with plants ; consequently the evaporation 

 ol moisture from the soil is checked by the 

 leaves and branches. For their culture in 

 the garden, from 18 in. to 2 ft. of such soil, 

 resting on a dry bottom, would be desirable. 

 Beds or groups of hardy heaths would make 

 a charming display. Such groups would 

 harmonise well with the different fir-trees 

 in or near to the pinetum. Nothing could 

 exceed their beauty, congruity, and adapta- 

 bility, as furnishings for rockwork. Peat- 

 earth could easily be introduced among the 

 crevices, between stones, &c., and the 

 heaths introduced there. They would 

 thrive admirably in such situations, and 

 contrast well with the ferns and other 

 plants that find a congenial home in such 

 localities. 



Erioste'mon (not. ord. Euta'cese). 



An interesting genus of greenhouse ever- 

 green shrubs, extremely elegant in growth, 

 and producing in profusion beautiful star- 

 shaped blossoms, white pale pink or rose 

 in colour : they thrive best in fibrous peat 

 mixed with silver sand and a little rich 

 loam. They are propagated by cuttings 

 put in sandy peat under a hand-glass about 

 April, and subjected to gentle bottom heat. 

 The plants require good drainage, and 

 should be watered with care. 



Ero'dium (not. oni. Gerania'cese). 



The plants of this genus are partly hardy 



warm situations, and forming charming 

 little plants for rockwork, edgings, and 

 flower-borders. They are propagated by 

 seed or division of the roots, and succeed in 

 any soil. Perhaps the best known of the few 

 pecies that have been introduced into this 

 country is Erodium peiargonicEflonuu, with 

 white flowers spotted with purple. It is a 

 hardy perennial. 



Erys'imum (not. ord, Crucif erae). 



Eree-flowering, and exceedingly showy 

 plants, producing in beds, mixed borders,

and ribbons, a very fine effect. They are 

 chiefly biennials and perennials, and are 

 raised from seed, which may be obtained 

 from any seedsman. They do best in light rich 

 soil. One of the best known is Erysimum 

 Peroffskianuni, with showy but small orange 

 flowers. It is a hardy annual about 18 

 inches in height. 



Erythri'na (nat. oni, Legumino'sse). 



A splendid genus of half-hardy shrubs, 

 with fine leaves and brilliant scarlet flowers. 

 Planted in a warm, favourable situation out 

 of doors they grow freely, but in most 

 localities they succeed best in a greenhouse, 

 with the advantages of a warm house early 

 in the season. They succeed best in rich
