1. TETRACERA L. ; Benth. & Hook. f. Gen. PI. i. p. 12. 

 The same connection between station and habit is manifested 

 in this genus as in Clematis, the species of the shady forests of 

 lower Angola being widely scandent, whereas that of the interior 

 elevated region has a short erect or ascending stem. (See 

 Welwitsch, Sertiim Angolense, p. 30, observ.).

Sierra Leone. — A tall and widely climbing shrub ; leaves mostly 

 cuspidate ; at the base of Sugar Loaf Mountains, near Freetown ; 

 without flowers or fruits Sept. 1853. No. 1205. 



The specimen is insufiicient to make this identification certain.

GolunCtO Alto. — A robust climbing shrub ; trunk 2-| in. in diam* 

 at the base, twining, spirally embracing the trunks of other trees ; 

 branches sarmentose to a great distance ; leaves repand-dentate or 

 toothed. In the more elevated forests of the mountains of Serra de 

 Alta Queta, rather rare ; in flower and young fruit 21 May 1856 ; also 

 at Sange, 23 May 1856 ; in company with Dichapetalum angolense 

 Chodat (Welw. Herb. No. 4664). No. 1203.

 Fl. Trop. Afr. i. p. 13; variety with glabrous carpels. 



PuNGO Andongo. — A shrub, 1 to 3 ft. high ; stems numerous from 

 the crown of the woody rootstock ; branches erect or ascending ; leaves 

 rigidly coriaceous, rather rough on the upper surface ; flowers white, 

 large, fragrant ; carpels dark, shining. In thickets on sandy clay, 

 between the rivers Luxillo and Cuanza, sporadic ; in flower and young 

 fruit, or occasionally barren, in the middle of Dec. 1856. No. 1206. 



This plant is apparently the shrub alluded to by Welwitsch, Aponta- 

 mentos, p. 554, as probably a new genus. 



4. Tetracera, sp. ? 



GoLUNGO Alto. — A stout shrub, climbing far and widely ; branches 

 very long, winged in some parts ; leaves deciduous, having the shape, 

 size and margins of those of a chestnut. In dense, especially shady 

 forests of the mountains of Serra de Alta Queta ; without either flowers 

 or fruits. May 1856. No. 1204. 



III. ANONACEiE. 



The Anonaceae seldom descend to the coast region, and then 

 only along the banks of the large rivers, but chiefly abound in 

 the hilly and lower highland regions, where they enliven the 

 primitive forests with the glossy verdure of their foliage, and 

 with the gracefulness of their habit; many of them are fine 

 climbers, and others form majestic trees, among which two 

 species of Monodora, the " Gipepe " of the natives, are the most 

 notable (Welw. Apont. p. 554). The Anonacese, by their luxu-
