ONAGRACEAE

EVENING PRIMROSE FAMILY

Warren L. Wagner, except as specified Peter H. Raven, Family Coordinator

Annual to tree
Leaves basal or cauline, alternate, opposite, or whorled, generally simple and toothed (to pinnately compound); stipules 0 or generally deciduous
Inflorescence: spike, raceme, panicle, or flowers solitary in axils; bracted
Flower generally bisexual, generally radial, opening at dawn or dusk; hypanthium sometimes prolonged beyond ovary (measured from ovary tip to sepal base); sepals generally 4(2–7); petals generally 4 (or as many as sepals, rarely 0), often "fading" darker; stamens generally 4 or 8(2), anthers 2-chambered, opening lengthwise, pollen generally interconnected by threads; ovary inferior, chambers generally 4 (sometimes becoming 1), placentas axile or parietal, ovules 1–many per chamber, style 1, stigma 4-lobed (or lobes as many as sepals), club-shaped, or hemispheric
Fruit: capsule, loculicidal (sometimes berry or indehiscent and nut-like)
Seeds sometimes winged or hair-tufted
Genera in family: 15 genera, ± 650 species: worldwide, especially w North America; many cultivated (Clarkia, Epilobium, Fuchsia, Gaura, Oenothera )
Reference: [Munz 1965 North America Fl II 5:1–278]

CAMISSONIA

SUN CUP

Annual, perennial herb, from taproot or lateral roots
Leaves basal, cauline, or both, alternate, simple to 2-pinnate
Inflorescence bracted; spike, raceme, or flowers solitary in axils
Flower radial, generally opening at dawn (rarely at dusk); sepals 4, reflexed (sometimes 2–3 remaining adherent); petals 4, yellow, white, lavender, often with darker basal spots, generally fading purplish or reddish; stamens (4)8, longer ones opposite sepals, anthers generally attached at middle (or base), pollen grains 3-angled except in polyploid taxa (visible with hand lens); ovary chambers 4, stigma ± head-like or hemispheric, generally > anthers and cross-pollinated (or ± = anthers and self-pollinated)
Fruit straight to coiled, generally sessile
Seeds in 1–2 rows per chamber
Species in genus: 62 species: w North America (especially CA-FP), 1 South America
Etymology: (L.A. von Chamisso, French-born German botanist, 1781–1838)
Reference: [Raven 1969 Contr US Natl Herb 37:161–396]
Polyploidy and self-pollination have predominated in evolution of genus. Previously included in Oenothera (" O." in synonyms).

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).
