africana, and Copaifera coleosperma. South of 

 this zone and as far as the sixteenth degree of 

 longitude (50 miles east of the Cunene) the forest 

 consists largely of Copaifera Mopane (Mutiati), and 

 the acacias (A. Kirkii, A. albida, and A. hebeclada) 

 towards the south ; but with a greater variety of 

 trees towards the north-east. Both baobabs and 

 Ilyphwnes are found in this zone. To the east 

 of the sixteenth degree of longitude and south 

 of the Berlinia zone the baobab disappears and 

 the forest consists of Copaifera coleosperma 

 (Muchibi), Burkea africana (Mukalati), Baikicea 

 plurifuga (Umpapa), and Hyphcenes, chiefly H. 

 Ventricosa, the dum palm. 



Welwitsch, whose observations on Angola are 

 incomparably the most valuable even now (seventy 

 years after they were made), did not devote the 

 same attention to the south as to the north of the 

 country. The plants he describes are nearly all 

 round Huilla, Humpata, and Tripollo and Bombo 

 that is, on the western edge of the vast plateau 

 which stretches to the Zambezi. Herminiera Ela- 

 phroxylon grows in marshy parts of the Huilla 

 plateau, as does Pterocarpus erinaceus, called Mira- 

 hondi in the north but Munhaneca near Humpata. 

 Many varieties of Ficus, for example, F. psilopoga, 

 and F. trachyphylla, occur. Among the Rubiaceae, 

 Adina micro cephala, var. Galpini (Mohanbo), is a 

 huge tree with oily, hard timber. The huge 

 Lonchocarpus macropliyllus (Mutula mena), Pelto- 

 phorum africanum (a tree 20 to 30 feet high, look- 

 ing like a mimosa), Berlinia paniculaia (Prnda), 

 and B. Baumii (Mumue) form forests towards the
