ERYSIMUM. (HEDGE MUSTARD.) 

 A genus comprising a great number of plants 

 (prd. Ouciferse), of which only a small number are 

 of any garden value. These are of annual, bien- 

 nial, or perennial habit, and are easily raised from 

 seeds, or are propagated by cuttings struck under 

 glass. The seeds can be sown in a frame or green- 

 house, or in the open ground in spring. Common 

 soil. 



Principal Species : 



alpinum, 6", My., yel. ; a perofskianum, 1.}', My. to 

 var. of heiracifohum. Aug., aim., or. 



ERYTHRJEA. (CENTAUBY.) 



Pretty little annual, biennial, or perennial plants 

 (orA. Gentianeie) for the rockery in light soil. The 

 perennial, diffusa, likes a half-shady position in 

 peaty soil, and plenty of water during summer. 

 All are propagated by seeds sown in spring.

A genus of stately Californian Palms (ord.

 in an intermediate house and treated like Arecas. 



Principal Species :

ERYTHRINA. (CORAL TREE.) 

 Description. Showy shrubs, trees, or herbaceous 

 plants (tml. Leguminosrc), with fine racemes of 

 brilliant flowers. They are suitable for growing in 

 the stove or conservatory, and the herbaceous- 

 stemmed species are very effective if planted out of 

 doors in summer. 



Propagation. Young shoots removed in spring 

 with a heel attached, placed in sandy soil in gentle 

 bottom heat, and covered with a glass, will strike 

 readily. 



Soil. A rich compost of peat, loam, cow manure 

 and a little sand.
