General Description

Epiphytic, lithophytic, or terrestrial, caespitose herbs. Roots often rugose, broad and flat in epiphytic species, terete in terrestrial species. Rhizomes erect or ascending. Stems swollen at base, slender above, erect to nodding, composed of 2–4 internodes, bracts scarious, imbricated, sheathing. Leaves articulate, 1–4, conduplicate, coriaceous to rigid, serrulate-crenulate, blades inrolled, ligulate to narrowly lanceolate. Inflorescence racemose, 1–8-flowered, bracts few, distant, sheathing to erect-spreading. Flowers produced in succession, resupinate. Sepals spreading, glabrous, concave, the lateral sepals sometimes adnate to the base of the column. Petals free, spreading, glabrous, of thinner texture and narrower than the sepals. Labellum clawed, basally adnate to column, deeply trilobed, flat, lateral lobes free from column, midlobe emarginate to short-apiculate, disc with a basal callus, merging into a few low keels, puberulent to short-echinate. Column semiterete to flattened, clinandrium with a variable tooth on each side; anther terminal, operculate, incumbent, two-chambered with each divided into four cells, pollinia eight in four unequal pairs, rarely with an additional four rudimentary pollinia, laterally compressed, hard, waxy, connected by caudicles; stigmas confluent, entire, rostellum transverse. Ovary glabrous with an enclosed nectary forming an extension of the throat of the labellum. Capsule ovoid to ellipsoidal, ribbed. (JA).

Ecology

Only one species, Q. ekmanii Dod, is terrestrial in leaf litter pockets and limestone rocks on steep slopes and cliffs. All others are epiphytic. A few species are locally common, whereas others are known only in low-density, scattered populations. (JA).

Distribution
