Stem tall, green, arching ; prickles scattered, stout, falcate, uniform. Leaflets 
5-7 > ova l or elliptical, acute, middle-sized, simply serrated, green and glabrous or 
pubescent above, slightly pubescent, rarely glabrous beneath ; petioles hardly at all 
glandular and slightly pubescent ; stipules adnate, gland-ciliated, with ovate-lanceo- 
late free tips. Flowers 3-6, in a corymb ; pedn ~ es glandular; bracts ovate-lanceo- 
late. Calyx-tube ovoid or ellipsoid, nakc obes copiously pinnatifid, f in. long, 
not leaf-pointed, slightly glandular on the back. Petats pink or white, 1 in. long. 
Styles glabrous, loosely coherent, more or less protruded beyond the very conical 
disc. Fruit urceolate-globose, red, naked, ripening late ; sepals deciduous. 
Rosa stylosa Desv. in one or other of its forms is a frequent plant 
in the southern counties of England and extends eastward to Styria 
and Hungary. The typical species is characterized by its very broad- 
based prickles with hooked point, leaflets hairy on both sides, simply 
serrate, long, somewhat glandular, hispid peduncles, glabrous styles 
more or less decidedly exserted from a very conical disc, and white 
flowers ; but much the commoner form both in Britain and on the 
continent is Rosa systyla Bast., regarded by some as a mere variety,
