See text Lasthenia, commonly known as goldfields, is a genus of flowering plants family Asteraceae.

The genus is named after Lasthenia of Mantinea, a cross-dressing female pupil of the ancient Greek philosopher Plato.

The goldfield genus comprises annual (rarely perennial) herbs that are either glabrous or hairy.

[1] Goldfield species occur over a range of habitat, such as meadows, shrubland and open forest, but tend towards semiarid conditions.

They are visited by Sciaridae fungus gnats for nectar, and it is possible that these animals are key pollinators at least for Contra Costa Goldfields (L. conjugens).
