Stem one to three feet tall, stout, four-sided, swollen below the joints, much branched and spread- ing, bristling with prickly hairs. The opposite leaves are ovate, long- pointed, coarsely toothed, bristly- hairy on both sides, and with bristly petioles. Flowers in a dense, short, leafy-bracted terminal spike and in axillary clusters; corolla nearly an inch long, pink or pale purple, with a stiff, concave entire upper lip, longer than the lower one, which has three lobes; the tube is about twice the length of the bristly calyx, which has five long, nearly equal awl-like points. Seeds four small, flattened, ovoid nutlets. (Fig. 245.) Means of control Prevent reproduction by close cutting while young. If nearing maturity when cut the weed should be removed from the ground, as the large, swollen stems contain enough nutriment to ripen the 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.
