Inflorescence racemose, bracteate, flowers 8-26; fruiting pedicels 10-35 mm, hairy as stems; calyx straight-erect or nodding at 45-100 degrees, ovate to bell-shaped, inflated, compressed along sagittal plane, 15-22 mm, hairy as stems, throat closing; corollas yellow with red spots inside, symmetric bilaterally, bilabiate; tube-throat widely funnel-shaped, 16-24 mm, protruding 10-15 mm beyond calyx margin, limb widely expanded; styles hirtellous; anthers not protruding, glabrous.
