5. M. punctàta, L. (Horse-Mint.) Perennial, minutely downy (2–3° high); leaves petioled, lanceolate, narrowed at base; bracts lanceolate, blunt, obtuse at base, sessile, yellowish and purple; teeth of the downy calyx short and awnless, rigid, soon spreading; corolla nearly smooth, yellowish, the upper lip spotted with purple, notched at the apex, the tube scarcely exceeding the calyx.—Sandy ground, N. Y. to Minn., south to Fla. and Tex.
6. M. citriodòra, Cerv. Annual, 1–3° high; bracts narrowly oblong, their slender awned tips spreading or recurving; calyx-teeth slender, at length usually spreading; corolla white or pinkish, not spotted.—Neb. to Tex.
20. BLEPHÍLIA, Raf.
Calyx ovoid-tubular, 13-nerved, 2-lipped, naked in the throat; upper lip with 3 awned teeth, the lower with 2 nearly awnless teeth. Corolla inflated in the throat, strongly and nearly equally 2-lipped; upper lip erect, entire, the lower spreading, 3-cleft, its lateral lobes ovate and rounded, larger than the oblong and notched middle one. Stamens 2, ascending, exserted (the upper pair minute or none); anthers, etc., as in Monarda.—Perennial herbs, with nearly the foliage, etc., of Monarda; the small pale bluish purple flowers crowded in axillary and terminal globose whorls; in summer. (Name from βλεφαρίς, the eyelash, in reference to the hairy-fringed bracts and calyx-teeth.)
1. B. ciliàta, Raf. Somewhat downy (1–2° high); leaves almost sessile, oblong-ovate, narrowed at base, whitish-downy underneath; outer bracts ovate, acute, colored, ciliate, as long as the calyx; corolla hairy.—Dry open places, Mass. to Minn., south to Ga. and Kan.
2. B. hirsùta, Benth. Taller, hairy throughout; leaves long-petioled, ovate, pointed, rounded or heart-shaped at base; the lower floral ones similar, the uppermost and the bracts linear-awl-shaped, shorter than the long-haired calyx; corolla smoothish, pale, with darker purple spots.—Moist shady places, Vt. to Minn., south to Ga. and E. Tex.
21. LOPHÁNTHUS, Benth. Giant Hyssop.
Calyx tubular-bell-shaped, 15-nerved, oblique, 5-toothed, the upper teeth rather longer than the others. Corolla 2-lipped; upper lip nearly erect, 2-lobed, the lower somewhat spreading, 3-cleft, with the middle lobe crenate. Stamens 4, exserted; the upper pair declined, the lower and shorter pair ascending, so that the pairs cross; anther-cells nearly parallel.—Perennial tall herbs, with petioled serrate leaves, and small flowers crowded in interrupted terminal spikes; in summer. (Name from λόφος, a crest, and ἄνθος, a flower.)
1. L. nepetoìdes, Benth. Stem stout, 2½–6° high, sharply 4-angled, smooth, or nearly so; leaves ovate, somewhat pointed, coarsely crenate-toothed (2–4´ long); spikes 2–6´ long, crowded with the ovate pointed bracts; calyx-teeth ovate, rather obtuse, little shorter than the pale greenish-yellow corolla.—Borders of woods, Vt. to Minn., south to N. C. and Tex.
2. L. scrophulariæfòlius, Benth. Stem (obtusely 4-angled) and lower surface of the ovate or somewhat heart-shaped acute leaves more or less pubescent; calyx-teeth lanceolate, acute, shorter than the purplish corolla (spikes 4–15´ long); otherwise like the last.—Same range.
