cap terminal, often beaked; pollinia 4, waxy, subglobose, equal, separate from each other, with a common stipe and an oblong or elliptic viscidium.

Small, leafless, epiphytic orchids with flat, round or triangular (in cross-section) green (photosynthetic) roots. Stems almost vestigial. Racemes thin, glabrous or hairy; rachis with prominent bracts, continuing growth and flowering intermittently. Flowers resupinate, small, 1–3 open at once, often tubular with spreading tips, sometimes opening widely, lasting 1–3 days. Sepals and petals either fused at base or free and spreading widely. Labellum fixed to base of very short column by top of spur. Labellum lamina unlobed or 3-lobed; midlobe often with short, apical, tooth-like appendage. Column short without basal foot. Pollinia 4, orange, hard, waxy, sessile, attached via stipe to viscidium.

Column very short; anther erect with 4 pollinia in 2 unequal pairs; stipes and viscidium 1; rostellum, minutely 3-lobed.

Flowers resupinate; sepals and petals similar, united for part of their length; lip free, spurred.

Leafless epiphytic herbs with short, simple stems; roots abundant, photosynthetic.

Inflorescence axillary, racemose.
