(Boechera pusilla)
Small rockcress is a perennial herb with 2-several decumbent stems up to 17 cm long. The basal leaves are linear and erect with relatively sparse simple, biforked, or triforked spreading hairs. The 3-5 stem leaves are sessile, non-clasping and widely spaced. Flowers are light-lavender, 4-petaled, and 3.5-4.5 mm long. The fruits are glabrous, linear siliques (1-3.8 cm long and 2 mm wide) that spread at right angles from the drooping main stem on pedicels 3 mm or shorter (Rollins 1982; Fertig et al. 1994, AlShehbaz and Windham 2010)
