'with white veins and brown spines, whilst C. diacanlha has shining 

 .-green leaves with silvery lines and ivory-white spines. They 

 grow i8in. high. 



Echeverias. — These are used for edgings, divisional lines, &c, 

 and are readily increased by offsets. The flower-stems vary 

 from 6in. to i2in. in height. E. agavoides has glaucous 

 green fleshy leaves, each ending in a rigid spiny point; it is 

 used as a dot plant. E. metallica has large leaves, with a purplish 

 metallic lustre. E. Peacockii has light glaucous green leaves, with 

 a reddish tinge round the margins; it is also used largely as 

 a dot plant. E. secunda glauca is the one most commonly 

 grown ; it forms a rosette of glaucous fleshy leaves. 



Herniaria glabra is a creeping plant of neat, close habit, 

 suitable for filling in the groundwork; it has deep olive-green 

 foliage, and may easily be increased by division. It does not 

 grow more than 2in. from the ground. 



Kleinia repens is a succulent plant, growing 2in. high, and 

 is used for divisional lines. Its foliage is of a bluish hue. 

 Increased by division in spring. 



Mentha Pulegium gibraltarica is a useful groundwork 

 plant, very effective when surrounded with brighter colours; it 

 is a dwarf, dense-growing subject, having deep green foliage. 

 Height, 3in. to 5m. 



Mesembryanthemum cordifolium variegatum has creamy- 

 yellow leaves, and is used for filling in panels, &c. ; it grows 

 freely, and soon covers the ground. Increased by cuttings. 

 Height, 2in. 



Pachvphytum bracteosum is an attractive succulent plant, 

 the foliage forming a rosette of a light glaucous hue. Propagated 

 by leaves, pulled off from the old plants, and inserted in pots 

 or pans of light sandy soil, and placed in a dry, warm pit. It 

 grows ift. high, and forms a useful dot plant; or it may be used 

 for dividing lines. 



Sagina pilifera aurea, or glabra aurea, is an excellent 

 subject for filling in panels, forming, as it does, a dense yellow 

 carpet, not more than 2m. high. It may readily be increased by 

 pulling the tufts in pieces and transplanting. 



Santolina incana is a neat, dwarf-growing plant, 9m. high, 

 producing slender, twig-like growths, and fine silvery leaves. It is 

 useful as a dot plant, and may be propagated by cuttings, 

 taken in either spring or autumn. 



Saxifraga. — Several of these dwarf-growing subjects form 

 excellent carpeting plants, for either summer- or spring-bedding. 

 The foliage grows close to the ground, the flower-spikes rising 

 from 6in. to i2in. high. They are multiplied by offsets or
