Spec. Char., §c. Stipules linear, divaricate, 
dilated at the apex. Leaflets glaucous, flattish. 
Tube hemispherical. (Dons Mill.) Stem 
prickles unequal, scattered. A deciduous 
shrub, Levant. Height 4 ft. to 10 ft. In- 
troduced before 1629. Flowers fine trans- 
parent yellow, double; July. 
This sort does not flower freely, except in 
open airy situations ; and, if trained against a 
wall, exposed to the north or east rather than 
to the south. Its flower buds are apt to burst 
on one side before they expand, and conse- 
quently to become deformed; to prevent this, 
the blossom buds should be thinned, and care 
taken that they have abundance of light and air. 
Watering it freely in the flowering season is found 
advantageous ; and the shoots, in general, ought 
not to be shortened. This beautiful species 
is said to flower freely, if grafted on the musk 
cluster at 8 or 10 feet from the ground ; or it will do well on the China rose.
