LIST OF GREENHOUSE SHRUBS. 
179 
by cuttings of the roots, which should be planted in pots filled with heath mould 
and loam, plunged in a little heat, and covered with a glass ; for general culture 
see Bouvardia trlphyUa, Vol. I. page 225» 
BEAUFORTIA. 
B. DECussATA. All the species of this genus are splendid ; they flourish in a 
soil composed of three-parts sandy heath mould and one part light loam ; they grow 
very freely in the conservatory, and are increased by cuttings of the ripe wood, 
planted in sand, plunged in heat, and covered with a glass. 
BRUGMANSIA. 
B. BicoLOR, or SATSIGUINEA. This splendid species is a native of South 
America, where it is found growing amongst rubbish upwards of 7000 feet above 
the level of the sea. It is a very free-growing plant, and should be placed in a 
warm part of the conservatory, and treated in the same manner as B. suaveolens. 
It is easily propagated by cuttings, planted in pots of soil, and plunged in a brisk 
heat under a glass. 
BURTONIA. 
B. coNFERTA. This plant is rather difficult to keep, from its liability to damp 
off ; it requires a dry airy situation in the greenhouse, and to be well drained with 
potsherds, as the least stagnation of water will cause it to perish. The soil most 
suitable is composed of three parts sandy heath mould and one part loam, with a 
little leaf mould. Cuttings of the tender wood planted in pots of sand, under a 
glass, and treated like erica cuttings, will soon strike root. Seeds are also 
occasionally produced, which should be sown as soon as ripe. 
BORONIA. 
B. SERRULATA and DENTicuLATA are both very handsome little shrubs ; for 
their culture see Vol. I. page 173. 
CROWEA. 
C. SALIGNA. This is a very interesting plant, with fragrant leaves, and a very 
free flowerer, continuing in bloom during the whole summer ; it requires a dry airy 
situation in winter, or it is liable to suffer from damp. It is increased by cuttings, 
treated in the same manner as those of Boronia, and should be potted in peat. 
CHORIZEMA. 
All the species of chorizema are short-lived, but very beautiful ; they require 
a little more heat than the generality of New Holland plants ; they also thrive best 
if slightly shaded by other plants, as the full power of the sun is very apt to change 
the bright colour of the leaves. They are increased by cuttings of half ripened 
wood, and by seeds ; for further particulars see Vol. II. page 171. 
CAMELLIAS. 
For the treatment of these see Vol. I. page 32, and Vol. II. pages 25 and 73. 
CALLISTACHYS. 
C. LANCEOLATA. This is a quick growing, very handsome plant, very suitable 
for a large conservatory. It is a native of New Holland, from whence it was 
introduced in 1814. It is easily increased by seeds, which are produced plentifully ; 
also by cuttings planted in either sand or soil, and covered with a glass. A common 
mixture of loam and heath mould suits it well.
