Erythronium umbilicatum C.R. Parks & Hardin ssp. umbilicatum . Dimpled Trout Lily. Phen: (Late Jan-) Feb-Apr (May?); Apr-Jun. Hab: Moist bottomland or slope forests, or in rather dry upland habitats. Dist: VA and e. WV south through NC, SC, and e. TN to c. GA, e. AL, and Panhandle FL.

ID notes: Where sympatric with Erythronium americanum ssp. americanum, Erythronium umbilicatum ssp. umbilicatum blooms about 2 weeks earlier on average, has a slightly oranger, deeper yellow flower color, and can be distinguished in flower or fruit by the shape of the ovary summit (see key).

Origin/Endemic status: Endemic

Taxonomy Comments: E. umbilicatum ssp. umbilicatum is a diploid (2n = 24). Mathew (1992) suggests the possibility that an earlier name, E. nuttallianum Roemer & J.A. Schultes, may apply to this taxon; the two locations mentioned on the type, Pennsylvania and Albany, NY, are outside the known range of the species, however.

Synonymy: = FNA26, GW1, K1, K3, K4, Va, Mathew (1992), Parks & Hardin (1963); < Erythronium americanum Ker Gawl. – F, G, RAB, S, S13; < Erythronium umbilicatum C.R.Parks & Hardin – C, Tn, W, WH3, WV
