secondary rays $ in. long, Calyx not quite }$ lin. long, cup-shaped, 
\-toothed. Corolla whitish; tube 14 lin. long, villous at the mouth; 
lobes very broad, ovate, subacute, small. Carpels connate at the base; 
style glabrous, less than 1 lin. long. Fruit a more or less obcordate

Lower Guinea. Angola: Pungo Andongo; common by streams, Welwitsch, 
5951! 
Welwitsch, 5952 from the Tangue River, Angola, is very similar in foliage to 
Welwitsch, 5951, but the fruit accompanying it belongs evidently to a species of Cono- 
pharyngia. 
4. R. natalensis, Sond. in Linnea, xxiii. 78. A tree, 30-40 ft. 
high, quite glabrous; young branches terete, stout, blackish or brown 
when dry. Leaves in whorls of 3-4, oblanceolate, acute or subacuminate, 
long attenuated towards the base and more or less decurrent on the 
petiole, 5-12 in. long, 14-22 in. broad, firmly membranous, pale dull 
green; secondary nerves 18~30 on each side, slightly curved, sub- 
horizontal; veins quite obscure, or very faint, loosely anastomosing ; 
petiole 2-12 lin. long, stout. Cymes very dense, at the ends of the 
secondary rays of large umbels; peduncle 2-34 in. long, stout ; primary 
rays 1-2 in. long ; secondary rays 3-6 lin. long; pedicels in flower up 
to } lin. long, in fruit up to 1 lin. long. Calyx } lin. long; lobes 
broad, ovate, subacute. Corolla-tube about 2 lin. long, densely villous 
at the mouth; lobes small, rounded. Carpels connate at the base or 
half-way up in flower. Fruit a more or less obovoid or subglobose 
drupe, 4 lin. long (semimature).—K. Schum. in Engl. & Prantl, Pflan-

Also in Natal. 
A plant collected by Boehm and Reichardt in Kavende, Western Ger man East 
Africa, an {distributed as Voacanga angustifolia, K.Schum. (ined.), belongs either to 
R. caffra or to a new species nearly allied to it. I have ouly seen a leaf and a fruit 
of it. The leaf is linear-lanceolate, acuminate, long attenuate into a short stout 
petiole, over 7 in. long, slightly over 1 in. broad, with about 10-20 very delicate 
curved secondary nerves. The fruit is a very fleshy obscurely and asymmetrically 
obcordate twin drupe with 2 unequal pyrenes, over 4 in. long and across. 
Another specimen collected by Kirk between Shibisa and Tshinmuzo, in Nyasa- 
land, between 2000 and 4000 ft., agrees with R. natalensis in the inflorescences and 
flowers, bat the leaves are relatively broader (3 times as long as broad), not quite so 
firn and more distinctly reticulated ; they are nearly all detiched and mutilated.
