Perennial herb, terrestrial [growing on other plants], non-green (nutrition from association of roots with fungi) or green, generally from rhizomes or tubers with few to many fleshy to slender roots; cauline leaves ± reduced to sheathing stem bracts or not. Leaf: 1–many, basal to cauline, linear to ± round, alternate to opposite (if only 1 pair), generally sessile. Inflorescence: flowers 1–many, spike or raceme, bracted. Flower: bisexual, bilateral, in bud generally rotating 180° by twisting ovary (position of parts indicated after twisting); sepals generally 3, generally free, generally petal-like, uppermost generally erect, lateral with chin- or spur-like projection (mentum) or not; petals 3, 1 (lip) different, spurred or not; stamens generally 1 (3 in Cypripedium, 2 functional, 1 a staminode), fused with style, stigma into column, pollen generally lumped, generally removed as unit by insect; ovary inferior, 1-chambered, placentas 3, parietal, stigma 3 lobed, generally under column tip. Fruit: capsule. Seed: many, minute.
± 800 genera, ± 25000 species: especially tropics (worldwide except Antarctica). Many cultivated for ornamental, especially Cattleya, Cymbidium, Epidendrum, Oncidium, Paphiopedilum; Vanilla planifolia Andrews fruits used to flavor food. [Romero-Gonzalez et al. 2002 FNANM 26:490–651] Platanthera may be paraphyletic without inclusion of Piperia (Bateman et al. 2009 Ann Bot 104:431–445); study needed. —Scientific Editors: Ronald A. Coleman, Thomas J. Rosatti.
