For small areas, newly in- fested, hand-pulling is a paying process. PARTRIDGE PEA Cdssia Chamcscrista, L. Other English name: Large-flowered Sensitive Pea. Native. Annual. Propagates by seeds. Time of bloom: July to September. Seed-time: September to November. Range: Massachusetts to Minnesota,. southward to the Gulf of Mexico. Habitat: Dry, sandy soil; fields, meadows, pastures, roadsides, and waste places; most troublesome in the Southwest. Pastures rankly infested with this weed are nearly useless, for it is strongly cathartic and when eaten in any quantity by cattle and sheep they "scour" very badly; grazing horses are sickened in the same way and must be relieved by change of forage. Young stalks are often mown and baled with the hay of infested meadows, causing the same trouble when the fodder is used in winter. The plant is low and spreading, often branching wider than its height of one or two feet. When young the stem may be sparsely hairy, but usually it is smooth and pale green. Leaves pin- nately compound, composed of ten to fifteen pairs of small, entire, lance- shaped leaflets each tipped with a sharp bristle; petioles short, with per- sistent, awl-shaped stipules and having near the base a sessile gland. The leaves are sensitive, and at night "go to sleep" by folding their blades. Pig. 158. â Partridge Pea {Cassia Chamcecrisia). X §â.
