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]
