I.C. Hedge

Perennial with a woody rootstock. Stems erect slender (15-) 30-60 cm, with scattered leaves, hirtulous with rather stiff spreading eglandular hairs. Leaves linear, 25-40 x c. 3 mm, entire margined, with indumentum as on stem; petiole absent or almost so. Verticillasters 2-3, widely separated, 12-15 mm in diameter, c. 16-24-flowered. Bracts linear subulate ± adpressed to calyces, prominently ciliate on margins, shorter than calyces. Calyx turbinate, straight, glabrous, or apically with long eglandular hairs, 6 mm long and 3.5 mm wide at throat, regularly truncate, with very short hairs within the throat; teeth 10, c. 0.5 mm erect, mucronulate. Corolla white c. 10-12 mm; upper lip densely bearded; lower lip longer than upper. Nutlets 2.5 x 1.5 mm, oblong, trigonous, apically rounded truncate.

Type: "Hab. in Napalia, Kamaon" [Wallich Cat. no. 2044] E, K.

Distribution: Kashmir, Kumaon to Sikkim, Burma.

A very distinctive species on account of the long linear leaves, widely separated verticillasters and the short turbinate often glabrous calyces. I have seen no recent gatherings from our area.
