Caudex usually simple. Stems usually few from base, erect or outer decumbent, 1.5–2.5 dm. Basal leaves: blade (outer) often broadly elliptic, base narrowing gradually to petiole, margins sinuate to dentate (or blade deltate, less than 1 cm, base abruptly narrowed to petiole). Racemes usually elongated. Petals white, (9–) 11–15 mm, often 2 times as long as sepals. 2n = 12.
