Style swollen distally; stigma lobes erect, not grooved. Capsules: apex rounded, truncate, or short-apiculate. 2n = 48.

Flowering spring. Usually deciduous wet-mesic to dry-mesic woods of bottomlands and uplands, slopes of ravines, lower ledges of bluffs, often near waterways, often in loamy soils; 0--900 m; N.B., Nfld. and Labr., N.S., Ont., Que.; Conn., Del., Ga., Ill., Ind., Iowa, Ky., Maine, Md., Mass., Mich., Minn., Mo., N.H., N.J., N.Y., N.C., Ohio, Pa., R.I., S.C., Tenn., Vt., Va., W.Va., Wis.

Infrequent to frequent throughout the state. Like the preceding species, where it is found it usually forms dense colonies because of its mode of reproduction. After the seed germinate, it usually takes four years' growth to produce a flower. The seedling, from the beginning of the second year, produces annual crops of runners and bulbs, each going deeper until the necessary depth, size, and vigor are reached to produce a flower, in addition to the leaf buds which have been produced each previous year. Considering the great number of single-leaf plants, the number of flowering ones is small. This species prefers rich, moist soil of wooded slopes in beech and sugar maple woods. It is found also in rich soil in almost all kinds of woods and is often abundant on alluvial wooded plains. In Indiana it is more frequent than the preceding species [Erythronium albidum].
