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. inetallica 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. seamda glmica 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 5in. 



MesembryanthemuiM cordifolium variegatum has creamy- 

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

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 m.ultiplied by offsets or
