Clarkia concinna
Onagraceae tribe Onagreae
red ribbons
erect, to 40 cm, glabrous or puberulent.
petiole 5–25 mm;
blade lanceolate to elliptic or ovate, 1–4.5 cm.
alternate or basal;
stipules absent.
racemes, axis suberect or slightly recurved;
buds pendent.
floral tube 13–25 mm;
sepals reflexed together to 1 side, sometimes nearly separating, petal-like, pink or red;
corolla rotate, petals bright pink, usually white-streaked, narrowly fan-shaped, 10–30 mm, length 2 times width, tapered to a ± distinct claw, lobes ± equal or middle lobe wider, usually oblanceolate;
stamens 4, filaments not wider distally;
ovary 8-grooved;
stigma exserted or not beyond anthers.
usually actinomorphic, rarely slightly zygomorphic (in Oenothera), (3 or)4-merous;
stamens 2 times as many, or rarely as many, as sepals;
pollen usually shed in monads, rarely tetrads (Chylismia sect. Lignothera).
a dry capsule, usually dehiscent, sometimes indehiscent.
15–20 mm;
sessile.
reddish brown, 2–3 mm, scaly, crest to 0.8 mm, conspicuous.
few to numerous, without hairs or wings, [very rarely with asymmetrical dry wing (Xylonagra)], or with dry (Oenothera), erose or smooth wing, or with thick, papillate wings (Chylismiella).
Clarkia concinna
Onagraceae tribe Onagreae
Subspecies 3 (3 in the flora).
The two self-pollinating subspecies with smaller flowers probably arose independently from the outcrossing subsp. concinna.

Genera 13, species 265 (12 genera, 199 species in the flora).
Onagreae account for more than half the total genera in Onagraceae and diversified from a center in southwestern North America (L. Katinas et al. 2004). Delimitation of the tribe by W. L. Wagner et al. (2007) differs from previous ones by the exclusion of Gongylocarpus, now in its own tribe, by the segregation of eight genera (Camissoniopsis, Chylismia, Chylismiella, Eremothera, Eulobus, Neoholmgrenia, Taraxia, and Tetrapteron) from Camissonia, and by the inclusion of three previously separate genera (Calylophus, Gaura, and Stenosiphon) in Oenothera. Within the branch of the family that lacks stipules (Gongylocarpeae, Epilobieae, and Onagreae), the last two tribes form a clade that has very strong molecular support (R. A. Levin et al. 2003, 2004), but no obvious morphological synapomorphy. The clade may be defined by a cytogenetic change from the base chromosome number of x = 11 found in Circaeeae, Gongylocarpeae, and Lopezieae, to x = 18 in Epilobieae, and x = 7 in Onagreae; however, these changes could also have occurred independently. Other than the new chromosome number x = 7, the only apparent morphological synapomorphy for Onagreae alone is pollen with prominent apertural protrusions (J. Praglowski et al. 1987, 1989), a character state also found in Circaeeae (Praglowski et al. 1994). The monophyly of Onagreae has moderate (Levin et al. 2004) to strong support (V. S. Ford and L. D. Gottlieb 2007).
