Description:
This is an herbaceous alliance dominated by <i>Carex helleri</i>, which often includes other species such as <i>Achnatherum nevadense, Achnatherum occidentale, Agoseris glauca, Antennaria media, Antennaria rosea, Arabis platysperma, Carex breweri, Carex filifolia, Carex subnigricans, Castilleja nana, Cistanthe monosperma, Draba densifolia, Elymus elymoides, Eriogonum incanum, Lupinus confertus, Luzula divaricata, Monardella odoratissima, Penstemon heterodoxus, Phyllodoce breweri, Poa suksdorfii, Raillardella argentea, Saxifraga tolmiei, Silene sargentii</i>, and <i>Trisetum spicatum</i>. Herbs and subshrubs are <80 cm in height, and the canopy cover is open to intermittent. Stands of this alliance occur primarily in California, in the alpine zones of the Sierra Nevada, east to the White and Inyo ranges, and into the southern Cascades and Klamath Mountains of California. Habitats are exposed upper slopes, ridges, and snowbeds at elevations of 2400-4100 m. Stands consist of scattered tufts of individuals in well-drained talus of cobble or gravel size. Deep snowpacks accumulate in these sites in winter, and may not melt until July or even August. Soils are well-drained gravely or sandy loams.
