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 Linncua, xxiii. 78. A tree, 30-40 ft. 

 high, quite glabrous ; young branches terete, stout, blackish or brown

 petiole 2-12 lin. long, stout. Cymes very dense, at the ends of the 

 secondary rays of large umbels ; peduncle 2-3 J in. long, stout ; primary 

 rays 1-2 in. long ; secondary rays 3-G lin. long ; pedicels in flower up

Also in Natal. 



A plant collected by Boehm and Reichardt in Kavende, Western German East 

 Africa, an I distributed as Voacanga angustifoUa, K. Sclmm. (ined.), belongs either to 

 R. caffra or to a new species nearly allied to it. I have only seen a leaf and a fruit 

 of it. Tiie 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 tleshy obscurely and asymmetrically 

 obcordate twin drupe with 2 unequal pyrenes, over ^ in. long and across. 



Another specimen collected by Kirk between Shibisa and Tshinmuzo, in Nyasa- 

 land, between 2000 and 4003 ft., agrees with R. nataleasis in the inflorescences and 

 flowers, but the leaves are relatively broader (3 times as long as broad), not quite so 

 firm and more distinctly reticulated; they are nearly all detached and mutilated.
