Golungo Alto. — A tree, 20 to 30 ft. high, with fastigiate branches 

 and dilated umbrella-shaped crown ; flowers whitish. Common in the 

 more elevated forests of Serra de Alto Queta ; in young fr. June 1856 ; 

 Zengas, with fl. and ripe fr. on the same tree, 18 Sept. 1856. No. 1769. 

 A tree, 20 to 25 ft. high ; branches dichotomous, fastigiate, the upper

 leaves not uncommonly 8- jugate ; leaflets somewhat pilose also on the 

 upper surface ; jugal glands always present between the last 3 to 5 pairs 

 ■of leaflets ; corolla white ; stamens of the central flower of each head

Golungo Alto. — A shrub of 5 to 7 ft., perhaps becoming a tree ; 

 leaflets whitish-glaucous. In the denser woods, near the cataract of 

 the river Cuango, not far from Sange, with foliage without either fl. or 

 fr. beginning of August 1855. No. 1772. A small mutilated shrub, 

 5 ft. high, with a little trunk scarcely 1-J in. thick and leafless branches 

 bearing young fl. ; in the same spot as No. 1772 and perhaps belonging 

 to the same species ; Sept. 1856. No. 17726. A tree 25 ft. high, 

 branched in a fastigiate manner. Sporadic, in the primitive forests of 

 Mata de Quibanga, near Sange, where Morus excelsa Welw. No. 1559 was 

 first seen in flower by Welwitsch ; in leaf without either fl. or fr. Ded 

 1855. Perhaps the same species as Nos. 1772 and 17726. No. 1773. 



These three determinations are doubtful.

Golungo Alto. — A lofty tree, 20 to 30 ft. high or more, usually 40 

 to 45 ft. high ; branches patent, ascending-fastigiate ; crown truncate- 

 dilated at the top ; wood durable ; flowers yellow-greenish or from 

 whitish to pale straw-coloured ; the central flower of each head (as in 

 all the species of the section Zygia) always sterile and different in form 

 from the rest. Yery abundant in the mountainous forests of the whole 

 district, distinguishable from afar by the singular obconical shape of 

 the crown ; at Trombeta, Cungulungulo, Bumba, and Sange ; fl. Nov. 

 1854 and Jan., fr. Oct. 1854 and August 1856 (at Zengas do Queta) ; 

 nearly always either in fl. or fr. Native name " Muanze." No. 1770- 



Pungo Andongo. — A tree, 20 ft. high ; crown fastigiate, dilated in 

 the form of an umbrella ; branchlets and petioles densely puberulous ; 

 the extreme leaflets the largest ; flowers whitish. Sporadic, in small 

 open rocky woods on the north side of the fortress of Pungo Andongo ; 

 fl. Dec. 1856. No. 1771. 



The last No. (1771), of which no flowers were separated for the 

 British Museum, seems to approach A. fastigiata Oliv. 



This is apparently the tree referred to by Welwitsch in Synopse, 

 p. 14, n. 34 and p. 36, n. 98, under the name of "Muance," which 

 he describes as a species of Zygia and one of the most abundant 

 constituents of the virgin forests of the district of Golungo Alto ; its
