![IX. DILLENIACEjE. Tetmcera] 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, Sertum Angolense, p. 30, observ.). 1. T. obtusata Planch, ex Oliv. PI. Trop. Afr. i. p. 12. T. alnifolia DC. Syst. Veg. i. p. 401 (1818), non Willd. 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 insufficient to make this identification certain. 2. T. alnifolia Willd. Sp. PL ii. p. 1243 (1799); Oliv. FI. Trop. Afr. i. p. 12, cum syn., non DC. T. Guillemini Steud. Nomencl., edit. 2, ii. p. 670 (1841). T. Potatoria Afz. ex Steud., l.c. Golungo 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. 3. T. Boiviniana Baill. in Adans. vii. p. 300 t. 7 (1867); Oliv. FI. 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 Anonacese 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 Monodor a, the “ Gipepe ” of the natives, are the most notable (Welw. Apont. p. 554). The Anonacese, by their luxu-](https://iiif.wellcomecollection.org/image/b28120486_0001_0039.jp2/full/800%2C/0/default.jpg)
