}} ''Oryzopsis hymenoides'' (Synonym: ''Stipa hymenoides'', Common name: Indian ricegrass) is a perennial cool-season bunchgrass with very narrow, rolled leaf blades.〔Mojave Desert Wildflowers, Pam MacKay, 2nd Ed., p287〕 It is native to western North America east of the Cascades from British Columbia and Alberta south to southern California, northeastern Mexico, and Texas. In the wild it typically grows 4 to 24 inches (10 to 61 cm) tall and 8 to 12 inches (20 to 30 cm) wide.〔Tirmenstein, D. 1999. (Achnatherum hymenoides ). In: Fire Effects Information System, (). U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station, Fire Sciences Laboratory (Producer). Retrieved on 2009-04-24.〕 ''Oryzopsis hymenoides'' grows in a variety of habitats from desert scrub up to ponderosa pine forests. It can live in soils from sand to clay, but it does particularly well in sand, where it is the dominant grass growing with sagebrush and may occur almost unmixed with other plants.〔 It helps stabilize shifting sand.〔Canyon Country Wildflowers, Damian Fagan, 2nd ed., 2012, Morris Bush Publishing, LLC. in cooperation with Canyonlands Natural History Association, ISBN 978-0-7627-7013-7〕 ==Cultivation== Indian ricegrass is an important food for livestock and for wild grazers such as bison, desert bighorn sheep, elk, mule deer, pronghorns, and jackrabbits. For some of these species it is especially vital in late winter, as it produces green shoots earlier than other grasses. The seeds are heavily consumed by many rodents and birds, notably mourning doves.〔 This tough grass is known for its ability to reseed and establish itself on sites damaged by fire or overgrazing. Much germination occurs in years with wet Aprils. It is grown in xeriscapes—cultivars are available—and will become quite large if given sufficient space. The open, spangled appearance when in flower or fruit is very attractive, especially in backlight. The flower stalk is commonly used in dry flower arrangements.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「oryzopsis hymenoides」の詳細全文を読む スポンサード リンク
