3. T’. cameroonica, V. /. Br. in Kew Bulletin, 1895, 258. A 
vigorous climber, with a hollow glabrous stem. Leaves apparently 
slightly fleshy ; petiole #-1} in. long; blade 3-5} in. long, 2-3 in. broad, 
ovate to elliptic-ovate, rather abruptly cuspidate-acuminate, cordate, 
with a shallow broadly open sinus at the base, glabrous; only the 
primary veins visible on the underside. Flowers in small clusters or 
very short racemes scattered along the branches of lateral subsessile 
or shortly pedunculate lax cymes, which have 3 primary branches that 
are again once or twice trichotomously or dichotomously divided, the 
whole cyme having a spread of 4—5 in. with a height of 2-3 in., at first 
minutely rusty-puberulous, becoming glabrous; pedicels 1$—2 lin. 
long, puberulous. Sepals }—3 lin. long, lanceolate, acute, glabrous. 
Corolla rotate, 24 lin. in diam. ; lobes 1 lin. long, 3 in. broad, ovate, sub- 
obtuse, ciliolate along one margin. Coronal-tubercles fleshy, transversely- 
oblong, radiating from the base of the } lin. long staminal-column, 
with their upper face sloping nearly up to the base of the anthers, dark 
coloured in the dried state.

twining, slender, perfectly glabrous. Leaves on rather long petioles, 
ovate, broadly elliptic, or suborbiculate, acute or often obtuse or retuse, 
apiculate, cordate at the base, membranous, dark green, glabrous.

green, glabrous. Corolla rotate, 2 lin. in diam., glabrous; lobes 
% lin. long, elliptic-oblong, obtuse. Coronal-tubercles minute, arising 
a little above the base of the 4 lin. long staminal-column.

twining, slender, with two puberulous lines. Leaves spreading ; petiole 
3-2 in. long; blade 14-6 in. long, 1-3} in. broad, oblong, ovate- or 
elliptic-cordate, acuminate, acute, or shortly and abruptly apiculate- 
cuspidate, glabrous, slightly pubescent along the midrib and nerves 
above and down the face of the petiole. Inflorescence sublateral at the 
nodes, 4-6 in. long, pedunculate, simple or branched, minutely 
pubescent, bearing several sessile clusters of small brownish-purple 
flowers racemosely scattered along it, }—} in. distant; pedicels 2-3 
lin. long, pubescent. Sepals 4-4 lin. long, ovate, acute or subobtuse, 
puberulous. Corolla rotate, purplish, 14-2 lin. in diam., 5-lobed nearly 
to the base; lobes 3—1 lin. long, oblong, obtuse or subacute, glabrous. 
Coronal-tubercles transverse, arising near the base of the barely } lin. 
long staminal-column, dark coloured in the dried state. Follicles 
23-31 in. long, lanceolate, acuminate, smooth and glabrous. Seeds
