Coast Recion: Port Elizabeth Div. ; near Port Elizabeth, 250 ft., West in 
MacOwan, Herb, Austr.-Afr., 1924 ! 
Closely allied to C. natalitium, but evidently a smaller and much more slender 
plant, with less fleshy leaves. It is possibly a hybrid between C’. africanum and 
C. natalitium, but does not quite agree with either species. 
7. C, africanum (R. Br. Prodr. 463); plant branching from the 
base into several twining stems, thinly or densely covered with a_ 
soft spreading pubescence ; leaves thinly coriaceous or rather thick 
and probably somewhat fleshy, more or less pubescent on both sides 
or glabrous ; petiole 1-3 lin. long; blade 1—1 in. long, 4—} in. 
broad, suborbicular, ovate, elliptic-oblong or oblong, acute or obtuse, 
apiculate, rounded to subcordate at the base ; umbels lateral at the 
nodes, 5—7-flowered ; peduncles }—11 in. long, pubescent to nearly 
glabrous ; bracts about 1 lin. long, ovate or deltoid-ovate, acute ; 
pedicels 1-5 lin. long, pubescent ; sepals 1-1} lin. long, 3—} lin. 
broad, ovate, acute, pubescent to nearly glabrous; corolla-tube 
5—? lin. long ; lobes 3-4 lin. long, 1 lin. broad, oblong-linear, obtuse, 
recurving or twisted and suberect, glabrous on both sides or slightly 
pubescent on the back, dark purple-brown ; corona 24—4$ lin. long, 
tubular, usually irregularly about 10-toothed, but sometimes with 
5 entire or bifid teeth 4-1 lin. long at the top, glabrous, white ; 
staminal column 21-34 lin. long, terete, suddenly contracted under 
the anthers into a slender stipe 13—2# lin. long ; anther-appendages 
lanceolate, acute, connivent over the shortly conical minutely 
2-lobed style-apex ; follicles about 24 in. long and 4~44 lin. thick, 
narrowly lanceolate, tapering into a long slender acute beak,
