long, IJ lin. broad. Ovary rufo-pubescent ; style 3J-4J lin. long, rough 

 with minute curved hairs. Fruit globose, very large, orange-coloured 

 (Dinklage).

 in forest, climbing into the highest trees, Zenker, 1573 ! 



Hallier also referred two specimens collected in the Cameroons by Dinklage 

 (1060 ! 1457 !), to C. maxima, from which both are certainly distinct, but the material 

 is too incomplete for description. No. 1060 has very large elliptic leaves (12 in. 

 by 7 in.) with a broad, abruptly subacute base and very fine indumentum, and 

 numerous dots below. No. 1457 has similar, but narrower and perfectly glabrou? 

 leaves. 



2. C. uniflora, Stapf in Kew Bulletin, 1894, 19. A climbing 

 shrub with pseudo-axillary tendrils ; branches finely rusty- hairy when 

 young, soon quite glabrous except the flowers, pale brown ; lenticels 

 few. Leaves oblong-lanceolate, abruptly and obtusely acuminate; 

 cuneate at the base, 6-9 in. long, 2 in. broad, pale green on both sides 

 or almost glaucous above (dark green when fresh according to Dink- 

 lage) ; midrib narrowly channelled above ; secondary nerves 6-8 on 

 each side, finely channelled above, prominent below, connected by bold 

 arches rather distant from the margin ; petiole stout, 4-6 lin. long. 

 Flowers axillary, solitary, subsessile ; bracts 4, broad, ovate, obtuse, 

 finely pubescent. Calyx IJ lin. long; sepals similar to the bracts. 

 Corolla violet ; tube rather wide, 6|^-7 lin. long, widened below the 

 mouth, finely pubescent without, slightly pubescent within ; lobes 

 linear-lanceolate or linear, as long as the tube. Ovary and style- base 

 shortly fulvo-tomentose ; style stouter than in the other species. Fruit 

 citron-yellow {Dinklage). — Oliver in Hook. Ic. PI. t. 2340; Jumelle, PI.

Ziower Guinea. Gaboon : Munda ; Sibange Farm, Soyaux, 269 ! and without 

 precise locality, Klaine, 910 ! 



Soynux states that this species yields a very fine rubber. Dinklage, 1270 ! from 

 Batanga, quoted by Hallier, I.e. under C. unijiora, is evidently some other species, 

 perhaps C. parvijlora ; but the specimen is too defective for determination. 



3. C. Schlechteri, K. Schum. in Schlechter, Westafr. Kautschuk- 

 Exped. 306 {name only), 305 with fig. A tall, glabrous climber, with 

 flagelliform tendrils from the branch- forks. Leaves lanceolate or 

 oblong-lanceolate, gradually acuminate, obtuse or subacute at the ba^e, 

 3-4 in. long, 1-1 J in. broad, coriaceous, glabrous ; midrib channelled 

 above, raised below ; secondary nerves about 6 on each side, connected 

 by bold arches (rather remote from the margin), finely channelled 

 above, raised below; reticulation conspicuous, raised on both sides; 

 petiole up to 3 lin. long. Flowers axillary, solitary, subsessile. Calyx 

 1| lin. long; sepals 4, ovate, subacute, membranous, ciliolate, otherwise 

 glabrous. Corolla 1 in. long in bud ; tube slightly widened below the
