BOUVAEDIA. 



This fine genus of Rubiacea contains many pretty species 

 and varieties, which are very useful either for conservatory 

 decoration, or for cutting for bouquet-making, most of 

 them being, moreover, fragrant, which is an additional 

 recommendation. They should be grown in a mixture of 

 peat and loam, in about equal parts, with a liberal addition 

 of sand. The plants should be kept close to the glass, to 

 prevent them from getting weak and straggling, and the 

 atmosphere should be kept charged with moisture, to pre- 

 vent attacks of the red spider (Acarus tellarius). If weU 

 grown, few plants are more attractive than Bouvardias, 

 their dense heads of Ixora-like flowers being very elegant 

 and ornamental. These plants are most readily propagated 

 by cuttings, which should be inserted in the same soil as the 

 old plants are grown in, simply covering with a little silver 

 sand. 



B. Alfred Xcuner. — This is a most distinct novelty, having 

 pure white double flowers ; it is of American origin, and is a 

 sport of B. Davidsonii. This will be found invaluable where 

 cut flowers are in great request. 



B. angustifolui. — This is a dwarf, free-flowering variety 

 of the old B. tri-phylla,, with neat foliage and trusses of 

 briUiant scarlet flowers. It comes from Mexico. 



B. Brilliant. — A garden variety of free-flowering habit, 

 producing a profusion of bright scarlet blooms in autumn, 

 and contrasting well with hghter-coloured kinds. 



B. carina. — A garden variety, resembling B. longiflora in 

 habit and general appearance, producing its fragrant delicate 

 flesh-coloured flowers in great profusion. 



B. ddicata. — The flowers of this kind are of a rich salmon
