BRODIAEA

J. Chris Pires & Robert E. Preston


Daughter corms often present. Leaf: generally 1–6, linear, generally crescent-shaped in ×-section, glabrous, entire, often withered at flower. Inflorescence: open; scape 2–70 cm, generally slender, generally straight, cylindric; bracts scarious; pedicels generally > flowers, generally < 13 cm. Flower: perianth tube bell- to funnel-shaped, green-white, lobes erect to spreading, violet to lavender, occasionally pink, midribs purple or green; staminodes (0)3, generally ± erect, opposite outer lobes, white to violet or lavender, lateral margins flat, incurved, or inrolled; stamens 3, equal, fused to perianth, opposite inner lobes, filaments occasionally winged or appendaged, free or fused basally to staminodes, generally not forming crown-like tube, anthers attached at base, appressed to style, abaxially papillate; style 1, stigma lobes 3, spreading and recurved. Fruit: sessile, ovoid. Seed: oblong, black, lined, angles ridged.
± 18 species: mostly endemic to California. (James Brodie, Scottish botanist, 1744–1824) [Preston 2006 Novon 16:254–259] Several undescribed taxa, hybrids under study. Brodiaea matsonii R.E. Preston described from Shasta Co., 2010.
