This is the characteristic sort, often immensely abundant and found as far east as Colorado, often tinting the landscape for miles with its pale and beautiful foliage and one of the dominant shrubs in the Great Basin. It is very branching, from one to twelve feet high, with a distinct trunk and shreddy bark, and the twigs and alternate leaves are all gray-green, covered with silvery down, the upper leaves small and toothless, the lower wedge-shaped, with usually three, blunt teeth. The small yellow flowers have no rays and grow in small, close clusters, forming long sprays towards the ends of the branches. Sagebrush is a "soil indicator" and when the prospective rancher finds it on land he knows at once that it will be good for even dry farming, as the soil contains no salt or alkali.

There are a good many kinds of Eriophyllum, common and very variable, woolly plants.
