Key pattern

Opposite or alternate leaves on herbs; regular flowers typically show four petals above an inferior ovary topped by a distinctive X- or cross-shaped stigma, opening in the evening in several genera and ripening into a capsule.

Several species open their flowers only at dusk, releasing a strong fragrance to attract night-flying moth pollinators — the trait behind the common name evening primrose.
