with a tuft of hairs at the base and a terminal awn, beautifully plumose at the top. Mentioned here on account of the beautiful and curious flowers and seeds, and

follicles, and linear oblong seeds with a tuft of hairs at one or both ends. Calyx small, segments almost free ; corrolla salver-shaped, 5-lobed ; carpels 2, free ;

M. elastica, K. Sebum. Vern. name— 10, Imperati. A tall glabrous tree growing along streams throughout Magenja da Costa and Nhamacurra, and present also in 
Sofala and Manica, where Mr. Johnston has its qualities under observation. Seldom over 15 c.m. diameter of stem. Leaves oblong-elliptical, 10-12 c.m. long, 2 5-3 
c.m. wide, shortly petioled, somewhat narrowed below, and tapering to the 1 c.m. petiole. Inflorescence terminal, but by the development of one upper bud the 
fruit often appears lateral. Follicles 8-12 c.m. long, 1-5-2 c.m. diameter, bluntly 3-angled or cylindrical, green, glabrous, smooth, opening along their inner faces, 
many-seeded ; the seeds flat, brown, 1*5-2 c.m. long, 2-5 m.m. wide, with a large tuft of brown hairs at the upper end and a small tuft at the lower end. Yields 
rubber freely and produces about half of the rubber exported from where it grows, the Banyan traders giving the natives the same price for it as for Landolphia 
rubber, which is about equivalent to a penny for 4 balls. The tree is cut one day and on the next day the rubber is collected direct on to sticks. Sim 6021.

ADENIUM and PACHYPODIUM are 2 closely related genera, characterised by having the leaves spirally arranged and the stem succulent, and distinguished by 
the former having no spines while the latter has stipular spines. Both have the corolla funnel-shaped or campanulate, 4-5 c.m. long, and in local species bright
