. Common plants of longleaf pine-bluestem range. Plant ecology; Grasses; Forage plants. POOR-JOE Diodia teres Walt. Poor-joe, or rough buttonweed, is a slender an- nual. Although inconspicuous, it is usually present on longleaf pine-bluestem sites. Plants often grow abundantly on road shoulders, old fields, firelanes, and trails. The name refers to its commonness and abundance on badly depleted cropland. In competition with better range plants, poor-joe usually grows as scattered single stems about 4 inches long. In old fields and other heavily dis- turbed sites, plants branch profusely. They often form dense, low-growing colonies up to 4 feet in diameter. The opposite leaves are about 1 inch long and 3/16 inch wide. Small, tubular, white or pink- ish flowers are borne singly in leaf axils. Brown bristles about y± inch long form a cluster in each leaf axil. The clusters persist after fruit and leaves fall. Virginia buttonweed, Diodia virginiana L., is a spreading perennial common on poorly drained sites in central Louisiana. While cattle eat it readily, a prostrate habit enables plants to stand heavy grazing. A fleshy taproot permits survival during drought. Although its flowers and fruits resemble those of poor-joe, its leaves are elliptical and two to four times broader, though not longer. Where poor-joe is abundant, as on freshly burned range, cattle eat young plants along with grass herb- age. Toward maturity, palatability declines rapidly. Deer eat the foliage, and quail eat the seeds. Range: Texas to Florida, north to Kansas, Mich- igan, and Connecticut. Annual. Stems to 30 cm., pubescent, simple or branched, erect to spreading; leaves simple, opposite, entire, linear or linear-lanceolate, 1-4 cm. long, 2-3 mm. wide, scabrous; flowers solitary in upper leaf axils, four-merous; corolla white to pink, gamopetalous, 4-5 mm. long, calyx 2 mm. long, sepals acute; fruit a two- or rarely three-locular capsule 4-5 mm. long, individual carpels hard and P
