The author does not state if the corolla-lobes are free or connate, but as he at 
first named the plant C. Woodii, they are probably connate at the tips, as in that 
species. 
26. C. tenuis (N. E. Br.) ; stems long, twining, very slender, }~} 
lin. thick when dried, glabrous ; leaves apparently somewhat fleshy, 
glabrous ; petiole 14-3 lin. long; blade 4-1 in. long, 4-3 in. broad 
near the base, ovate or deltoid-ovate, acute or obtuse and apiculate ; 
cymes pedunculate, subumbellately 3—6-flowered ; flowers successively 
developed ; peduncles 14-4 lin. long, glabrous ; pedicels 13-2 lin. 
long, glabrous ; sepals 1-1} lin. long, lanceolate, acute, glabrous ; 
corolla-tube 3—3 in. long, ovoid-inflated and probably about 2 lin, in 
diam. at the base, cylindric and 3 lin. in diam. above, gradually 
widening to 1} lin. across the mouth, glabrous outside, thinly pilose 
with fine hairs within above the inflated part, which is smooth 
within, apparently whitish or pale greenish, passing into blackish- 
purple at the mouth; lobes 2 lin. long, erect, connate at the tips, 
linear-spathulate from a deltoid 3 lin.-broad base, replicate, glabrous, 
ciliate with long purple hairs along the keel on the inner face 
formed by the folding, blackish-purple ; outer corona scarcely } lin. 
long, arising above the base of the staminal column, cupular, with 
entire subtruncate margins to the pocket-like spaces, glabrous, rising 
into 5 short deltoid obtuse lobules behind and adnate to the inner 
corona-lobes, which are 1 lin. long, dorsally flattened, lanceolate- 
spathulate, acute, connivent-erect, much overtopping the 3 lin.-long 
staminal column, white. 
Eastern Recron: Transkei; forests near the coast of Kentani Div., near sea-

pubescent ; blade }~1} in. long, 4-? in. broad, or perhaps larger, 
ovate, very acute or obtuse and apiculate, cordate or rounded at the 
base, remarkably lobulate-undulate on the margins, pubescent on 
both sides; cymes pedunculate, umbel-like, 6—18-flowered, the 
flowers developing successively ; peduncles }—1 in. long, pubescent ; 
pedicels 14-3 lin. long, pubescent ; sepals 14—1} lin. long, subulate, 
pubescent ; corolla-tube curved, about } in. long, ovoid-inflated and 
about 1} lin. in diam. at the base, cylindric and } lin. in diam. 
above, gradually widening to 14-1? lin. in diam. at the mouth, 
puberulous outside, glabrous within ; lobes erect, connate at the 
tips, 5-6 lin. long, ? lin. broad at the base, linear-spathulate, 
puberulous on the back, glabrous on the flat keelless inner face ; 
outer corona not rising above the staminal column, cupular, probably 
obtusely pentagonal, rising into 5 minute erect teeth behind the
