FLOWERING TREES AND SHRUBS 27 



it is just as well to give so choice a shrub the slight pro- 

 tection afforded by a wall. The leaves are opposite, thickly 

 arranged, and hoary-grey ; while the whole plant is twiggy 

 and of strict though by no means formal growth. Flowers 

 lavender-blue or violet, borne in the leaf axils at the tips of 

 the shoots, and appearing in succession for a considerable 

 length of time. Light, sandy peat would seem to suit it 

 well ; at least, in such it grows and flowers freely. There 

 is a white-flowered variety. 



Cassandra (Ericaceae)* See Andromeda, 



CASSANDRA CALYCULATA (syn Andromeda calyculatd). 

 North America, 1748. This is a handsome species from 

 the Virginian swamps, but one that is rarely seen in a very 

 satisfactory condition in this country. It grows about 

 18 inches high, with lanceolate dull-green leaves, and 

 pretty white flowers, individually large and produced 

 abundantly. For the banks of a pond or lake it is a 

 capital shrub and very effective, particularly if massed in 

 groups of from a dozen to twenty plants in each. There 

 are several nursery forms, of which C. calyculata minor is 

 the best and most distinct. Light peaty soil. 



Cassia (Legumtnosae), 



CASSIA CORYMBOSA. Buenos Ayres, 1796. A half-hardy 

 shrub that in this* country succeeds best when planted 

 against a wall, and in a sheltered, sunny situation. The 

 flowers are both beautiful and conspicuous, being of a 

 showy yellow colour, and, when the plant is established 

 in a suitable site, very freely produced. Sandy peat or 

 leaf-soil seems to suit it well. 



Cassinia (Compositae)* 



CASSINIA FULVIDA (syn Diplopappus chrysophyllus). New 

 Zealand. This is a neat-growing and beautiful shrub, the
