Lasthenia glabrata
Lasthenia microglossa
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.

Because the rays are inconspicuous, plants of the self-pollinating Lasthenia microglossa are easy to overlook. Besides growing in habitats similar to those occupied by L. debilis, L. microglossa is found also beneath chaparral shrubs and extends into desert areas, where it grows near rocks that may provide favorable shade and moisture conditions.
