Ascherson & Graebner, Syn. Mitteleur. FI. vol. vi. p. 308 (1902). 
Stem low, spreading ; prickles small, moderately stout, sometimes in infrasti- 
pular pairs, without any intermediate aciculi. Leaflets 7, oblong, obtuse, simply 
serrated, the larger an inch or more long, glabrous on the upper surface, pubescent 
beneath ; petioles pubescent, not glandular ; stipules adnate, with deltoid entire free 
tips. Flowers solitary; pedicels long, glabrous, slightly aciculate. Calyx-tube 
ovoid, slightly aciculate ; lobes lanceolate with a long point, simple, 1 in. long, 
pubescent and furnished with many aciculi on the back. Petals middle-sized, dull 
purplish red. Styles free, not protruded beyond the disc. 
This hybrid between Rosa kumilis Marsh, and Rosa rugosa 
Thunb. was raised not long ago in America. The characters of the 
kumilis parent greatly predominate in it over those of the rugosa 
parent. Although the colour is not particularly pleasing, it is never- 
theless a useful Rose, and is especially well adapted for the wild 
garden and for hedges and plantations. It is exceedingly floriferous, 
hardy and quick growing, and forms a thick, compact bush, while its 
abundant and bright-coloured fruits make it very ornamental in the 
autumn.
