A/m erect, four-sided, the angles winged, from four to
six feet high, branched: branches slenderest where they join
to the stem, four-sided, the angles sharp and winged, stii-
ated between the angles, of a bright green, when young
thickly clothed with short rigid bristle-like hairs, which occasions
a rough hard feel, those soon wear off, and the stein
becomes smooth and somewhat glossy; rather slenderer at
the joints from where the leaves proceed. Leaves opposite,
sessile, 3-nerved from the base, much veined and rugged lanceolate,
unequally serrate, acute, very rough to the touch, the
roughness occasioned by the short rigid bristle-like hairs, with
which they are covered on both sides, entire from above the
middle ; the teeth sharp, rather distant. Spikes rather short,
crowded, in terminal panicles: the flower-stems purplish,
4-angular, very rough, being strigosely hispid. Flowers
crowded, numerous, purple, closely imbricate on the »pikes.
Bractes lanceolate, acute, strigose, about the length ot the
tube of the calyx. Calyx tubular, 5-toothed, strigosely hairy:
tube 5-angular, membranaceous between the angles; the
4 upper teeth nearly equal in length, acute, hispid, the
lower one about half the length. Corolla tubular ; die tube
cylindrical; the limb 5-cleft, segments unequal, ligulate,
slightly retuse, upper ones largest. Stamens 4, didynamous,
two rather longer than the others, inserted m the tube a
little below the mouth, and included: Jilaments very short.
Ovarium smooth and glossy. Style smooth. Stigma capitate.
