Lower and basal leaves spatulate-oblong, obtuse; upper leaves oblong, 6'-i2' long, 3'-s' wide, acute or obtuse; bracts scarious-margined; inflorescence cymose, loose, the pedicels at length much longer than the calyx; sepals obtuse or acute, about equalling the 2-cleft petals, 2'-3' long; capsule curved upward. In fields and woods, nearly throughout our area. Naturalized from Europe. Often 3 troublesome weed. Occcurs also in the Southern and Western States, and is native in northern Asia. Mouse-ear.
