Flowers often showy, mediocre or large, purple, pink, lilac or yellow, rarely whitish; pedicel short or long in fruit, ± ascending, often slightly thickened above. Sepals erect, inner saccate at base. Petals about twice as long as the sepals, spathulate-oblong, clawed, apex ± emarginate. Stamen 6; filaments not appendaged; anthers oblong, obtuse. Lateral nectar glands usually in pairs, pyramidate or semi-annular; middle glands absent. Ovary linear, usually with irregular margins, bilocular, 8-26-ovuled; style long with short, bilobed stigma.
