Stem erect, 3-4 feet long, bright brown. Prickles stout, slightly hooked, equal, 
scattered and often in pairs at the base of the leaves. Leafiets 5-7, oblong, acute, 
middle-sized, membranous, simply serrated, green and glabrous above, paler and 
slightly pubescent beneath ; petioles slightly pubescent ; stipules broad, with large, 
ovate, free tips. Flowers one or few ; peduncles short, rarely setose ; bracts large, 
ovate. Calyx-tube globose, naked ; lobes simple, leaf-pointed, i in. long, slightly 
glandular on the back. Petals rather large, pink. Styles villous, free, not protruded 
beyond the disc. Fruit large, globose, red, pulpy, naked, crowned by the erect 
persistent sepals. 
Rosa nutkana inhabits the north-west coast regions of North 
America from Alaska to northern California. It was first found by 
Menzies in Vancouver’s Island in 1790, and rather later by Haenke 
at Nutka Sound. It most resembles Rosa hlanda Ait. in habit, but 
differs in the presence of many robust prickles on the flowering 
branches, some of them in infrastipular pairs. It resembles also 
Rosa cinnamomea L. in its short peduncles and large bracts, but the 
fruit is much longer. It was sent from the Arnold Arboretum to the 
Royal Gardens, Kew, in 1884. Both Nuttall and Douglas recognised 
it as a distinct species, but did not describe it.
