Camissoniopsis cheiranthifolia subsp. suffruticosa |
Onagraceae subfam. onagroideae |
|
Phenology | Flowering Jan–Aug. | |
Habitat | Coastal sandy slopes, dunes, and flats. | |
Elevation | 0–100 m. (0–300 ft.) | |
Distribution |
CA; Mexico (Baja California) |
North America; Mexico; Central America; South America; West Indies; Eurasia; Pacific Islands (New Zealand, Society Islands); Australia |
Discussion | Subspecies suffruticosa occurs from near Goleta, Santa Barbara County, California, and San Nicolas Island, south to near San Quintín and Isla San Martín, Baja California, Mexico (P. H. Raven 1969). The subspecies hybridizes with C. bistorta in areas of near sympatry. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Genera 21, species 582 (16 genera, 246 species in the flora). Onagroideae encompass the main lineage of the family, after the early branching of Ludwigia (R. A. Levin et al. 2003, 2004). This large and diverse lineage is distinguished by the presence of a floral tube beyond the apex of the ovary; sepals deciduous with the floral tube, petals, and stamens; pollen shed in monads (or tetrads in Chylismia sect. Lignothera and all but one species of Epilobium); ovular vascular system exclusively transseptal (R. H. Eyde 1981); ovule archesporium multicellular (H. Tobe and P. H. Raven 1996); and change in base chromosome number from x = 8 in Ludwigia to x = 10 or x = 11 at the base of Onagroideae (Raven 1979; Levin et al. 2003). Molecular work (Levin et al. 2003, 2004) substantially supports the traditional tribal classification (P. A. Munz 1965; Raven 1979, 1988); tribes are recognized to delimit major branches within the phylogeny of Onagroideae, where the branches comprise strongly supported monophyletic groups of one or more genera.
