Claytonia virginica Linnaeus var. virginica . Spring-beauty. Phen: (Jan-) Feb-Apr (-May). Hab: Moist forests, lawns. Dist: NS west to MN, south to GA and TX.

Origin/Endemic status: Native

Taxonomy Comments: Differences in ploidy and subtle differences in morphology have been used to differentiate two varieties in the more widespread white-to-pink-flowered plants, and this may be warranted but needs more careful study using modern techniques. Var. virginica has chromosome numbers of n=8 and polyploid and polyploid/aneuploid derivatives of that number, broader leaves [the widest leaves on a plant 5-10 (-20) mm wide], and a broader distribution (NS west to MN, south to sw. GA and TX. Var. acutiflora A.P. de Candolle has chromosome numbers of n=6, n=7, and polyploid and polyploid/aneuploid derivatives of those numbers, narrower leaves [the widest leaves on a plant 1-2 (-4) mm wide], and a more restricted, southerly distribution (north to VA and IL). Wide-leaved plants, corresponding to C. virginica f. robusta (Somes) Palmer & Steyermark, have been confused with plants of both C. arkansana and C. caroliniana in Arkansas in the past.
