(}uicotigo is a name used in a collective sense in the markets at 

 Benguella, Loanda, and Ambriz, for various aromatic woods. The 

 Quicango of Huilla is a tree which, in company with that called Nocha 

 or Noxa {Purinari Mahula) and some .species of Leguminos.'u and 

 ProteacefB, constitute the principal part of the forest in the delightful 

 I^lateau of Huilla ; it occurs most abundantly fi'om the top of the 

 Serra de Xella to the neighbourhood of the great lake of Ivantala,. 

 forming in some places by itself extensive forests which recall the 

 olive woods in Portugal ; the greatest height here attained by this 

 tree is "20 to 25 ft. with its trunk rarely exceeding a foot thick ; but 

 there is reason to expect that, as with the other constituents of the 

 forest, it would under other circumstances become more developed and 

 assume larger dimensions. The principal causes of the successive 

 checks on the arboreal vegetation of these regions are not only the 

 destructive forest fires which the natives annually make for the purpose 

 of obtaining succulent pasturage for their numerous flocks of sheep, 

 but also the repeated invasions of the Munanos, whose vast encamp- 

 ments are always constructed at the cost of the extensive forests. 



The timber is of an olive colour, becoming sometimes dark brown 

 or dark purple, of fine grain, very compact and durable, and thus very 

 suitable for turnery, furniture, and other domestic articles, with the 

 special recommendation of a camphor-like aroma, which enables the 

 natives to prepare tonic and stomachic infusions from its powder, so 

 that it is met with under different names in nearly all the qu'daxda^ 

 (markets) on the coast, and fragments of it are suspended from the 

 necks of nearly all negro travellers in Angola. (Welw. Synopse, p. IG,
