318 XLiv. LEGUMiNOSiE. [Albizzia 



wood is very light and rather smooth, and presents at times purple or 

 rose-coloured veins in the centre of the trunk. The name is also 

 applied to Acacia pennata Willd. and Albizzia fastigiata Oliv. 



The following three Nos. apparently belong to Leguminosse, 

 sub-order Papilionaceae ; the first is poorly represented in the 

 British Museum set, and the two latter seem to belong to a species 

 of a genus allied to AmeriTnnon : — 



HuiLLA.— Style glabrous, tumid at the base ; keel blunt. Cf . Shuterla 

 (Baker ms. in Herb. Welw,). Peduncles elongated and fasciculate. 

 In wooded thickets at Mumpulla ; fl. Oct. 1859. No. 4125. 



GoLUNGO Alto.— A young tree of 8 ft. or of 15 to 20 ft. ; branches 

 erect-patent, rigid ; branchlets somewhat pendulous ; leaves irregularly 

 pinnate, sometimes simple or reduced to the last leaflet, dry-coriaceous, 

 very rigid, quite glabrous ;_ leaflets alternate, thick but not fleshy, very 

 large, delicately veined, veinlets anastomosing in a rectangular manner, 

 spaces between the veinlets more or less square, obscurely pellucid- 

 punctate, margins broadly cartilaginous. Sporadic, in primitive forests 

 near the spring of Quibolo in Serra de Alto Queta ; always without 

 either fl. or fr. Feb., March, June and August 1856. No. 1887. 



Cazengo.— Sent from Caculo by Senr. Candido under the name of 

 "Mubafo," but it is not the true Mubafo which is CanarhDn edule 

 Hook. f. (Welw. No. 4483) ; leafy branch of a tree much damaged by 

 insects, July 1855. No. 1887&. 



XLV. ROSACEA. 



The comparative scarcity of this Order in Western Tropical 

 Africa, which had been previously commented on, was entirely 

 confirmed by Welwitsch's careful investigations in Angola. The 

 plant producing the pigeon plum of Afzelius, called " Jingimo" or 

 "Jinginvo" by the natives, grows abundantly along the coast, 

 sometimes in the form of a low bush as in Mossul and Ambriz, 

 and sometimes it is a small elegant tree as in the islands of Loanda 

 and Cazanga ; the fresh leaves abound in an astringent substance ; 

 the ripe fruit reaches the size of a small tangerine orange and is 

 reddish-purple or black-purple, and also slightly succulent and 

 somewhat astringent; there is, however, a yellow variety. A 

 rose, probably a variety of Rosa gallica L., is cultivated in the 

 gardens and fields of the colonists in many parts of the province ; 

 it does not much enjoy the coast region, but thrives fairly well in 

 the hilly region and perfectly in the highlands, especially on the 

 confines of Pungo Andongo. Welwitsch recommended the intro- 

 duction of the Abyssinian tree, Hagenia ahyssinica Gmel., called 

 " Cusso " or " Cabotz," of which an infusion of the flowers furnishes 

 a sure remedy in cases of tape- worm ; he also recommended the 

 cultivation of the strawberry (morangos) on the banks of the rivers 

 Bengo and Dande in the coast region and in moist fields and shady 

 places in the hilly and highland regions; and the introduction, 

 especially by the rivers Bengo and Dande, of the Brazilian tree 

 Licania Jlorilnmda Benth., the fruit of which is much valued for 

 dessert and is called "Guiti" or " Oiti" by the Brazilians.
