Lasthenia glabrata
Lasthenia leptalea
Subspecies 2 (2 in the flora).
Historically, aboriginal Californians used fruits and leaves of Lasthenia glabrata for food. The subspecies are allopatric and almost identical except for their cypselae.

Lasthenia leptalea grows in southern Monterey and northern San Luis Obispo counties. Originally assigned by R. Ornduff (1966b) to sect. Burrielia, L. leptalea is morphologically similar to L. gracilis, from which it can be distinguished by its subulate anther appendages and phyllaries that are hairy only at their tips.
