Vernacular names

Allium coryi, common name yellowflower onion, is a plant species endemic to trans-Pecos Texas, but sometimes cultivated as an ornamental elsewhere. It is reported in the wild from only five counties: Brewster, Presidio, Jeff Davis, Pecos and Terrell. Some of the populations lie inside Big Bend National Park.[2][3]

Allium coryi grows on rocky slopes and plains at elevations of 800–1400 m. It produces egg-shaped bulbs up to 2 cm long. Flowers are bright yellow, up to 10 mm across; anthers and pollen are yellow.[2][4][5][6]
