Wide-prickly Rose (Rosa platyacantha Schrenk). This species grows in foothills, mountain slopes, in gorges. It is a xero-mesophytic shrub, 1 to 2 m high with reddish bark. Prominent thorns are straight, pointed to the apex, abruptly widened at the base and very stiff. Compound leaves have five to nine orbicular leaflets with four to eleven large, pointed or obtuse teeth and sparse pubescence on the lower side. Yellow flowers are borne singly on 1.5 to 4 cm long, glabrous pedicels; sepals are lanceolate and tomentose on the upper sides. Black-violet globular fruits are 1 to 2 cm in diameter and crowned by nonconvergent sepals. Vitamin C and tannin levels are very high in the fruits.

Shrub, low or medium- sized, with reddish bark, branches diverging at an acute angle, branches and turions usually covered with uniformly long, firm, erect, flattened or abruptly markedly broadened whitish prickles, sometimes turning slightly upward; leaves with 5—9 leaflets; rachis unarmed, glabrous or with gossamer hairs; stipules narrow, generally glabrous, with divergent auricles; margins glandular; leaflets small, 6— 20 mm long, orbicular or broadly elliptic, with orbicular base; apex rounded or slightly acuminate, glabrous or sparingly pubescent along midrib, with 4—9 simple, large, obtuse or acuminate, distinctly asymmetrical teeth on each side, dark green above, pale green beneath. Flowers solitary; pedicels 1.5— 4 cm long, usually smooth; hypanthia globose or slightly longer than broad, smooth; sepals simple, lanceolate, 1—2 cm long, shorter than petals, with slightly broadened mucro, margin and upper surface tomentose-lanate; lower surface smooth; corolla 3—5 cm in diameter; petals large, yellow; stigma head large, white-tomentose; fruit globose, 1—2 cm in diameter, like apically thickened pedicels, black-violet when ripe, crowned in fruit by divergent or upwardly-directed, not convergent sepals.

Economic importance. Sometimes, as in the city of Alma-Ata, cultivated as an ornamental plant.
Note. R. heteracantha Kar. et Kir., here considered as a synonym of this species, is distinguished by a mixture of numerous thin acicular prickles passing into normal, firm, markedly flattened prickles. It appears to be a problematic form, perhaps a hybrid of R. platyacantha Schrenk. X R. spinosissima L.
