CANARYGRASS {PHALARIS) Leafy annuals or perennials, with dense panicles; spikelets with 1 terminal perfect floret and 2 (rarely 1) scalelike sterile lemmas below, these falling attached to the mature floret; glumes keeled, often winged on the keel, longer than the floret; fertile lemma coriaceous, laterally com- pressed. Key to Species Plants annual; spikelets in clusters falling entire; glumes of outer spikelets club-shaped 3. P. paradoxa var. praemorsa Plants perennial; glumes persistent on the pedi- cels, none club-shaped Panicle ovoid, about 2 cm thick; spikelets 6-8 mm long 2. P. californica Panicle cylindric, mostly 6-15 cm long, cm thick; spikelets 5-6 mm long 1. P. tuberosa var. stenoptera {Phalaris tuberosa var. stenoptera) is perennial from strong loosely branching rhizomes; culms stout, 2V2-41/2 ft (75-150 cm) tall, very leafy, blades 5-10 mm wide; panicles 5-15 cm long; glumes 5-6 mm long; fertile lemma 4 mm long, with but 1 minute sterile lemma. (Fig. 105C) Distribution and habitat: Harding- grass is an introduced perennial that has been found suitable for reseeding Cali- fornia brush ranges and retired grain- fields (36, 51). It thrives best on heavy black soils and on deep volcanic loams, but will produce well on lighter soils underlaid by heavier strata (31, 32). Forage value and reproduction: The large dense leafy tufts are relished by all classes of livestock. Hardinggrass is one of the few perennials to make good growth in winter when most other plants are dormant. It produces f
