 fls. yellowish, rather large. B.M. 1570. Gn. 56:1249. 



Var. mitissima, W. D. Koch (var. intrmis, Thory. 

 It. mitlssima, Gmelin). Branches almost unarmed: 

 fls. pink. 



Var. myriacantha, W. D. Koch (R. myriacantha, DC.). 

 Branches very prickly: Ivs. doubly glandular-serrate, 

 very small: fls. small, white, blushed. Red. Ros.( 1:6,7). 

 There are also vars. with double or semi-double, pink, 

 white or yellow fls. (Gn. 29:544). Several hybrids are 

 known. R. Hibtrnica, Smith, a low shrub with glaucous 

 green foliage and small pale pink fls., is a hybrid with 

 R. canina. R. rubella, Smith, with dark green foliage, 

 red fls. and scarlet, pendulous ovate-oblong fruits, is a 

 hybrid with R. pendulina. R. revtrsa, Waldst. & Kit., 

 is similar and probably of the same parentage.

Var. Harisoni, Hort., Harrison's 

 Yellow Rose, is of paler color and a 

 little less double than Persian Yel- 

 low, but it blooms more freely, is 

 more vigorous, hardier and easier to 

 grow. It is of American origin and 

 may be a hybrid of Persian Yellow 

 with Rosa spinosissima.
