Flowers herkogamous, 1–9, from medial to distal nodes. Fruiting pedicels divergent-arcuate, 12–38 mm, minutely stipitate-glandular, hairs 0.1–0.3 mm, gland-tipped. Fruiting calyces cylindric, ± inflated, 7–10 mm, margins distinctly toothed or lobed, minutely stipitate-glandular, hairs 0.1–0.3 mm, gland-tipped, lobes pronounced, erect. Corollas yellowish, tube-throat, palate ridges, and limb yellow to pale yellow, abaxial limb red-dotted or not, bilaterally symmetric, weakly bilabiate; tube-throat funnelform, 6–9 mm, exserted beyond calyx margin; lobes broadly obovate-suborbicular, apex rounded. Styles glabrous. Anthers included, glabrous. Capsules included, 5–8 mm. 2n = 32.


Phenology: Flowering Apr–Jul.
