Stem green, spreading ; prickles irregular, scattered, strongly hooked. Leaflets 
5 or 7, small, oblong, obtuse, doubly toothed, glabrous on the upper surface, slightly 
pubescent beneath ; petioles glandular ; stipules narrow, gland-margined, adnate, 
with small free tips. Flowers 1 or 2 ; peduncles aciculate and glandular. Calyx- 
tube turbinate ; lobes ovate-acuminate, simple or slightly compound, naked on the 
back. Petals middle-sized, white or pink. Styles villous, much protruded, cohering

This Rose was first distinguished by Sprengel, and was described 
by him from specimens collected at the foot of Mount Baldo in northern 
Italy. Its flowers are pale pink or white tinted with rose, but rarely 
red, solitary or in pairs, occasionally as many as five on a stem. It is 
a beautiful and very free-flowering Rose. 
Wild hybrids between Rosa gallica L. and Rosa arvensis Huds. 
are common in France and Switzerland, and they have given rise to
