should be seasonal ; that is, the foliage should be grown to as 

 perfect a state as possible, and then well ripened, and the bulbs 

 dried and rested for some weeks ; subsequently the plants 

 should be again watered and excited into growth, when the 

 bloom appears. They increase bj means of the offsets from 

 the bulbs. The principal ones grown are B. grandiflora, pink ; 

 B. minor, pink ; and B. multijiora, red. 



BRYANTHUS. [Ericaceae.] Pretty diminutive ever- 

 green under-shrubs, requiring shelter rather from heat and 

 dryness than from cold. Sandy peat soil. Increased by 

 cuttings in sand under bell-glasses, and kept quite cold. 



BRYOPHYLLUM. [Crassulacege.] A curious succulent 

 greenhouse plant, with an upright stem, opposite leaves, and 

 the flowers in a terminal spreading bunch. It requires to be 

 kept warm and dry in winter, like Crassulas and other 

 succulents, and is interesting from the fact that the leaves, 

 laid flat on a pot of soil, will produce a number of young 

 plants from the indentations on their margins, by which 

 means it is readily propagated. 



BUCKTHORN. See Rhamnus. 



BUDDLEA. [Scrophulariacese.] Evergreen shrubs. 

 There are many stove and greenhouse species, which, though 

 pretty, are of little importance in cultivation, B. Lindleyana, 

 a species requiring the protection of a wall or a cold green- 

 house, and B. globosa, a fine hardy shrub, are the most 

 desirable. They all grow freely in a light loamy soil, and 

 may be propagated by cuttings or layers. 



BUGAINVILL^A. [Nyctaginacese.] Stove shrubs. B. 

 spectabilis is a fine scrambling evergreen, growing very freely 

 in fibry, loamy soil, but seldom flowering until it has attained 

 some age and size. It is propagated readily by cuttings in 

 sand. The beauty of this plant resides in the large rosy- 

 purple bracts which surround the flowers. 



BULBINE. [Liliaceae.] Greenhouse perennial herbs, in 

 some cases bulbous. Soil, sandy loam, well drained. Pro- 

 pagated by offsets or division. 



BULBOCODIUM. [Melanthace«.] Beautiful dwarf 

 hardy crocus-like bulbous plants. Soil, sandy loam. In- 

 creased by offsets. The chief are B. vernum, purple ; and 

 B. versicolor, lilac and yellow.
