A little, compact, bright green plant. Branches 
naked, slender, somewhat flexuose; prickles under the 
stipules, straight? Stipules very narrow, spreading at 
the tip. Petioles somewhat prickly, very slender; 
leaflets 5-9, very small, shining, roundish ovate, point- 
ed, quite free from pubescence, finely serrated. 
Flowers solitary, with a narrow pointed bractea, very 
double, pale red; calyx covered all over with very close 
set, straight prickles; tube round; sepals very short, 
dilated, pointed, downy at the edge (like those of R. 
bracteata in shape). 
A charming little shrub resembling the Macartney 
Rose in general appearance; and particularly in the 
shape of the divisions of its calyx. It differs from all 
in this section in its very densely muricated calyx and 
narrow stipulz. See p. 9.
