Flowers - Perianth tubular, the sepals and petals 3-5 mm long, narrowly ovate-triangular, pointed, purplish pink to white or greenish white.
Fruits - Capsules 3-5 mm long, narrowly ovoid, trigonous to somewhat 3-lobed, the angles or lobes with a thickened ridge.

Other info. - This weedy species can be found throughout most of Missouri, and is probably undercollected and more common than the dot map suggests. The plant is a pest in agricultural fields. It will impart an oniony flavor to the milk of cows which graze upon it, and the bulblets can contaminate grain harvests.
