MALVACEAE (MALLOW FAMILY) 279 high, erect, much branched, downy-hairy. Leaves alternate, one to two inches long, ovate to lance-shaped, scallop-toothed, downy-hairy, with base rounded or abruptly narrowed to petioles abo,ut half as long as the blades; at the base of some of the larger leaves is a small, pointed tubercle, which gives the plant its name though it is hardly long enough or sharp enough to be called a spine. Flowers light yellow, only about a quarter-inch broad, on short axillary peduncles; calyx with five teeth, shorter than the obovoid petals; styles five with undi- vided stigmas, surrounded by united sta- mens. Fruit ovoid, containing five carpels, each splitting at the top into two beaks. Seeds triangular, smooth, dark brown. (Fig. 195.) Means of control Deep hoe-cutting while in early bloom. Mowing the plants leaves stubs, which hasten to produce new stalks and require atten- F^6^S^Sf* tion a second time; but deep cutting PAROQUET BUR (Sida, acuta, Burm.) (Sida stipul&ta, Cav.) Native. Annual or perennial. Propagates by seed. Time of bloom: June to November. Seed-time: July to December. Range: The Gulf States from Florida westward. Habitat: Cultivated crops, pastures, roadsides, and waste Sheep are grown in the South more for mutton than for fleece, but the value of the latter is annually damaged to a large amount by the hooked carpels of this weed, the distribution of which is almost entirely due to animal Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Georgia, Ada Eljiva, 1859-1921.
