The Heath Family. 



This order contains some 1000 species, divided into 

 5 tribes ; but only one tribe is represented in South 

 Africa, containing 10 genera, of which the Heaths are 

 some 500 in number, and very characteristic of the dry 

 climate of south-west districts. Indeed,* the foliage is 

 imitated by many other plants which do not belong to 

 the family at all. 



The tribe Fricece is divided into two sub- tribes — 

 Fuericece, in which the ovary is four to eight-celled, there 

 being two or more ovules in each cell, of which the 

 true Heaths are the best example ; the other sub-tribe 

 is Salaxidece, named after the genus Salax'is, in which 

 the ovary is one- to four-celled and the cells one-ovuled.
