FLOWEEING TEEES AND SHEUBS 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 (Leguminosae). 



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 (Composite). 



Cassinia fulvida (syn Diplopappus chrysophyllus). — New 

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