Lobelia unidentata

stems diffuse, angular, scabrous, branched; leaves subsessile, alternate, opposite or ternate, with cartilaginous margins, scabrous; lower ones ovate or roundish, 1–2-toothed on each side; the upper lanceolate or linear-lanceolate, bidentate or entire; pedicels subterminal, much longer than the leaf; calyx-tube scabrous or hairy; lobes linear, reflexed, longer than the tube, 2–3 times shorter than the corolla. Perennial, very variable in habit and size, 3–4 inches or 2 feet long. Lower leaves 2–4 lines long and 2–3 lines wide; the middle 4–6 lines long, 1 1/2–2 l. wide; the uppermost sublinear, acute or mucronulate, the margins revolute. Peduncles at the base with 2 linear bracteæ, minutely downy as the calyx and corolla. Capsule as in D. scabra, from which it is distinguished by the more distant, broader, and toothed leaves, and prostrate stem with elongate branches. It varies also with smooth stems.
