Stem tall, arched, reaching a height of 6-8 feet; flowering branches usually 
densely prickly. Prickles very slender, straight, needle-like, passing gradually into 
aciculi, often in pairs at the base of the leaves. Leaflets moderately large, thin, 
oblong, acute, glaucous, simply openly toothed, glabrous on both surfaces or pubes- 
cent beneath ; petioles glabrous or pubescent, slightly glandular ; stipules adnate, 
with ovate-lanceolate gland-ciliated free tips. Flowers one or few ; peduncles long, 
naked or thinly setose ; bracts ovate. Calyx-tube ampullaeform ; lobes lanceolate, 
simple, an inch long, leafy at the tip, naked or glandular on the back. Petals bright 
pink. Styles free, villous, not protruded. Fruit bright red, pulpy, erect or more 
often cernuous, sometimes subovate and shortly constricted at the apex or elliptical 
and tapering at each end, sometimes suboblong or obovate-pyriform, much narrowed 
at the base, crowned by the persistent connivent sepals. 
Rosa acimlaris is a northern plant, extending through northern 
Russia and Siberia to Japan and across Behring Sea into northern
