Comments:Stands of this once extensive series now typically include non-native, annual species mixed with native perennial grasses and herbs. Ripgut, soft chess, and foxtail chess are common as are slender oats, wild oats, and Italian ryegrass. Foothill needlegrass, nodding needlegrass, and purple needlegrass may occur sympatrically, but they do not typically mix, especially in SoCo. They tend to segregate based on substrate and slope factors [ s Foothill needlegrass series, Purple needlegrass series]. In the ecological literature nodding needlegrass is referred to as Stipa cernua . The Jepson Manual places nodding needlegrass in the genus Nassella .
Plot based descriptions:Keeler-Wolf (1989a) describes blue oak stands with a high cover of nodding needlegrass at Wagon Caves candidate RNA in Monterey Co. o-CenCo; Kellogg & Kellogg (1990, 1991) present unclassified plot data for areas dominated by foothill needlegrass, noddi g needlegrass, or purple needlegrass at Pendleton Marine Corps Base in San Diego Co. o-SoCo.
