Spec. Char., S,-c. Stipules linear, divaricate, 

 dilated at the apex. Leaflets glaucous, flattish. 

 Tube hemispherical. (Don's Mill.) Stem 

 prickles unequal, scattered. A deciduous 

 shrub. Levant. Height 4 It. to 10 ft. Li- 

 troduced before 16-29. Flowers fine trans- 

 parent yellow, double ; July. 



This sort does not flovrer 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.
