THE BOOK OF ROSES. 93 



Tube of the calyx, round, covered, as well as the divi- 

 sions, with straight close thorns, resembling those 

 of a horse-chesnut. 



Sepals, dilated, pointed, cottonous on the margin, 



formed like those of the Rosa bracteata. 

 This little shrub, a native of China, bears the cold 



of our winters without injury. Lindley places it in 



the tribe o&Rosa canina ; but on the whole, it bears a 



closer affinity to the Macartney rose. 



Rosa Microphylla Striata. 



Differs very little from the preceding. The leaf is 

 composed of seven leaflets ; oval, finely and regularly 

 toothed, of a pale green colour. The thorns are reddish 

 in the young shoots. 



V. Rosa Clynophylla, or Drooping-leafed Rose. 



Skrub, bushy. 



Stems, bristly. 



Branches, slight, hairy. 



Thorns, stipular, geminated. 



Leaves, drooping. 



Leaflets, oblong, elliptic, doubly-toothed, glossy on the 



upper surface, downy on the under. 

 Leafstalks, glandulous, hairy, sometimes thorny. 

 Stipules, narrow, fringed, pointed. 

 Flowers, solitary. 

 Flower stalks, very short, hairy. 



Tube of the calyx, round, hairy, sometimes accom- 

 panied with floral leaves. 

 Sepals, entire, pointed, bristly. 



Petals, white, rather heart-shaped ; yellow at the base. 

 Fruit, round. 



This is a variety which has been much celebrated, 

 but scarcely exists except in the beautiful drawing of 

 Redoute.
