666 LXXXII, APOCYNACES. [ Pleiocarpa 
Punco ANDONGO.—A small tree of 5 to 8 ft. ; branchlets 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. 4551. 
The dicarpellary ovary presents some difficulty as to placing this 
tree in the above genus, but the inclusion in the genus of P. bicarpellata 
Stapf in Kew Bull. 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 
G. Don ; its axillary inflorescence precludes its reference to Rauvoljia, 
to which in many respects it approaches. 
5. DIPLORHYNCHUS Welw. ex Ficalho & Hiern. in Trans. 
Linn. Soc., ser. 2, ii. p. 22 (Dec. 1881); K. Schum. in Engl, Nat. 
Pflanzenfam. iv. 2, p. 142 (Diplorrhynchus) (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 wing; 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, unequal, flat, 
rarely with one or two inflected lobes; radicle acutely conical, 
oblique, directed towards the hile, small.

Huiiia.—A small, lactescent tree, sometimes a climbing shrub or in 
other cases a bush standing erect with one or two scandent branches : 
leaves evergreen, coriaceous, glossy ; flowers white, very fragrant. In 
the more elevated, hilly places near Nene, in company with Com- 
bretacez ; fl. and fr. Oct. 1859. No. 5982. 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. Coun. Carp. 64. 
According to a note of Welwitsch, this plant occurs also in the dis- 
tricts of Cazengo and Pungo 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, 14 in. long, 1% in. broad and ¢in. thick, perhaps belongs 
here :— 
Punco Anponco.—A tree in leaf. At Tunda Quilombo in the 
presidium ; fr. Feb. 1857. Coun. Carp. 729.
