This species appears from the description to be very similar to C. abyssinica, of 
wh‘ch it may be only a form, with larger leaves and a hairy corona,

Peduncles lateral at the nodes, 1-3 lin. long, 1—2-flowered, slender, 
glabrous; pedicels 14-3 lin. long, glabrous. Sepals 1-1} lin. long,

slightly and gradually inflated in the lower part, slightly dilated at the 
mouth, glabrous outside; lobes 21 lin. long, connivent-erect, cohering 
at the tips, linear from a deltoid base, ciliate —C. vignaldiana, Vatke

I describe this plant from the figure and the few diagnostic characters given by 
Schumenn in the work above quoted; it is very distinct from C. vignaldiana, A. 
Rich., the leaves being very much narrower, and the corolla small and altogether 
different in form. 
Lmperfectly known species. 
51. C. aristolochioides, Decne. in Ann. Sc. Nat. 2 sér. ix. 263. 
Glabrous. Stem twining, fleshy. Leaves fleshy, petiolate, 2-3} 
in. long, 14-2} in. broad, cordate, shortly acuminate, very acute. 
Peduncles spreading, sometimes longer than the leaves, few-flowered ; 
flowers pedicellate, purple-brown. Sepals  subulate, acuminate. 
Corolla-tube curved, inflated at the base; lobes lanceolate (rounded in 
another description), cohering into a hemispherical limb, apiculate. 
Outer coronal-lobes bifid, pilose with long hairs; inner coronal-lobes 
ligulate, glabrous.—Decne. in DC. Prod. viii. 642; Vatke in Oest. Bot.

I have not seen this plant, and quote the specimens from Eritrea and Abyss-nia 
en the authority of Vatke & Engler. Dr. Schumann in Engler, Ff. Ost-Afr. C. 
327 records it from German East Africa, but I have not seen any specimens from 
that region.
