aciculata ; stipulis adnatis, latis, margine haud glandulosis, apicibus liberis, ovatis ; 
floribus solitariis ; pedunculis nudis; calycis tubogloboso, nudo ; lobis basi ovatis, 
apicibus elongatis ; petalis magnitudine mediocribus, rubellis; stylis liberis, villosis ;

Ascherson & Graebner, Syn. Mitteleur . FI. vol. vi. p. 307 (1902). 
Stems much armed ; prickles slender, subulate, passing gradually into copious 
aciculi, some in infrastipular pairs. Leaflets 5-7, oblong, middle-sized (i-if in. 
long), green, less rugose than in Rosa rugosa , glabrous on the upper surface, thinly 
pubescent, not at all glandular beneath ; petioles pubescent and aciculate ; stipules 
adnate, broad, not gland-margined, with ovate free tips. Flowers solitary ; peduncles 
naked. Calyx-tube globose, naked ; lobes ovate at the base, with a long point, 
i-i in. long. Petals middle-sized, pink. Styles free, villous. Fruit globose, naked, 
bright red, J-J in. diameter, crowned with the erect persistent sepals. 
The drawing represents one of the many Rosa rugosa Thunb. 
hybrids. In all Rose hybrids and crosses there is generally one 
character which persists until at least the third or fourth generation. 
Thus the Rosa multijlora Thunb. crosses have ciliated stipules, and 
in the Rosa rtigosa hybrids the character of the reticulated, deeply 
veined, rough, dark green leaves is found with but little modification 
in all the hybrids now known. Rosa warleyensis was raised from 
seeds which were sent to Warley many years since and which were 
said to have been gathered from a wild Rose. It shows unmistakable 
signs of Rosa blanda Ait. influence, and is in fact about midway 
between its two parents. It is a pretty and free-flowering Rose, quite 
distinct from the generality of Rosa rugosa hybrids, and it well 
deserves a place in the garden.
