Calochortus pulchellus
Calochortus pulchellus is a rare species of flowering plant in the lily family known by the common name Mt. Diablo fairy-lantern or Mount Diablo globelily.[3][4] Calochortus pulchellus is endemic to California, where it is mainly restricted to Mount Diablo of the Diablo Range, in Contra Costa County of the eastern San Francisco Bay Area.[5] There are historical occurrences in the North California Coast Ranges, within Marin, Solano, Napa, and Humboldt Counties.[4] It grows in chaparral and woodland habitats, currently only known on the bayside−western slopes of Mount Diablo.[5] DescriptionCalochortus pulchellus is a perennial herb growing a branching stem up to about 30 centimeters tall. The basal leaf is up to 40 centimeters long and does not wither at flowering; there are 2 or 3 smaller leaves higher up the stem.[5] The inflorescence is a solitary flower or a cluster of several flowers, which are nodding and usually spherical with all their petal tips touching. The three sepals and three petals are 2 or 3 centimeters long and pale to deep yellow. The petals are thinly hairy inside and often fringed with yellow hairs.[5] The fruit is a winged capsule 2-3 centimeters in length.[5]
