V. COMPARISON OF THE KALAHAEI AND EASTERN 



MOUNTAIN FLORAS.* 



1. Orders occurring in the Kalahari which are not recorded from 

 the Eastern Mountain Region : 



Nymphaceae, Elatiueae, Ochnaceae, Connaraceae, Hamamelideae, 

 Rhizophoraceae, Lemnaceae, Mvrtaceae, Loasaceae, Plumbagiueae, 

 Pontederiaceae (each represented by one species) ; Malpighiaceae, 

 Burseraceae (each represented by 2 genera and 3 species) ; Tuue- 

 raceae (2 genera and 2 species) ; Combretaceae (2 genera and 13 

 species) ; Sapotaceae (3 genera and 5 species) ; Rutaceae (5 genera 

 and 6 species) ; Pedalineae (5 genera and 9 species) ; Bignouiaceae 

 (1 genus and 3 species) ; Plantagineae (2 genera and 2 species) ; 

 Loranthaceae (2 genera and 5 species) ; Haemadoracea (2 genera and 

 3 species). 



The most striking feature to be noted is the absence of the Com- 

 bretaceae and the Pedalineae, which are characteristic Kalahari 

 Orders. 



2. Orders occurring in the Eastern Mountain Region which are 

 not recorded from the Kalahari : 



Piperaceae, Restiaceae (1 genus and 1 species) ; Aroideae (1 yenus 

 and 3 species). 



3. Orders well represented in the Kalahari, but poorly represented 

 in the Eastern Mountain Region :
