Corolla 5-lobed, white to light red, usually glabrous; lobes linear-lanceolate, much shorter than tube; tube narrowly cylindric, sometimes bearded in throat. Stamens (4)5, arising in throat of corolla, exserted; filaments slender; anthers oblong, dorsifixed. Ovary 2-locular, with a single erect ovule in each locule, attached near base; style filiform, bilobed, exserted; stigmas smooth, filiform.
