Flowers bisexual, zygomorphic, usually large. Calyx campanulate or tubular, truncate, 2-5-dentate, or glandular subulate-dentate. Corolla campanulate or funnelform, usually bilabiate; lobes 5, imbricate or valvate. Fertile stamens 4 (didynamous) and staminode 1, or 2 and staminodes 3, rarely all 5 stamens fertile. Disc fleshy. Ovary superior, 2-locular, rarely 1- or 4-locular; placentation axile or parietal; ovules numerous. Style filiform; stigma 2-lobed.
