Flowers:
Racemes somewhat headlike in flower, greatly elongated in fruit; flower stalks erect or closely ascending, 2-6 mm long, hairy; petals white or purplish, 3-4 mm long; sepals 1.5-2.5 mm long, hairy, deciduous;

An adequate monograph of North American Braya (especially those of the far north) has yet to be done, thus our taxonomy of these species is often confusing.
