I873-] NOTES ON GREENHOUSE SHRUBS. 559 



in the hottest part of the day. Cuttings are somewhat difficult to 

 strike; but when they are attempted, the shoots should be just beginning 

 to harden, and be inserted in sand in a mild bottom-heat and a cool 

 atmosphere under a bell-glass. They usually produce seed; as many 

 of these as are wanted for propagation should be allowed to ripen, 

 and the rest removed so as not to tax the energies of the plant, which 

 after flowering should be allowed to be expended on the growth. 



B. conferta. — A close-growing twiggy plant of small growth, with 

 smooth simple linear leaves densely crowded on the branches. The 

 flowers are violet, produced in clusters at the extremities of the 

 branches, and appear in early summer, and last till late. It belongs to 

 the family Leguminosse, and is a native of S.W. Australia. 



B. indcliella. • — Like the last, this sort is twiggy in habit, and the 

 branches are closely clothed with narrow linear sharp-pointed leaves, 

 and with a grey-green powder. The flowers are borne in the axils 

 of the leaves, chiefly at the extremities of the branches. They are 

 purple, and appear in the spring months. Native of Swan River. 



Callistacliys. — This is a group of easily-cultivated and handsome 

 shrubs. They are of rather free and vigorous habit, and consequently 

 better adapted for furnishing large greenhouses and conservatories 

 than small ones. Sandy loam and fibrous peat, the former predo- 

 minating, is an agreeable compost to them. A temperature of 40° to 

 45° in winter suits them best. They belong to the order Leguminosse, 

 and are natives of New Holland. 



C. lanceolata. — This sort grows to the height of 3 or 4 feet. The 

 leaves are opposite, usually in threes, acutely lanceolate, and fringed 

 with fine silky hairs. The flowers are yellow in terminal spikes, and 

 open in summer from May or June till August. 



C. ovata. — This is of closer growth than the last, but equally vigor- 

 ous. The leaves are ovate, broader at the point than the base, pro- 

 duced in opposite threes, and silky on the under side. The flowers 

 are yellow in terminal clusters, opening about the same season as the 

 last. 



C. longifolia. — This is one of the largest growing and most vigorous 

 of the group. It has long lanceolate leaves, and terminal spikes of 

 yellow and purple flowers, which appear in summer. 



C. retusa. — This sort is dwarf, and rather diffuse in growth. The 

 leaves are obovate, the points very blunt, and terminating in a fine spine- 

 like point. The flowers are reddish, in terminal spikes, and appear 

 in the summer months, 



C, linearis. — This grows with nearly as much vigour as longifolia. 

 The leaves are linear, distinctly netted. The flowers are yellow, in 

 loose terminal spikes, and open in the autumn months. W. S,
