 fls. pink. 



Var. myriacdntha, W. D. Koch {M. myriacantha, DC. ). 

 Branches very prickly: Ivs. doubly glandular-serrate,

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

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

 known. H. HihSrnica, Smith, a low shrub with glaucous

 H. canina. H. rubella, Smith, vfiih d&rk green foliage, 

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

 hybrid with H. penduUna. H. reversa, Waldst. & Kit., 

 is similar and probably of the same parentage.
