23. Guerkea schumanniana, De Wild. & Durand in Comptes- 
vendus Soc. Bot. Belg. xxxviii. 128. A climbing shrub; branches 
slender, terete, velvety, compressed when young. Leaves oblong or 
obovate, shortly acuminate, obtuse or subcordate at the base, 1-1? in. 
long, 3-1 in. broad, sparingly hairy above, long hairy on the nerves 
below ; secondary nerves about 5 on each side, slightly raised on both 
surfaces. Panicles few-flowered, shorter than the leaves, minutely 
tomentose; peduncle 5 lin. long. Calyx ? lin. long; sepals oblong- 
ovate. Corolla subcampanulate, minutely tomentose without; tube 
1} lin. long ; lobes as long as the tube. Ovary hairy. Follicles elongate,

long ; coma 11 lin, long. 
South Central. Congo Free State: Bangala, Dewévre (flowers) ; Bumba, on 
the River Congo, Dewevre (fruits). 
The deseription answers very well to the genus Baissea, and Hua (in Compt. 
Rend. Acad. Paris, exxxiy. 857) points out that G. schumanniana is actually 
identical with B. axillaris, Stapf.

Calyx small, herbaceous, with 3-5 very minute intracalycular glands, 
rarely eglandular ; sepals 5, free or nearly so, slightly imbricate, ovate,

mouth, with or without minute callous scales some way above the in- 
sertion of the stamens and with dense obversely triangular patches of 
White reflexed hairs between them; lobes short, ovate, overlapping to 
the right. Stamens inserted below the middle of the corolla-tube ; 
filaments extremely short, stout ; anthers conniving in a cone, included, 
lanceolate, acute, sagittate; appendages as long as or longer than the
