Part II. SEMPER VIVUM. 335 



across when fully expanded. It is, when grown at all in this 

 country, usually kept in the greenhouse, but is hardy in warm 

 well-drained spots on rockwork. It Ought to be placed in some 

 dry spot under a ledge of rock, and might be tried with 

 advantage on the top of an old wall or on a ruin. A native of 

 the Canary Islands ; like the other Houseleeks, easily increased 

 by division or cuttings. 



SEMPERVIVUM MONTi^'aM..— Mountain Houseleek. 



A DARK-GREEN kind, smaller than the common Houseleek, 

 with a very pleasing, almost geometrical, arrangement of leaves, 

 which are pubescent and glandular on both sides, ciliated, 

 forming neat rosettes, from which spring dull rosy flowers in 

 summer. It is very suitable for forming edgings or for rock- 

 work ; like all the others, grows in any soil, and, like all its 

 fellows, is very easily propagated. A native of the Alps. When 

 masses of it are in flower, they are visited by great numbers of 

 bees. 



SEMPERVIVTJM S0B01LWE-RXm..—Ifen-and-C/iicken S. 



One of the neatest and most distinct in appearance of the 

 family, particularly distinguished by growing in firm dense 

 tufts, and throwing off little round offsets so abundantly that 

 these are pushed clear above the tufts, and lie rootless, small, 

 brownish-green balls on the surface. The full-grown rosettes 

 are of a peculiarly light green, and of a decided chocolate brown 

 at the tips of the under side of the leaves, for nearly one-third 

 of their length. The small leaves of the young rosettes all 

 turning inward, they appear of a purplish-brown colour. The 

 rosettes are usually not more than one inch and a half in 

 diameter, but I have seen them in France more than three 

 inches ; however, whether they were the rosettes of a form 

 larger naturally than the common one, or the result of a higher 

 culture, I cannot say. The plant, which I have not seen in 

 flower, is admirably suited for forming wide tufts on rockwork, 

 on banks beneath the eye. It grows freely in any soil. 



SEMPERVIVTJM TECTOEXJM. — Common Houseleek. 



A NATIVE of rocky places, in the great mountain ranges 

 of Europe and Asia, but which, having been cultivated from
