PuNGO AxDOXdO.— A small tree of 5 to 8 ft. ; branohlets elongated ; 

 leaves ternate or opposite or quarternate ; juice viscid, at length elastic. 

 By thickets in wooded places along the stream Luxillo, sporadic ; 

 young fr. Feb. 1857. Probably the same species, but the leaves rather 

 narrower. No. 4651. 



The dioarpellary ovary presents some difficulty as to placing this 

 tree in the above genus, but the inclusion in the genus of P. bicarpellatcc 

 Stapf inKewBull. 1894, p. 21, helps to overcome it; moreover, the 

 fact that the ovary is unlobed for a considerable time and apparently 

 in some cases entire even in fruit suggests for it- the genus Acokanthera 

 Gr. Don ; its axillary inflorescence precludes its reference to Rauvolfia, 

 to which in many respects it approaches. 



5. DIPLOEHYNCHUS Welw. ex Ficalho & Hiern. in Trans. 

 Linn. See, ser. 2, ii. p. 22 (Dec. 1881) ; K. Schum. in Engl. Nat. 

 Pflanzenfam. iv. 2, p. 142 (Biplorrhynchus) (1895). 



Follicles 2 together; each obovate, sickle-shaped, falcately 

 diverging, beset on all sides with distant warts, rather broad at 

 the sessile base, shortly firmly and thickly beaked at the apex, 

 somewhat compressed, woody, very tenacious, bivalved in an 

 elastic manner, longitudinally dehiscing along the inner convex 

 ventricose edge, 3- or perhaps sometimes 4-seeded ; the valves 

 quite smooth inside ; seeds according in shape to the follicles and 

 parallel to its sides, compressed, extended downwards into a broad 

 membranous ovate-oblong obtuse vidng ; raphe dorsal, prolonging 

 the free funicle to the centre of one side between the seeds ; 

 endopleura thin, membranous, whitish, albumen sparse, fleshy, 

 white ; embryo obliquely reniform in the middle of the seed, 

 small, those of the two lateral (outer and inner) seeds being three 

 or four times larger; cotyledons deeply cordate, uneqvial, flat, 

 rarely with one or two inflected lobes ; radicle acutely conical, 

 oblique, directed towards the hile, small.

HuiLLA. — A small, lactescent tree, sometimes a climbing shrub or in 

 other cases a bush standing erect with one or two scandent branches r 

 leaves evergreen, coriaceous, glossy ; flowers white, very fragrant. In 

 the more elevated, hilly places near Nene, in company with Com- 

 bretacese ; fl. and fr. Oct. 1859. No. 6982. A much-branched bush, 

 6 to 10 ft. high ; branches sarmentose ; leaves evergreen, glossy, 

 broadly ovate ; flowers white, like those of a jessamine in shape and 

 very sweet fragrance, corymbose at the ends of the branchlets ; 

 follicles short, almost half-ovate, scarcely an inch long, woody, spread 

 out when quite ripe into a nearly flat disk ; seeds broadly winged, not 

 comose. In the small forests of Humpata ; fl. and fr. Oct. 1859 and 

 June 1860. Coll. Carp. 64. 



According to a note of Welwitsoh, this plant occurs also in the dis- 

 tricts of Cazengo and Pnngo Andongo, and is known by the name of 

 " Jasmin do Pereira de Cazengo." The following, represented by only 

 one specimen and consisting of a broadly obversely deltoid rugose 

 glabrous fruit, li in. long, 14 in. broad and 4 in. thick, perhaps belongs 

 here : — 



Puxoo Andongo.— A tree in leaf. At Tunda Quilombo in th& 

 prsesidium ; fr. Feb. 1857. Coll. Carp. 729.
