R. beggeriana (su/arāy; Javānšir, p. 155), “a highly polymorphic species,” which has induced “some authors to split it up [into varieties], usually on the basis of a single character” (Zieliński, p. 14; cf. the 14 varieties thereof recorded by Ṯābeti for Persia, pp. 631-34). It is a shrub, 2-2.5 m high, with small white flowers in corymb or panicles; habitat: Gorgān, Māzandarān, Semnān, Tehran, Isfahan, Kohgiluya and Boir Aḥmad, Yazd, and Kermān (Ḵātamsāz, pp. 45, 47); also reported from Afghanistan, Turkmenistan, etc. (Zieliński, pp. 13-14).

Rosa Beggeriana, var. genuina, is a wild Rose of central Asia which has the merit of keeping in bloom here all summer long. Its introduction into cultivation is due to Dr. Aitchison, botanist of the late Afghan Boundary Survey who found it "a common shrub at the western extremity of the Kuram district and throughout the Hariáb, in vicinity of streams and water courses; it is also very common near cultivation, where it forms natural hedges along the various channels of irrigation, at an altitude of from 4,000 to 9,000 feet. It forms a bush of from four to six feet in height, the latter in more favored localities. When in bloom it is covered with a mass of pure white small flowers. The fruit is little larger than an ordinary pea, at first orange-red, when fully ripe of a deep purple-black. The shrub is briar-scented. This species is employed, as well as R. Eglanteria and R. Ecea, the Gooseberry, and Hippophae, in forming hedges in the Hariáb district; and is much browsed by cattle, especially goats"*

This Afghan Rose forms here a stout, tall bush, five or six feet high, with slender and rather flexible branches, without prickles, and sparingly armed with slender, slightly recurved spines. The leaves, which are composed of three or four pairs of small, oval, sharply serrate leaflets, are pale gray-green. The hardiness of this plant and its habit of blooming continuously throughout the season, make it a useful, as well as an interesting, addition to single Roses.
