column, 14 lin.long,somewhat compressed, adnate in the lower half, which 
is deeply grooved on the back, with slightly spreading wing-like sides ; 
apical half free, linear-oblong, obtuse or acute, slightly concave on the 
inner face, incurved over the backs of the anthers and apex of the style. 
Anther-appendages } lin. long, deltoid or ovate, acute, free, connivent 
around the stout subhemispherical apex of the style, which does not 
exceed them in length.—Hiern in Cat. Afr. Pl. Welw. i. 692.

10. M. leonensis, Benth. in Hook. Niger Fl. 455. Stem twining, 
minutely puberulous, slender. Leaves spreading or deflexed ; petiole 
1-1} in. long; blade 3-4 in. long, 14-1? in. broad, cordate-oblong, 
abruptly acuminate into an acute point 4-4 in. long, glabrous on both 
sides. Cymes subaxillary, 3in. long, pedunculate, two-branched, puber- 
ulous; branches }-4 in. long, bearing several flowers racemosely 
arranged ; bracts minute; pedicels 14-2 lin. long, puberulous. Sepals 
barely 1 lin. long, elliptic or orbicular, very obtuse, puberulous. Corolla 
glabrous outside; tube } lin. long, broadly campanulate, with long 
retrorse white hairs within, and 5 tufts of similar hairs on minute tuber- 
cles at the sinuses of the corolla-lobes, which are as long as the tube, 
ovate, subacute. Coronal-lobes arising at the base of and a little shorter 
than the ? lin. long staminal-column, adnate at their basal half to the 
column and dorsally produced into dark-coloured ascending tooth-like 
tubercles, which are grooved behind, distinctly confluent at their base 
and reach up between the pairs of anther-wings to their middle or a 
little beyond; their apical half free, subulate, acute, white, erect, 
applied to the backs of the anthers. Staminal-column with the filament 
part undeveloped, and the anther-wings extending nearly to its base; 
anther-appendages ovate-oblong, obtuse, longer than broad, incumbent 
on the short conical style-apex, which they cover.—Walp. Ann. iii. 61.

lin. long, puberulous. Sepals 4-2 lin. long, elliptic or orbicular-ovate, 
obtuse, sparsely puberulous, ciliolate. Corolla 1-1} lin. long, glabrous

lobes as long as the tube, deltoid-ovate, acute. Corolla-lobes not quite 
reaching to the tops of the 2 lin. long staminal-column ; basal part 
adnate, fleshy, grooved behind ; apical half free, ovate-lanceolate, acute, 
applied to the backs of the anthers. Anther-appendages short, some.
