I took the pictures of Eriogonum corymbosum var. nilesii in the far north of Las Vegas suburb: 36°18’54” N / 115°11’30” W, north of Horse Drive and adjacent to the McCool Regional Park. Unfortunately, my camera was out of sync and my pictures were totally solarized. I will need to go back there unless I find this variety in the Mohave Desert.

Flowering Aug-Nov. Sandy to gravelly or gypsum flats and washes, saltbush communities; 200–900 m; Mojave Desert in the Las Vegas and Muddy Mountains region of Clark Co., southern Lincoln Co., Nevada, and in the Fort Pierce Wash area of Mohave Co., Arizona.
