| Description | Habitat: Common on rocky, chalky or sandy soils in North Central Texas and on the Edwards Plateau. Plant: Trailing, prostrate, branched perennial, stems 12 to 40 inches long with recurved (bent-back) prickles; lower portion of stem rounded. Leaves: Bi-pinnately compound on prickly stalks with 2 to 6 pairs of primary leaflets divided into several pairs of small secondary leaflets that fold up when disturbed; each leaflet is smooth beneath (no conspicuous midrib and sideribs). Inflorescence: Dense pink, ball-shaped inflorescence 3/4 to 1 inch in diameter with many very small individual flowers each with 5 petals and 8 to 12 protruding stamens with pink filaments and yellow anthers. Bloom Period: April to June. Fruit: Mature fruit noticeably flattened, 3 to 6 times wider than thick. References: Shinners & Mahler's Illustrated Flora of North Central Texas pp. 677-682 and www.wildflower.org. Note: Leaflets are sensitive to touch and will fold up when disturbed. Very similar to M. nuttallii, except for lack of conspicuous midribs on leaflets, rounded stems and fruit shape. |
