Shirley Meadows Star-tulip

Calochortus westonii, common name Shirley Meadows star-tulip, is a rare endemic plant known only from the Greenhorn Mountains range of the southern Sierra Nevada, within Kern and Tulare Counties, California.

It grows in open locations in meadows and woodlands at elevations of 1,500–2,000 m (4,900–6,600 ft). It is vulnerable due to habitat loss from logging, development of ski resort, and fuel breaks.
