Flowers plesiogamous, 4–10(–12), on foreshortened distal nodes, usually clustered, chasmogamous, sometimes cleistogamous. Fruiting pedicels 6–14 mm, glabrous. Fruiting calyces urceolate to urceolate-campanulate, inflated, sagittally compressed, 8–11 mm, glabrous, throat closing. Corollas yellow, proximal lip sometimes red-splotched, palate ridges yellow, bilaterally symmetric, bilabiate; tube-throat cylindric-funnelform, 4–8 mm, exserted 0–2 mm beyond calyx margin or not; palate ridges densely villous.
