subscarious, with prominent nervation, \ in. long-. Flowers in terminal 

 somewhat intricate puberulous paniculate racemes and from the upper 

 axils, usually shorter than the leaves. Bracts ovate ^ in. or less ; 

 bracteoles minute, ovate, acute. Pedicels straight, from the last pedicels 

 \ in. more or less. Calyx-tube slender, f in. long, puberulous ; lobes 

 elliptic-oblong. Petals obovate-oblong, exceeding the calyx, caducous. 

 Base of staminal sheath continued around the faux as a prominent

5. G. Barteri, Rook. f. mss. Climbing shrub, about 7 ft. high, 

 with greenish-white flowers {Barter) • extremities slender glabrous. 

 Leaves elliptical apiculate or shortly acuminate, rounded or broadly 

 cuneate at base, glabrous and shining on both sides, principal lateral 

 nerves 4-6 on each side, distant, not prominent; 2J-5 in. long, 1^-2 

 in. broad more or less, petiole eglandular J-J in. Stipules narrow- 

 linear. Inflorescence as in G. Mannii, puberulous. Bracts and pedicels 

 the same. Calyx-tube very slender, J-| in. long, outer lobes elliptical 

 acute, inner obtuse. Petals about equalling the calyx, elliptic-oblong.

 crustaceous ; seed thinly covered with straight appressed rigid hairs. 



Upper Guinea. Lagos, Barter! Old Calabar, W. C. Thomson! 

 Allied to G. Mannii, but smaller in nearly all its parts. The stipules appear diag- 

 nostic.

Flowers occasionally polygamous. Calyx turbinate or campanulate, 

 toothed, deciduous leaving a narrow ring. Petals 5 (10-12) or 0, 

 inserted in mouth of calyx, small. Stamens 10-20, perigynous. Ovary 

 sessile, narrowed into the style ; ovules geminate, laterally affixed (or 

 pendulous), collateral ; stigma terminal. Fruit dry, crustaceous, sub- 

 globose or transversely ellipsoidal, 1-seeded (in P. africanum).— -Trees 

 or shrubs, glabrous (or tomentose). Leaves alternate, simple, petiolate,

A small genus of the warmer parts of the Old World. Tbe following appears to be 

 endemic.
