Description
Family Onagraceae
Annual
or perennial
herbs, or shrubs
, rarely trees
to 30 m
tall, often with epidermal oil cells
, usually with internal phloem
. Leaves simple
, spirally arranged
, opposite, or occasionally whorled
, entire or toothed
to pinnatifid
; stipules present and usually caducous
, or absent. Flowers perfect
and hermaphroditic
or occasionally unisexual
, actinomorphic
or zygomorphic, (2-) 4(-7) -merous, axillary
, in leafy spikes or racemes
or solitary, or occasionally in panicles, all but Ludwigia with distinct
floral tube
, nectariferous
within. Sepals green or colored
, valvate
. Petals as many as sepals or rarely absent, variously colored, imbricate or convolute and occasionally clawed. Stamens as many as sepals in one series or 2 × as many as sepals in 2 series [in Lopezia Cavanilles reduced to 2 or 1 plus 1 sterile
staminode]; anthers
versatile or basifixed
, dithecal
, sometimes cross-partitioned, opening by longitudinal
slits; pollen grains
almost always united
by viscin threads, shed as monads
, tetrads
, or polyads
. Ovary inferior, with as many carpels and locules as sepals, septa sometimes thin or absent at maturity; placentation axile
or parietal
, ovules 1 to many per locule, in 1 or several rows
or clustered, anatropous
, bitegmic; style 1; stigma with as many lobes
as sepals or clavate
to globose
. Fruit a loculicidal capsule or indehiscent nut or berry. Seeds small, smooth
or variously sculptured
, sometimes with a coma [or wing], with straight oily embryo, endosperm lacking.
Seventeen genera and ca.
650 species: widespread in temperate
and subtropical
areas, but best represented in W North America; six genera (two introduced
), 64 species (11 endemic, 11 introduced), and five natural hybrids (two endemic) in China.
Onagraceae are a well-defined, monophyletic family
in the order
Myrtales, with a sister relationship
to Lythraceae. Within the order Myrtales, the Onagraceae are distinguished by a number of features including (1) a distinctive 4-nucleate embryo sac; (2) abundant raphides
in vegetative cells
; (3) paracrystalline beaded pollen ektexine; and (4) pollen with viscin threads.
Some species of Oenothera are grown for the oil
in their seeds, which contains gamma linolenic acid (GLA), used for medicinal purposes. Several species of Onagraceae also are cultivated in China for their horticultural value, including species of Fuchsia Linnaeus (generally distinguished by having large, tubular
, red or orange flowers and fleshy
berries
) and Clarkia Pursh (distinguished by having stigmas with commissural
lobes with dry, unicellular papillae, and dry, elongate
capsules similar to those of Epilobium but lacking comas on the seeds) . The most commonly cultivated Fuchsia is F. ×hybrida Hort. and the related F. magellanica Lamarck in F. sect. Quelusia (Vandelli) Candolle from South America; F. triphylla Linnaeus, in F. sect. Fuchsia, from Hispaniola, is known from only one gathering in Fujian. Similarly, Clarkia amoena (Lehmann) A. Nelson & J. F. Macbride is widely cultivated in China, whereas C.
pulchella Pursh is known from only one gathering in Xizang; both species are native
to W North America. There are no naturalized
species of either Clarkia or Fuchsia in China.[1]
