2n=32 (Moss, 1983). Also known as Lepidium densiflorum var. densiflorum and Lepidium densiflorum var. macrocarpu (this species has larger fruits at 3-3.5 mm long) (Moss, 1983). Pepper-grasses have been eaten; they have been added to salads, sandwiches and hors-d'oeuvres to add zest (Johnson et al., 1995). It has been added to soups, sauces and casseroles; pods and seeds have a stronger taste; seeds can be dried for later use; good source vitamins and minerals; vitamin C levels used to prevent scurvy (Johnson et al., 1995).
