Annuals. Leaves ± entire or toothed (not pinnatifid). Involucres campanulate to cylindric. Phyllaries falling with cypselae, distinct. Receptacles subulate, papillate, glabrous. Ray corollas yellow, laminae 0–1 or 3–5 mm, floral pigments turning deep red in dilute aqueous alkali. Disc corolla lobes 4–5; anther appendages subulate or deltate (with 1–4 wartlike glands in L. debilis); style apices lanceolate and glabrous, or ± deltate with apical tufts of hairs and subapical fringes of shorter hairs. Cypselae to 5 mm; epappose or pappose. 2n = 8, 24.
Discussion
Species 2 (2 in the flora).
Within Lasthenia, only members of sects. Amphiachaenia and Burrielia have floral anthochlor pigments that turn red in aqueous alkali. Unlike most lasthenias, the two members of Lasthenia sect. Burrielia are inconspicuous and usually occur in relatively moist, shaded woodland areas. Both have relatively thick stems, relatively broad, obscurely toothed leaves, relatively few rays, phyllaries that fall with cypselae, and similar induments.
Selected References
