 induplicate at the apex, with little horns proceeding from their folds. 

 In dense mountainous forests, especially by streams near Fonte de 

 Capopa, about Sange ; fl. 1 Dec. 1854. No. 3204. A shrub of 2 to 

 4 ft.; bi'anches rather erect, the fresh branchlets marked with two 

 longitudinal lines of hairs and a little compressed below the inter- 

 nodes ; leaves subcoriaceous, black-green and very glossy above, pallid 

 beneath ; corolla white, pentamerous, tubular ; the limb 5-cleft, 

 recurved-spreading at the time of full flower ; the throat bearded ; 

 stamens 5, inserted at the throat, exserted ; filaments bearded at 

 the base ; anthers cordate, white, introrsely 2-celled, longitudinally 

 dehiscing ; ovary three-quarters covered by the quinquedentate calyx ; 

 style filiform, bilobed at the apex ; the lobes more or less spathulate, 

 rather thick, stigmatose inside, sub-exserted. On slopes at the out- 

 skirts of forests on the left bank of the river Cuango ; fl. 5 June 1855. 

 No. 3205- A form with denser inflorescence. No. 3205&. A shrub, 

 1^ to 2 ft. high ; branches bent, very slender ; berries red-vermilion, 

 2-seeded ; seeds depresso-hemispherical. In dense forests among the

PuNGO Andongo. — A climbing shrub ; leaves coriaceous, deep- 

 green, paler beneath ; corolla from whitish to flesh-colour, with a 

 curved tube ; stamens placed together in one part of the corolla-tube 

 during the time of full flower, the opposite part of the tube being 

 occupied solely by the style. By rocky thickets in the fortress, 

 rather rare ; fl., middle of Nov. 1856. No. 3198. A widely scandent 

 shrub, with purple flowers. By thickets on the western side of the 

 prajsidium ; fl. Jan. 1857. No. 3199. 



This species is dimorphic, the anthers being only half exserted with 

 the style long and exserted in the first No., and the anthers wholly 

 exserted with the style short and included in the second No. ; it is 

 referred with some doubt to the name above, which belongs to a 

 Gaboon plant collected by Soyaux, n. 212 ; I have not seen a type 

 specimen of it ; our specimens agree fairly well with the description 

 as quoted, but the leaves do not exceed 5 in. long by '2^ in. broad, 

 the petioles range only up to | in. long, and the absence of fruit 

 renders it impossible to compare the size of the disk at the apex.

A small glabrous rather glossy tree ; branches sub-terete,
