1817. Viola ovata Nutt. Gen. 1: 148. 1818. V. sagittata var. ovata T. & G. Fl. N. A. 1: 133. 1838.

Rootstock becoming long and stout, usually erect; the blades of the earliest leaves ovate, obtuse, those of the later oblong-ovate, acute or somewhat obtuse, finely pubescent especially beneath, obscurely crenulate toward the apex, the lobes of the subcordate or truncate base often sharply toothed, incised, or auriculate; scapes usually much exceeding the leaves; sepals lanceolate, acuminate, with auricles somewhat spreading and ciliate; corolla violet-purple; capsules green, ovoid, 3"-5" long; seeds brown; cleistogamous flowers on erect peduncles.

Dry fields and hillsides. Nova Scotia to Wisconsin, south to the mountains of northern Georgia. Viola conjugens Greene is apparently a hybrid between this species and V. sagittata. April-May. Fringed or rattle-snake violet.

Viola sagittata Ait. Hort. Kew. 3: 287. 1789.

Usually glabrous, but the leaves often ciliate or finely pubescent throughout; petioles commonly longer than the blades; these lanceolate or oblong-lanceolate, becoming 1 1/2'-4' long, cordate to truncate, obtuse or acute, distantly and obscurely toothed above the middle, hastately or sagittately toothed or cleft at the base; the earliest leaves and those produced in late summer often deltoid-ovate, obtuse, merely crenate at the base; flowers on peduncles as long as the leaves, or somewhat longer; corolla violet-purple; sepals narrowly lanceolate, acute, glabrous; capsules 4"-7" long, containing 50-70 brown seeds.
