Stem short, erect ; branches slender, dark brown. Prickles crowded, passing 
gradually into aciculi, straight, slender. Leaflets 7-1 1, usually 9, oblong, obtuse, 
small, simply sharply serrated, green and glabrous on both surfaces ; petioles glabrous, 
aciculate ; stipules adnate, with short deltoid free tips, slightly gland-ciliated. 
Flowers solitary ; pedicels long, densely setose. Calyx-tube ampullaeform, glabrous ; 
lobes simple, ovate, leaf-pointed, not glandular on the back. Corolla bright dark 
red, in. in diam. Styles not exserted. Fruit ampullaeform, naked, bright red, 
pulpy, ripening at the end of August, crowned by the erect persistent sepals. 
This beautiful, dwarf, dark-flowered variety of Rosa acicularis 
Lindl. has only recently been introduced into England. The plant 
cultivated in the Royal Gardens, Kew, was received from the Botanic 
Garden at Copenhagen. It has also been received from the Botanic 
Garden at Wurzburg. It most resembles Rosa Malyi Kern, or Rosa 
rubella Smith in its dwarf habit and copious, dark red flowers. There 
is a specimen in the Kew herbarium, collected in 1864 by Tschonoski 
on the well-known mountain Fujiyama in the island of Nippon. The 
seeds were first distributed by the Botanic Garden of St. Petersburg 
about 1870.
