| Lasthenia burkei is a herbaceous annual with narrow leaves and produces small clusters of whitish-yellow flowers. This aster grows in vernal pools and swales in Cotati Valley in Sonoma County, California. Vernal pools, one of California's most threatened habitats, are natural depressions that fill with water during the winter and spring and dry up during the summer. Plants that live in the vernal pool ecosystem are specifically adapted to ephemeral ponds. Like other vernal pool plants, Lasthenia burkei germinates during the flooding period and blooms as the pools dries. Urbanization, agriculture and widening along Highway 101 have negatively impacted this species in Sonoma County. Lasthenia burkei was placed on the endangered species list in 1991 (USFWS 1992).
