Higher Taxonomy
Family: OrchidaceaeView DescriptionDichotomous Key

Habit: Perennial herb, terrestrial [growing on other pls], 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.
Genera In Family: +- 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. Note: Platanthera may be paraphyletic without inclusion of Piperia (Bateman et al. 2009 Ann Bot 104:431--445); study needed.

Genus: CypripediumView DescriptionDichotomous Key

Stem: often puberulent above. Leaf: cauline, lanceolate to ovate. Inflorescence: flowers 1--20; bracts +- leaf-like. Flower: lower sepals +- united [free], pendent behind lip; lateral petals downcurved to spreading, +- like upper sepal, twisted or not, lip pouch-like, generally obovoid, mouth +- puckered, margin inrolled; column curved over lip mouth, functional stamens 2, staminodes 1. Fruit: pendent to spreading, ribbed.
Species In Genus: +- 35 species: temperate North America, Eurasia; some cultivated for ornamental. Etymology: (Greek: Venus foot, from lip shape)
