 In the primitive forests of Sobato Cabanga-Cacalungo ; fr. 3 Feb. 1855.

 the apex with two bifid connivent styles or stigmas or with their 

 remains (the stigmatic lobes divaricate) ; young seed pendulous from 

 the top of much larger cavity of the young fruit ; ripe fruit cinnabar- 

 red, drupaceous, juicy, monopyrenous ; seed bony, quadricostate, 

 cotyledons plicate ; radicle thick. In hilly bushy places in Sobato 

 Bumba, near Bumba, fr. 2 May 1855 ; also at the outskirts of forests 

 among the Bango and Queta mountains, S. and young fr. 12 Nov. 1855. 

 Native name " Quib4ba." No. 6298. In fl.-bud and young fr. No.

 The following No. should be compared with this species : — 

 Island of St. Thomas. — Called " Capitao." Without fl. or fr. 

 No. 6303. " Capitao " is used for joinery, turning, and building (see 

 Cat. Exposit. Paris 1867, sect. Portug. p. 427 n. 14). 



" Quibaba roxa " or Red Quibaba is a tree 60 to 100 ft. high, which 

 grows in groups constituting the bulk of forests and forms one of the 

 finest ornaments of the virgin forests of Golungo Alto and Cazengo ; 

 its trunk is always straight, and not uncommonly attains a height of 

 60 ft. and more, nearly cylindrical to the height often of 40 ft., with 

 a diameter from 2 to 2^ ft. at the base ; the bark is whitish grey, and 

 the wood is nearly but not quite always cherry-red or blood-red in the 

 middle and white towards the outside ; the head is rather lax, and the 

 leaves variable in shape and substance. Welwitsch had no oppor- 

 tunity of witnessing any application of it made by the natives ; 

 he regarded it as a new species of Sponia (see Welw. Synopse Explic. 

 p. 12. n. 25 [1862] ). It doubtless is this and possibly also the 

 previous species of Celtis. The " Quibaba " of Mussengue or of Hungo 

 is Khaya anthotheca CDC. ; ante, p. 135. The " Quib&ba " of Queta or 

 " Quib&ba quina " is £retojidr'qp^rag'ma angolense C.DO. ; ante, p. 136. 

 '' Quibeba" is Ficus Quibeba Welw. herb. no. 6399. The Bunda name 

 " Quibaba," plural " Ibiba," signifies in general the bark of any tree 

 whatever, and is used in G-olungo Alto for trees of quite distinct 

 families. It was probably on the branchlets of the heads of this tree 

 that the lichen n. 156, Placodium Brebissonii, var. microspora Wain., 

 grew in the Sange forests in April 1856 ; also lichen nn. 203 and 204.

LiBONGO. — A tree, 20 to 30 ft. high, sometimes only 15 ft. ; head 

 wide ; branches spreading ; branchlets crowded, somewhat drooping ; 

 leaves coriaceous, shining, trinerved after the fashion of the Melasto- 

 macese. In rather dense forests at the banks of the river Lifune near 

 the petroleum mine, sparingly ; fr. end of Sept. 1858. No. 6302.
