Description: Blackbrush - Coleogyne ramosissima Torr. - grows in the transition zone between warm and cold deserts of southern California, southern Nevada, southern Utah, northern Arizona, and southwestern Colorado. It is found at elevations of 760 to 1,980 m. Ranging from 0.3 to 1.2 m in height, blackbrush forms almost monotypic stands in the lower Mojave-Great Basin ecotone, bounded by creosote bush (Larrea tridentata (Sesse & Moc.) ex DC. Coville.) communities at low elevations and by juniper-big sagebrush (Artemesia tridentata Nutt.) communities at higher elevations. In the eastern part of its range, blackbrush is bordered by Sonoran communities on the south and by big sagebrush, juniper, and mixed shrub communities of the Colorado Plateau in the north. Distribution of blackbrush is limited by soil depth, temperature extremes, and moisture availability.
