Asclepias californica Greene
Habit: Perennial herb, dense-hairy. Stem: decumbent to +- ascending. Leaf: opposite; petiole short to 0; blade ovate. Inflorescence: terminal and at nodes; peduncle 0--3 cm. Flower: corolla reflexed, +- purple; hoods elevated above corolla base (generally northern California) or not (generally southern California), exceeded by anther head (but tops of hoods exceeding base of anther head), dark purple; horns 0 or minute, included in hood. Fruit: erect on +- reflexed pedicels. Seed: +- 1 cm.
Ecology: Flats, grassy or brushy hillsides; Elevation: 200--2100 m. Bioregional Distribution: c&s SNF, CW, SW, D; Distribution Outside California: northern Baja California. Flowering Time: Apr--Jul
Synonyms: Asclepias californica subsp. californica; Asclepias californica subsp. greenei Woodson
Unabridged Note: Asclepias californica Greene subsp. californica (hoods not elevated above corolla base; SW, D; northern Baja California) and Asclepias californica Greene subsp. greenei Woodson (hoods elevated above corolla base; central and southern SNF, CW) have been recognized elsewhere, and in fact many or most specimens may be assigned easily to one or the other. However, the number of specimens exhibiting morphological intergradation between the two, most of which evidently is not correlated with geog, precludes recognition here. The assertion by Woodson (1954, p. 178) that the subspecies have importance "phylogenetically," taken together with the foregoing, suggests that further investigation may be fruitful, or at least interesting.
