Impatiens thomsonii subsp. thomsonii
Annual 8-55 cm tall, glabrous. Leaves 20-70 x 10-26 mm, elliptic-lanceolate or elliptic-ovate acuminate, serrulate to crenate-dentate, lateral veins 7-9 pairs. Peduncles slender, 15-90 mm long. Bracts linear to lanceolate, 1.5-5 mm long, yellowish-brown, usually uncinate. Flowers 8-15 mm long, pink, white and yellow, spotted brown within; pedicel up to 18 mm long. Lateral sepals subcordate, c. 3 mm long; lower sepal conical, c. 6 mm long, gradually tapering into a curved yellow, 2-5 mm long, spur. Anterior petal entire; lateral united petals similar to those of Impatiens glandulifera but smaller (12.5-13 mm). Capsule narrow, clavate, 14-19 mm long, nodding. Seeds ruminate to minutely verrucose, ± oblong, 2-3 mm long.
Fl.Per.: Late July-August.
Type: Piti & Kunawar, 9-10,000', Thomson 68 (K).
Distribution: Temperate Himalayas from Hazara and Kashmir to Kumoan and eastward to Sikkim.
Found in the dry inner Himalayan ranges from 1700-4000 m. Fairly common. Variable in the size of the plant parts; an intermediate species between Impatiens glandulifera & Impatiens suleata but with smaller flowers having a yellow spur and brown blotches within. The bracts are also narrower. The var. ecalcarata Hook. f. has been reportedly collected from Dras by Gammie; it differs from the type variety in the absence of a spur or a very short one. A specimen from Kurram (above Makai, c. 2500 m, M.A. Siddiqi & Y. Nasir 6511 (RAW) may well belong here.
