LAURACEAE 227 



The laurel, Laurus 7tobilis, is often grown in South 

 African gardens (bay leaves), and the camphor tree, 

 Cinnamomum Camphora, forms beautiful avenues on some 

 of the old farms in the Stellenbosch district.

MENISPERMACEAE (page 223). 



Antizoma capensis. This plant is usually included in the genus Cissampe/os, 

 apparently owing to an oversight, for although the description in the Flora 

 Capensis (Vol. 1, p. 10) states that there is only one petal, we have always 

 found two (see Fig. 99), hence we agree with Diels who refers this species 

 to the genus Antizoma. 



The plant is a shrubby twiner, growing in bushy places in various parts 

 of South Africa. Dioecious ; the male shrubs appear to be far more numerous 

 than the others. Fruit a yellow drupe with a flat stone. 



As in most climbers the wood of the stem and root is traversed by 

 numerous large air channels which wind about in a very irregular way. 



The root is largely used by the colonists as a blood purifier instead of 

 sarsaparilla and goes under the name " davldjes wortel."
