Botanical Description

Shrub 1-1.2 m in height. Perennial shoots are brown, one-year-old - reddish-brown with a bluish bloom. The spikes are straight or slightly curved up to 1 cm long, conical, slightly flattened at the base, light gray, shorter than large leaves. At the base of one-year-old shoots mixed with small needle-shaped straight or slightly curved spines [2] .

Leaves are pinnate, with three, less often with two pairs of leaflets and one apical leaflet, equal in size to the upper lateral leaflet. Leaflets broadly obovate 0.8–1.9 (2.2) cm long, 0.6–1.3 (1.7) cm wide, scattered hairy from below, glabrous above, sparse-toothed, serrated, serrated twice serrated and serrated with sessile, light glands on the lower and small teeth, on the upper without glands. The leaf axis is covered with sparse long hairs and scattered short-seated glands. Stipules narrow, bare from above, covered with long hairs along the vein below, glandular along the edge [2] .

The flowers are single, less often two. Terry towel red-pink, up to 7.5 cm in diameter. Pedicels naked, up to 2 cm long. Hypanthia elongated, ovate, glabrous. Sepals are whole, 1.7-1.9 cm long, rarely stalky-glandular on the outside with sparse long hairs, densely shortly pubescent on the inside, directional, non-falling by flowering upwards. Ripe fruits are orange-red. The bract is single, elongated-oval, serrate-dentate, with glands along the margin, bare above, covered with rare long hairs with single glands or without them, at the base with two narrow stipules, similar to leaf stipules [2] .

Flowering in the second half of May - the first half of June. Fruiting in late August - September.

Distribution and Ecology

Endemic of the Pamir-Alai . In nature , the range of the species covers the Western Pamir and, possibly, enters the territory of Afghanistan [2] .

The habitat was apparently preserved thanks to humans: it is found in gardens and near settlements at an altitude of 1600–2300 m above sea level.
