 smaller and greyer, and though H, algarvensis has 

 an upright way of growth, and against a wall will

 low bushes, some quite trailing. H. formosum (as 

 often known as Cistus formosiis) is a capital plant in

 from a distance. ff. halimifolium has an almost 

 prostrate habit ; foliage also grey, and bloom abundant. 

 These are the only ones with yelloAv flowers, except 

 our small native Rock-rose, that I know well. H. 

 Tosmarinifolium is a beautiful dwarf bush, suited for 

 a sunny place in the front of the choicest shrub-bank. 

 Its leaves are small and narrow, Rosemary-shaped, 

 and dark in colour ; its many small flowers are milk- 

 white, of delicate texture, and extremely fugacious. 

 Then there are the many species and garden varieties 

 of the branches of the family that our common wild
