Herbaceous, puberulent or pubescent, ill-scented; stem usually branched, erect, ii0-3° high, its hairs mostly reflexed. Leaves slender-petioled, ovate, or the lower nearly orbicular, acute or obtuse at the apex, coarsely dentate, thin, narrowed, truncate or subcor- date at the base, 1-2' long; clusters numerous, several- flowered, dense; bractlets subulate, somewhat shorter than the calyx; calyx about 4" long, its teeth lanceo- late, sharp, bristle-pointed, spreading in fruit; corolla 6"-g" long, reddish-purple to whitish, its upper lip pubescent on both sides; nutlets shining. In waste places, eastern Massachusetts to Pennsylva- nia. Naturalized from Europe. June-Sept. Black arch- angel. Hairhound. Henbit. 21. STACHYS [Tourn.] L. Sp. PI. 580. 1753.

Calyx mostly campanulate, 5-10-nerved, S-toothed, the teeth nearly equal in our species. Corolla purple in our species, its tube narrow, not exceeding the calyx, the limb strongly 2-lipped; upper lip erect, concave, entire or emarginate; lower lip spreading, 3-cleft, the middle lobe broader than the lateral ones, sometimes 2-lobed. Stamens 4, didynamous, ascending under the upper lip of the corolla, the anterior pair the longer, sometimes deflexed or twisted after anthesis; anthers contiguous in pairs, 2-celled, the sacs mostly divergent.
