The type also occurs in South Africa, and is probably not separable from the 
Tropical Asiatic and Australian M. hastata, Hallier f. (= Ipomea denticulata 
R. Br.). 
23. M. pinnata, Hallier f. in Engl. Jahrb. xvi. 552 and xviii. 116. 
Annual. Stems slender, trailing or twining, pubescent with soft 
spreading hairs. Leaves sessile, more or less hairy like the stem, 
resembling those of Quamoclit vulgaris, pinnate, about 1 in. long, with 
8-10 pairs of entire linear segments spaced out on the rhachis. Peduncles 
short, about as long as, or longer than the leaf, 1—3-flowered ; pedicels 
very short; bracts linear, resembling the leaf-segments. Calyx covered 
with the characteristic hairs, about 2 lin. long; sepals subcoriaceous, 
elliptic, with the apex drawn out into a long point, the two inner much 
smaller. Corolla narrowly funnel-shaped, yellow, scarcely exceeding 
the calyx. Anthers ultimately slightly twisted. Ovary denscly hairy, 
4-celled, 2 ovules in each cell. Capsule small, globose, hairy, 3 lin. in 
diam. Seeds glabrous.—Hallier f.in Engl. Jahrb. xxx. 386; Dammer in

24. M. emarginata, Hallier f. in Engl. Jahrb. xviii. 118. Peren- 
nial, with a long woody root. Stems slender, trailing, glabrous or 
slightly pubescent. Leaves orbicular- or ovate-reniform, 3-1 in. broad, 
very obtuse, with a broad rounded basal sinus, rarely obscurely 
3-lobed ; petiole a little shorter or as long as the blade. Flowers 1-2, 
nearly sessile in the axils of the leaves; buds shortly ellipsoid, blunt. 
Calyx 2 lin. long; two outer sepals shorter and smaller than the 
inner, obovately-elliptic, subacute, glabrous; 3 inner obovate, obcor- 
date, obsoletely cuspidate, upper half with long ciliate margin, Corolla 
tubular-campanulate, scarcely exceeding the calyx, yellow with a dark 
eye; midpetaline areas well defined. Capsule globose, glabrous, milky,
