Indian Ricegrass 

(Oryzopsis hymenoides) 

Indian rice grass has a wide distribution, mainly at medium eleva- 
tions in the mountains and intermountain basins of western North 
America. In New Mexico it is found from the southern desert area, 
throughout the western plateau and northern desert up to various 
Rocky Mountain sites. It is found in all soil types, but it seems to prefer 
coarser textured soils in the lower, more arid portions of its range. 
Indian rice grass is highly palatable to all classes of livestock. It is readily 
consumed at all times of the year but has its greatest value in the 
spring, when it supplies nutritious green feed before most other natives 
make much growth. It is also one of the most drought resistant rangegrasses. The plants show a tendency to be short-lived and must re-produce by seed if any quantity is to be maintained on the range. There is a wide variation in seed dormancy and rate of growth 
depending on place of collection. Some collections require a full year 
of stratification while others will germinate if planted two months prior 
to the time the seed should emerge from a depth of 7.5 to 10 cm. (3 to 4 in.). If planted as a single species, it is recommended that the seed be placed 2.5 to 5 ern (1 to 2 in.) deep. Planting should be just before the advent of winter moisture, but may range from late fall to mid-February.

Nezpar was released by the USDA Soil Conservation 
Service. It was selected for its unusually low percen- 
tage of hard seeds and excellent seedling vigor. It is recommended for use throughout the intermountain area of the West. 



Paloma Indian rice grass was released in 1974 by the Agricultural Experiment Stations of New Mexico State University and Colorado State University, the University of Arizona, the New Mexico State Highway Department and the USDA Soil Conservation Service. The Paloma seed was originally collected from a native stand west of Pueblo, Colorado. Mature Paloma seed are brown to black with a fringe of dense hair surrounding each. The seed of this variety, though not completely round, are less elongated than many of the northern strains. 
Paloma is well suited for soil stabilization and revegetation of rangelands in areas of low precipitation, such as in strip mining operations of theFour-Corners areas of New Mexico, Arizona, Utah and Colorado.Besides being valuable as a livestock feed; birds,especially mourning doves, pheasants, and small rodents relish the plump,nutritious seed.
