Perennial, terrestrial in CA, some nongreen, generally from rhizomes
Leaves linear to ± round or scale-like, generally sessile
Inflorescence: generally raceme or spike, bracted
Flower bisexual, bilateral, sometimes spurred; sepals generally 3, generally petal-like, generally free, uppermost generally erect; petals 3, lowest different ("lip"); stamen generally 1, fused with style and stigma into column, pollen generally sticky, generally removed as sessile anther sacs; ovary inferior, generally twisted 180° (so lip appears to be lowest perianth segment), 1-chambered, placentas 3, parietal; stigmas 3, generally under column tip
Seeds very many, minute
Genera in family: ± 800 genera, ± 18,000 species: especially tropical (worldwide except deserts). Many cultivated for ornamental, especially Cattelya, Cymbidium, Epidendrum, Oncidium, Paphiopedalum; Vanilla planifolia fruits used as source of food flavoring
