 late, 1-1 f in. long, ^-J in. wide, scarcely acute, 3-nerved, entire or 

 furnished with a few small teeth, longer than the internodes. Flowers

 filiform ; bracteoles much longer than the flowers. Calyx thin, cam- 

 panulate, J-J in. long, 10-ribbed, nearly equally 5-lobecl, setulose on the 

 ribs and margin ; lobes deltoid, acuminate, acute, as long as the tube. 

 Corolla about -J in. long, longitudinally lo-nerved, not net-veined. 

 Stamens nearly equal ; longer filaments strongly bearded ; anther-cells 

 nearly equal, obtuse. — Melasma indicum, Hiern in Cat. Afr. PI. Welw. i.

 degrees. Leaves rather thick and rigid, lower stalked, opposite, upper

 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. — Melasma pictimi, Hiern in Cat. Afr. PL Welw. L
