Areas infested with this annual should be grazed early or mowed before the heads appear. Although a strong seed producer, mouse barley tends to be re- placed under proper range use by the better forage Fig. 61. Mouse barley (Hordeum leporinum). 4. MEDITERRANEAN BARLEY (Hordeum hystrix) is a weedy branching annual, geniculate at base, mostly 6-12 in (15- 30 cm) tall; foliage more or less pubes- cent; spike cm long, the axis tardily breaking up; glumes setaceous, rigid, about 12 mm long; sterile florets reduced. Fields and waste places. Mediterranean barley has a wide dis- tribution (fig. 58) and is fairly abundant in some local areas. The young herbage is taken with associated forage plants, but the plant matures early and is then utilized but little. 15. RYEGRASSES (LOLIUM) Ryegrasses are rather slender erect short- lived leafy perennials or annuals, with slender flat spikes; spikelets placed edge- wise on the rachis, not overlapping. Two old-world ryegrasses, perennial ryegrass and Italian ryegrass, occur com- monly in California and provide desir- able forage. Introduced from Europe, they are now common in the interior valleys and on the foothill ranges of the coast. Key to Species Glumes as long or longer than the spikelets 3.
