10. C. hastifolium, JV. Z£. Br. in Kew Bulletin, 1895, 257. Stems 
twining, slender, woody below, pubescent on the very young shoots and 
in the leaf-axils, becoming glabrous. Leaves spreading ; petiole 3-6 
lin. long; blade 4-14 in. long, 14-3 lin. broad at the middle, 3-7 lin. 
broad across the basal lobes, hastate; front lobe linear-oblong, acute ; 
basal lobes oblong or deltoid, very obtuse, broadly cuneate or truncate 
at the very base, both sides glabrous. Umbels sessile between the 
bases of the petioles on the young shoots, few-flowered; pedicels 2—3 
lin. long, puberulous. Sepals 1 lin. long, subulate, puberulous. Corolla 
d-lobed almost to the base; lobes 24—3 lin. long, }-? Jin. broad, linear, 
acute, glabrous, margins strongly revolute. Corona arising at the buse 
of the staminal-column, with a plicate tube 1? lin. long, and 10 teeth 
% lin. long, alternating with 10 minute teeth, 5 of the teeth deltoid, 
obtuse or subacute, the other 5 filiform, slightly clavate, with 5 pairs of 
keels decurrent from them within the tube, opposite the anthers. 
Staminal-column reaching to the top of the coronal-tube, shortly stipi- 
tate within the corona; anther-appendages erect, very large, orbicular 
or orbicular-quadrate, subtruncate or apiculate. Apical part of the style 
about as long as the anther-appendages, shorter than the corona, of 
equal thickness throughout.—C. hastifolium, K.Schum. in Engl. &
