CASSIA 87 



semi-hardy species not often met with. One of the finest 

 is C. (Poinciana) pulcherrima, the Barbadoes Fence-Flower, 

 a great favourite in the tropics, but not much grown by 

 English gardeners. They are not easy to propagate, but 

 cuttings placed under a bell-glass in heat are likely to 

 succeed. 



CALYSTEGIA 



Bearbind. Hardy herbs, nearly related to Convolvulus. 

 They are of easy cultivation, and should be trained up wires 

 against a wall or provided with pea sticks. Propagation 

 by means of the underground runners or by seeds. The 

 best are C. hederacea, v&r.florepleno, which has pink flowers ; 

 C. sylvatica, white flowers, and its rose-coloured variety. 



CANTUA 



Scandent South American shrubs, usually trained against 

 walls or pillars in the greenhouse ; although C. buxifolia 

 (dependent), which has tubular, red flowers, produced in 

 drooping clusters at the ends of the branches, may be 

 planted out in sheltered positions in the mildest districts. 

 C. bicolor has short-tubed scarlet and yellow flowers. The 

 plants are of fairly easy culture, and are propagated by 

 cuttings inserted in sandy soil under a hand-glass. 



CASSIA 



An extensive genus of yellow-flowered leguminous 

 shrubs and herbs, few members of which are in cultivation 

 in gardens. The best-known species, C. corymbosa from 

 Tropical South America, forms a large bush, with dark
