ORCHIDACEAE

ORCHID FAMILY

Dieter H. Wilken and William F. Jennings

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
Fruit: capsule
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
Reference: [Luer 1975 Orchids US and Can, NY Bot Garden; Coleman 1995 Wild Orchids of California, Cornell Univ.]
Nongreen plants derive nutrition through fungal intermediates.

CYPRIPEDIUM

LADY'S-SLIPPER


Stem leafy, often puberulent above
Leaves: basal 1–2, < cauline; cauline lanceolate to ovate, often ribbed
Inflorescence: flowers 1–several; bracts ± leaf-like
Flower: lower sepals ± fused, pendent behind lip; lateral petals descending to spreading, ± like upper sepal, sometimes twisted; lip balloon-like, generally obovoid, mouth ± puckered, margin inrolled; column curved over lip mouth; stamens 2, separated by petal-like staminode
Fruit pendent to spreading, ribbed
Species in genus: ± 35 species: temp North America, Eurasia
Etymology: (Greek: Venus foot, from lip shape)
Some cultivated for ornamental.

Native

YOU CAN HELP US make sure that our distributional information is correct and current. If you know that a plant occurs in a wild, reproducing state in a Jepson bioregion NOT highlighted on the map, please contact us with that information. Please realize that we cannot incorporate range extensions without access to a voucher specimen, which should (ultimately) be deposited in an herbarium. You can send the pressed, dried collection (with complete locality information indicated) to us (e-mail us for details) or refer us to an accessioned herbarium specimen. Non-occurrence of a plant in an indicated area is difficult to document, but we will especially value your input on those types of possible errors (see automatic conversion of distribution data to maps).
