perennial; stems 2–3 ft. high, probably woody at the base, branching at the upper part, obtusely 4-angled above, terete and striate below, very thinly to rather densely pubescent with spreading hairs; leaves of the main stems (including the 1/2–2 lin.-long petioles) 1/2–1 1/3 in. long, 1/4– 3/4 in. broad, those on the branches smaller, ovate or lanceolate, rarely elliptic, acute or obtuse, rounded at the base, serrate, denticulate or rarely some entire, glabrous or with thin minute adpressed pubescence or with longer scattered hairs above, greyish beneath, sometimes with exceedingly minute pubescence, sometimes thinly pilose on the conspicuously prominent veins; panicle with 1–2 pair of simple branches and a terminal one, 3 1/2–6 in. long, each with 4–9 whorls 1/2–1 1/2 in. apart, 6-flowered; upper 2–4 pairs of bracts flowerless, persistent, 1/4–1 in. long, 1–3 lin. broad, lanceolate or linear-lanceolate, acute, cuneately tapering into a short petiole, thin, glabrous above, minutely puberulous beneath, ciliate, coloured (pink?); flowering bracts very deciduous, leaf-like, thin?, lanceolate, acute, perhaps more or less coloured; pedicels 1–2 lin. long, pubescent; calyx-tube 3–4 lin. long, tubular-campanulate, pubescent outside, minutely puberulous within; upper tooth 1 1/2–2 lin. long, orbicular, obtuse; lateral and lower teeth bristle-like, the lower 1–1 1/2 (in fruit up to 2 3/4) lin. long; corolla moderately large, with widely gaping lips, minutely puberulous at the tips of the lips outside and more minutely within the tube, otherwise glabrous, pink (Thorncroft), lilac (Bolus); tube much exserted, 1/2– 2/3 in. long, very slightly curved, slender at the basal 2/3, dilated and compressed at the truncate mouth which forms the 3–5 lin.-long upper lip, which is abruptly constricted at the top of the very small auricle-like lateral lobes into a small subquadrate obtuse middle lobe; lower lip 3–5 lin. long, boat-shaped, obtuse; stamens much exserted, very unequal, upcurved at the tips; upper pair inserted at the middle of the corolla-tube, 7 lin. long, with free flattened filaments, minutely ciliate on the lower part; lower pair 5–8 lin. long, extending about 3 lin. beyond the upper, with the filaments united nearly or quite to the apex, glabrous; stigma not thickened, minutely bifid. null
