Species Description - Lvs firm, mostly broadly elliptic to subrotund, 2.5–7 cm, broadly rounded above, rounded to truncate or short-cuneate at base, and always somewhat decurrent on the petiole; scapes 1.5–3 dm, usually with 1 or 2 scale-lvs; sep oblong or ovate-oblong, 3–4 mm, nearly twice as long as wide, erose or undulate, not overlapping at base; pet white, 8–10 mm; anthers 3–3.5 mm, minutely cuspidate at base, abruptly narrowed into very short tubes above; style declined; 2n=46. Dry or moist woods and bogs; circumboreal, s. in Amer. to N.C., Ky., Ind., and Minn. July, Aug. Our plants are nearly all var. americana (Sweet) Fernald, as described above.
