Flowers ca. 8 mm long, the sepals free, the outer 3 sepals ovate, 7 mm long, 2-3 mm wide, larger in fruit, apically acute, basally obtuse or rounded, mostly lacking glands, inner 2 sepals linear, slightly shorter than the outer sepals; corolla tubular, exserted, yellow with purple lines, ca. 8 mm long, 5-lobed, the lobes recurved, rounded, sometimes irregularly crenulate, or emarginate, alike but the posterior pair with a short sinus, bearded in the throat; stamens 4, a rudimentary staminode sometimes present, the filaments glabrous, inserted at unequal heights in the lower 1/2 of the tube, free ca. 2 mm, the anther 2-thecate, the thecae oblong, held apart on expanded connectives, the connectives consisting of a discoid or ellip-soidal expansion at the filament apex and one slender arm to each theca; ovary narrowly ovoid, longitudinally sulcate, the styles 1.5 mm long, connate, apically flattened, the stigma a linear crest on the slightly curved, flattened styles. Capsule narrowly ovoid, ca. 4 mm long, the walls stramineous, dehiscent loculicidally and septicidally from the apex; calyx accrescent, the outer sepals becoming 9 mm long and 5 mm wide; enlarged, linear placenta persistent on the withered capsule; seeds numerous, ovoid, 0.3 mm long, longitudinally ridged with a reddish brown reticulum.
