Draba cuneifolia

Draba cuneifolia is a species of flowering plant in the family Brassicaceae known as the wedgeleaf draba or wedgeleaf whitlow-grass. This annual plant is native to the southern half of North America where it grows in open, rocky fields and other disturbed areas. The plant forms a basal cluster of leaves, which are thick, widely toothed, and coated in stiff hairs. It bolts one or more erect stems which may approach 40 centimeters in maximum height. Each hairy stem bears an inflorescence of up to 75 small white flowers that continue at intervals down the stem as the stem grows in height. This family and its plants are easy to identify with its 4 petals and 4 sepals arranged like a "cross", either in an "X" or "H" shape, thus the name "Cruciferae". Mustards have 6 stamens usually 4 are taller and 2 are shorter. Fruits are either a long thin silique or short often rounded silicle.[1]
