Var. /3 sclerophylla, Stapf. Leaves more coriaceous, with slightly revolute 

 margins and no distinct outer marginal nerve. Flowers larger ; corolla-tube 6-7 lin. 

 long; lobes 4 1- 5 lin. long. Ovary gradually passing into the style. — C. viscijlua,

Hallier describes the fruit (which I have not seen) of Dinklage, 1161, as globose, 

 over 2 in, in diam., dotted with minute warts, with a hard pericarp and numerous 

 seeds up to 8i lin. long. There is also, apart froiji tlie differences .mentioned above, 

 a difference in the faciesof this variety, suggesting a more than varietal rank. 



9. C. Staudtii, Stapf. A scandent shrub, glabrous except the 

 inflorescences. Young branches rather slender, brown or blackish 

 when dry, smooth ; lenticels few and minute. Leaves lanceolate to 

 oblong, acute or subcuneate at the base, abruptly acuminate (acumen 

 linear, obtuse, up to 6 lin. long), 3J-5J in. long, 1 J-lf in. broad, cori- 

 aceous, fuscous when dry; midrib slightly sunk above, raised below; 

 secondary nerves about 4-6 to an inch, fine, very faintly raised on both 

 sides ; veins quite obscure ; marginal arches close to the margin without 

 an outer marginal nerve ; margin revolute ; petiole 4 lin. long. Cymes 

 ^exclusive of the corollas) as long as the petioles or slightly longer, 

 5- to many-flowered, minutely and scantily pubescent ; bracts minute ; 

 pedicels up to 2 lin. long, slender. Calyx slightly over J lin. long, 

 glabrous ; sepals ovate, subacute or obtuse, ciliolate. Corolla white, 

 glabrous except the ciliolate lobes ; tube about 3 J lin. long, subcylindric, 

 slender, slightly widened just above the calyx ; lobes linear, subacute, 

 3-3 J lin. long. Stamens inserted near the base ; filaments very short ; 

 anthers oblong, subobtuse. Ovary turbinate-globose, truncate, top 

 pubescent ; style distinct, cylindric, very short ; stigma clavate, slightly 

 longer than the style. — G. viscijlua, Hallier f. Kautschuklianen in Jahrb.

Upper Guinea. Cameroons: Johann Albrecht's Hohe, in forest, Staudt, 

 860! 



This is, no doubt, nearly allied to C. viscijlua, but distinguished by the narrower, 

 more coriaceous, more obscurely nerved leaves, the laxer, slightly puberulous inflores- 

 cences and the hairy ovary-top. 



10. C. cirrhosa, Radlk. i7i Ahhandl. N'aturw. Ver. Bremen, viii. 

 (1883) 400. A climbing shrub with slender hook-branched tendrils ; 

 young branches dark reddish-brown, almost glossy, with minute 

 lenticels. Leaves elliptic, abruptly acuminate (acumen linear, obtuse, 

 up to \ in. long), rounded at the base, 2J-3| in. long, lJ-1 J in. broad, 

 thinly coriaceous, almost opaque ; margins slightly wavy ; midrib flat 

 or slightly convex above, slightly raised below ; secondary nerves about 

 15 to an inch, fine, faintly raised on both sides with still finer, parallel 

 tertiary ones between them; petiole 2-4 lin. long. Cymes many-
