Description

Allium yosemitense grows from a bulb two to three centimeters long, producing a scape up to about 23 centimetres (9.1 in) in maximum height. It has two long flat leaves that are usually slightly longer than the scape. The umbel contains up to 50 white or pink flowers, each on a pedicel which may be over 3 centimetres (1.2 in) long.[1][2][3]
Distribution and habitat

Allium yosemitense is endemic to the central Sierra Nevada of California. Populations have been recorded in three counties: El Dorado, Mariposa and Tuolumne. Most of the sites are inside Yosemite National Park.[1][4][5][6]

The habitats in which Allium yosemitense can be found include: California interior chaparral and foothill woodlands, Sierra Nevada lower montane forest (Yellow Pine Forest), Mediterranean California Lower Montane Black Oak-Conifer Forest (Mixed Evergreen Forest).[1]

Allium yosemitense is listed by the State of California as Rare, and included in the California Native Plant Society—CNPS Inventory of Rare and Endangered Plants of California.[7]
