NEED IN SITU PHOTOS. Littleseed ricegrass has been often collected in the Watershed, a common grass of foothill and montane pinyon and juniper slopes. Piptatheropsis macrantha is a perennial and can be found growing under ponderosa, spruce, juniper, and especially pinyon. On more open ground it frequents rocky slopes with volcanic substrate and igneous outcrops, sometimes along roadsides. The Lower Basin collections come from the San Luis Hills or mesas. The USA distribution is the desert Southwest, the Intermountain region, and the Rocky Mountains from the Canadian border to the Mexican. It follows the Rio Grande drainage through New Mexico to the southwestern tip of Texas.
