 surface hoary ; upper surface green, pilose. Stem shrubby, pro- 

 cumbent. Branches elongated. Europe (Britain), North Africa, 

 and West Asia. (Sy. En. B. 168.) A curious variety, or (ac- 

 cording to Bentham) an accidental deformity, occasionally seen 

 in gardens, and supposed to have been originally found near 

 Croydon, with small, narrow, deeply cut petals, has been 

 figured under the name of H. surrejanum. The Bock-roses of 

 our gardens are chiefly varieties of this species, which, under 

 cultivation, varies much in the colour of its flowers. The follow- 

 ing are amongst the most distinct of the innumerable forms : 



H. v. barbatnm (bearded). I. ovate or elliptic-lanceolate, clothed 

 with long white hairs. (S. C. 73.) 



H. v. hyssopifolium (Hyssop-leaved), fl. coppery-red (S. C 58) 

 or saffron-coloured (S. C. 92). I. flat, linear-lanceolate or lanceo- 

 late ; upper surface glossy. Of the one with coppery-red flowers, 

 there is a double form. 



H. v. macranthum (large-flowered), fl. whitish, yellow at the 

 base ; racemes terminal, secund, simple. Summer. 1. flat, ovate- 

 oblong, acutish, densely tomentose beneath, smooth above. 

 Branches shrubby, procumbent, rather tomentose. 



H. v. mutabile (changeable), fl. pale rose-colour, yellow at base, 

 becoming almost white before petals fall. Summer. (S. C. 106.) 



H. v. ovalifolium (oval-leaved), fl. yellow. I., lower ones round- 

 ish or oval, glossy green above, white beneath ; margins more or 

 less revolute. SYN. H. serpylltfolium. (S. C. 60.)
