cordate at the base, sometimes with a shallow open sinus, sometimes 
with a narrow and deeper sinus, 5-nerved. Umbels or umbel-like 
racemes sometimes sessile and pedunculate on the same stem, 10-20- 
flowered ; peduncles 14-3 lin. long; pedicels 2-3 lin. long, slender. 
Sepals } lin. long, ovate-oblong, obtuse, minutely ciliolate. Corolla 
white, 5-iobed nearly to the base, probably rotate; lobes 14 lin. long, 
lanceolate, acute. Corona-tube 3-1 lin. long, 10-toothed, with 5 of the 
teeth longer than the rest and channelled down the face, 4-4 lin. 
long, acute or denticulate at the apex, the shorter teeth more or Jess 
recurving, or with all the teeth subequal. Staminal-column variable ; 
anther-appendages long, erect, narrowly lanceolate, sometimes reaching 
to the tips of the coronal teeth, sometimes much shorter than them 
and connivent around the shorter terete or conical-terete or bifid apical 
part of the style.—Vincetowicum Adaline, K. Schum. in Engl. Jahrb.

This plant seems to. be very variable in the toothing of the corona and in the 
relative height which the staminal-column attains. 
7. C. fraternum, JV. H. Br. in Kew Bulletin, 1895, 256. Stem 
slender, twining, pubescent on the young parts, becoming glabrous. 
Leaves herbaceous, thin; petiole 2-6 lin. long; blade 3-2 in. long, 
4-1 in, broad, oblong-ovate, acuminate, broadly rounded, subtruncate 
or cordate at the base, with a few minute scattered hairs above, gia- 
brous beneath. Racemes or corymbs short, somewhat umbel-like, lateral at 
the nodes, many-flowered ; peduncle 1-4 lin. long, puberulous; pedicels 
13-4 lin. long, puberulous. Sepals } lin. long, broadly ovate, subacute, 
Sparsely pubescent. Corolla rotate, 24 lin, in diam. ; lobes about 1 lin.

tubular part rather more than } lin. long. Staminal-column shorter 
than the coronal-tube ; anther-appendages suborbicular or subquadrate,. 
more or less toothed at the subtruncate apex, closely inflexed over the 
truncate apex of the style, which is not produced beyond them.

Nearly allied to C. altiscandens, K. Schum., and C. schistoglossum, Schlechter ; 
from the former it may be at once distinguished by the long subulate coronal-teeth 
and broad anther-appendages ; from the latter by the larger flowers and much 
longer corona. :
