California's native perennial grasses have been largely replaced by alien annuals. Interest in restoration of native grasslands is strong, but genetic differences among the available collections of some grasses may affect the survival of plantings and remnant native stands. In collections of the four native grasses examined, differences in phenology, growth form and forage quality suggest the existence of geographic races.
