Indian ricegrass (Oryzopsis hymenoides) and cheatgrass (Bromus tectorum) seedlings often emerge from rodent caches in sandy habitats in the Great Basin (La Tourette et al., 1971; McAdoo et al., 1983).
Quality and germinability of Oryzopsis hymenoides seed in Lahontan sands.
Several perennial grasses, including needle-and-thread (Stipa comata), Indian ricegrass (
Oryzopsis hymenoides) and bluegrass (Poa spp.) and one annual grass, cheatgrass (Bromus tectorum), are the dominant understory plants.
In the shrub-grassland area where soils are coarsely textured, the saltbush is more widely spaced and there are numerous small shrubs (Artemisia frigida, Eriogonum effusum, Gutierrezia sarothrae, Chrysothamnous nauseous, Ceratoides lanata) and perennial bunch-grasses (Stipa comata,
Oryzopsis hymenoides, Aristida longiseta, Sitanion hystrix).
