. California grasslands and range forage grasses. Grasses; Forage plants. the other pediceled, staminate or empty, 1 to 5 pairs in short racemes, these borne on the branches of a compound panicle; perfect spikelets about 5 mm long, plump, with a delicate bent awn about 1 cm long, readily falling; rachis joints and pedicels short-hairy. (Fig. 111.) Distribution and habitat: Johnson- grass is an aggressive perennial with strong rhizomes that has become a seri- ous pest in many agricultural areas of California. It grows over a wide range of soil and moisture conditions, but is most abundant on cultivated areas. Forage value and reproduction: The leafage is relished by all classes of live- stock. As a forage plant Johnsongrass suffers by becoming sodbound when the soil is not occasionally stirred. Heavy grazing by hogs who relish the rhizomes is sometimes used as a control measure on badly infested fields. Under certain conditions Johnsongrass causes hydro- cyanic poisoning. Young plants are more toxic than mature ones, especially when growth is interrupted, as by frost or drought (45). Johnsongrass makes pal- atable hay, and when fed as such causes no poisonous effects. Reproduction is vigorous by means of rhizomes, yet a large amount of good seed is produced. Fig. 111. Johnsongrass (Sorghum halepense). [115].
