late, 1-i? in. long, }-} in. wide, scarcely acute, 3-nerved, entire or 
furnished with a few small teeth, longer than the internodes. Flowers 
“‘ yellow ;” floral-leaves or bracts shorter than the calyx, linear or almost 
filiform ; bracteoles much longer than the flowers. Calyx thin, cam- 
panulate, 1-4 in. long, 10-ribbed, nearly equally 5-lobed, setulose on the 
ribs and margin; lobes deltoid, acuminate, acute, as long as the tube. 
Corolla about 4 in. long, longitudinally 15-nerved, not net-veined, 
Stamens nearly equal; longer filaments strongly bearded ; anther-cells 
nearly equal, obtuse.— Melasma indicum, Hiern in Cat. Afr. Pl. Welw. i.

degrees. Leaves rather thick and rigid, lower stalked, opposite, upper 
alternate, elliptic to linear, 3-1} in. long, obtuse or rotundate, often 
with a few obscure teeth. Flowers solitary in the axils of the alternate 
leafy bracts, which are gradually smaller upwards. Pedicels shorter 
than the calyx. Bracteoles linear. Calyx hispid, campanulate, about 
4 in, in diam., equally 5-lobed ; lobes triangular, obtuse, equalling the 
tube, costate or almost keeled, elegantly veined. Corolla yellow with 
red lines; tube very short, contracted at the top and then expanded 
into a campanulate, almost equally 5-lobed limb; lobes rounded. 
Stamens nearly equalling the corolla; filaments bearded above the 
middle; anther-cells large, unequal, obtuse, the larger one embracing 
the smaller in a half spiral; connective of the longer stamens produced 
above the cells.—Jelasma pictwm, Hiern in Cat. Afr. Pl. Welw. 1.
