CISSUS 89 



dull-coloured flowers of singular form. They are not 

 common in gardens, their flowers appealing only to those 

 who find interest in queer things. There is a good collec- 

 tion of them at Kew, where they are grown on rafters or on 

 trellises. The showiest are C. elegans, C. Monteiroce, C. 

 Sandersonii, C. Thwaitesii, and C. stapeliceformis. They like 

 a moist, warm house and partial shade. 



CESTRUM (see Plate XIX) 



Ornamental stove, greenhouse, and half-hardy shrubs, 

 some of which are known as Habrothamnus. The favourite 

 greenhouse species are C. elegans (see Plate XIX), which has 

 downy branches and leaves, and red-purple flowers, freely 

 produced in large terminal cymes ; C. Newellii, much like 

 C. elegans y but with scarlet flowers ; and C. aurantiacum, 

 with glabrous leaves and golden flowers in terminal 

 panicles, produced in winter. Of easy culture, they 

 should be spurred hard back after flowering. They are 

 excellent for planting in greenhouses, to cover walls or 

 pillars, and they repay generous treatment. They are pro- 

 pagated from cuttings taken in summer. 



CISSUS 



This genus is characterised by cymes or corymbs of 

 small, greenish, yellow, or purplish flowers, and simple 

 trifoliate or palmate leaves. Some authorities have sunk 

 it in Vitis ; but it is certainly better for gardeners to con- 

 sider it distinct. The foliage of C. discolor, a native of Java, 

 is a bright, velvety green, beautifully mottled with white, 

 the under side deep reddish-purple, and the stems coral 

 red. With generous treatment it is one of the best stove
