Distribution

Micropera comprises about 20 species collectively distributed from India (Sikkim), Bhutan, China (Hainan), and Indochina, south to Malaysia and Indonesia, east to the Philippines, New Guinea, Australia, and the Solomon Islands.

Ecology

Species are epiphytes in swamp and broad-leaved forests from 0 to 1200 m. Micropera pallida climbs up tree trunks where light levels are high along roadsides, on isolated trees in scrub, and on cultivated village trees in Sumatra and Java. Micropera sterrophylla (Schltr.) Garay is epiphytic on the branches of large roadside trees at 600–1200 m in Sulawesi.

General Description

Climbing, epiphytic herbs. Stem simple or branching, up to 1 m long, internodes to about 2 cm long, bearing many support roots at intervals. Leaves linear, to 17 × 2 cm, usually much less. Inflorescence lateral, leaf-opposed, bending through a right angle so the rachis points either straight up or straight down, racemose, to c. 15 cm long, few- to many-flowered. Flowers usually non-resupinate, fleshy, usually yellow with purple markings, or pink. Sepals oblong or obovate, obtuse, often reflexed, lateral sepals connate for a short distance at base. Petals linearobovate or oblong, obtuse, often reflexed. Labellum porrect, saccate, spurred, apex trilobed, midlobe much smaller than sac or spur; spur saccate, with a back wall callus, longitudinal septum, and usually a bilobed callus on front wall. Column variable, usually extended into a proboscis-like structure; pollinia four, as two unequal masses, stipe linear, viscidium ovate.
