TO THE FLOWER GARDEN. 239 



racemes of white sweet-scented flowers, furnishes us with a 

 hard and durable timber. For the flower garden and shrub- 

 bery, however, the species most appropriate is the Rose 

 Acacia [R. hispida), for which the allied species, J^. macro- 

 phylla, may be substituted in situations where there is space 

 for its somewhat larger growth: both bear long drooping 

 racemes of large rose-coloured flowers. The Rose Acacias gi'ow 

 well in moderately good garden soil ; but they require rather a 

 sheltered situation, or their brittle branches are liable to be 

 broken by the wind. They should be grown as standards, 

 with a straight stem of three feet or more in height. They 

 are usually grafted on the common False Acacia, and the 

 precaution is generally taken to graft close to the root and a 

 little below the ground, not only to avoid fracture, to which 

 the united parts are liable, but also to facilitate union, which 

 is promoted by drawing up the earth so as to cover all but 

 the top buds of the graft. R. inermis is pretty as a standard. 



ROCHEA. [Crassulaceae.] Greenhouse evergreen suc- 

 culents. Sandv loam. Cuttings. R. falcata, flowers scarlet. 



ROCK BRAKE. See Allosorus. 



ROCKET. See Hesperis. 



ROCK ROSE. See Cisxus. 



ROELLA. [Campanulacege.] Greenhouse evergreen 

 dwarf shrubs. Sandy peat, with a little light loam. Cut- 

 tings in sand under a bell-glass. R. ciliata, flowers greyish, 

 with purple centre. 



RONDELETIA. [Cinchonaceee.] Stove evergreen shrubs, 

 well worth cultivating, especially R. speciosa major. The 

 plant may be rendered very bushy by culture, and then the 

 best plan is to grow it on, because the flowers come at the 

 ends of all the shoots. Cuttings should be taken when the 

 plant is in flower, selecting the tops of those shoots that have 

 no bloom. They strike very readily in sand, and should not 

 be more than two inches long, one inch of which should be 

 inserted in the sand, and the other above. After watering 

 them in cover with a bell-glass, and place them in slight 

 bottom heat ; wipe the glasses daily, and attend well to 

 moisture. When they have struck pot them off" singly in 

 three-inch pots, in a compost of equal parts peat and loam, 

 with a little sand. They may at once be placed in the stove.
