aromatic, excellent. No. 3524. A small tree, 8 to 15 ft. high, or even 
more, forming, together with another kind of tree, little forests in 
Sobato de Mumpulla, abundant ; fl-bud and male and female fl. Oct. 
1859. A species of Viscum grew on this tree. Nos. 3522 and 6745. 
In the male flowers the involucre 4-lobed, with broadly ovate lobes ; 
corolla white, 5- or very rarely 4-lobed, shaggy outside, smooth 
inside ; stamens 5, exserted ; style far exserted, rather fleshy ; stigma 
scarcely divided ; ovary abortive ; nectary apparently none. Local 
name ‘“‘ Pfo Quicongo.” Nos. 3523, 3525-7. 
(Quicongo 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 (Parinari Mobola) and some species of Leguminose and 
Proteaceze, constitute the principal part of the forest in the delightful 
plateau of Huilla; it occurs most abundantly from 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 quitandas 
(markets) on the coast, and fragments of it are suspended from the 
necks of nearly all negro travellers in Angola. (Welw. Synopse, p. 16,
