Nuttall's Horsebrush-Tetradymia nuttallii

Decorating the lower foothills are bushes with bright yellow flowers. It's too early for rabbitbrush; these bushes are horsebrush (Tetradymia), also in the Sunflower Family (Asteraceae). We have four species in this area, and from what I can figure out, this one is Nuttall's horsebrush (Tetradymia nuttalli).

There are short thorns on the plant and it grows below 6,400 feet. It is found in Nevada, Utah, Wyoming, and Colorado.

For more information about Nuttall's Horsebrush--there really isn't much on the Internet, click here to visit the USDA fire effects information website.
