POINT REYES REIN-ORCHID

Higher Taxonomy
Family: OrchidaceaeView DescriptionDichotomous Key

Common Name: ORCHID FAMILY
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: PiperiaView DescriptionDichotomous Key

Common Name: PIPERIA
Habit: Plant 10--130 cm; tubers, 1--4 cm, generally +- round; stem bracts lance-linear to ovate. Leaf: at flower 0 or +- basal, not in rosette, 2--5, linear to widely oblanceolate. Inflorescence: spike or raceme, generally cylindric, flowers not in spiral; flower bract generally < flower. Flower: fragrance, when present, generally at night; perianth white to green; sepals generally 2--5 mm, 1--2 mm wide, 1-veined, upper pointed forward to erect, lower free, spreading to reflexed; lateral petals +- = sepals, spreading to erect, lip spurred, pointed forward, down (or upcurved); column < lip; ovary inferior, generally twisted 180°. Fruit: ascending to erect.
Species In Genus: 10 species: North America. Etymology: (Charles V. Piper, American botanist, 1867--1926) Note: Some species difficult to separate.
