Alan T. Whittemore & L.L. Gaddy in Flora of North America (vol. 3)
Rhizomes: internodes short, leaves crowded at rhizome apex. Leaf blade variegate or not, cordate, subcordate, or subreniform. Flowers: calyx tube cylindric to narrowly cylindric-urceolate, sometimes with prominent transverse ridge just below sinuses, 8-15 × 6-12 mm, inner surface with high reticulations, lobes erect or weakly spreading, 2-4 × 7-9 mm, adaxially puberulent; stamen connective not extending beyond pollen sacs; ovary ca. 1/3-inferior; ovules 8 per locule; styles notched at apex. 2 n = 26. Flowering spring (Apr-Jun). Deciduous and mixed deciduous-conifer forests; 0-700 m; Ky., Md., N.C., Tenn., Va., W.Va. Plants of Hexastylis virginica with small, cylindric-urceolate calices have been treated as a distinct species, H . memmingeri . The two calyx types are often found in the same population, however, so H . memmingeri seems unworthy of taxonomic recognition at any rank. Prior to the study by H. L. Blomquist (1957), many botanists interpreted Hexastylis virginica in a very broad sense, so old herbarium specimens of many other species of Hexastylis are often annotated as H . virginica .

The Cherokee used Hexastylis virginica medicinally to stop blood from passing (D. E. Moerman 1986, as Asarum virginicum ).

Vascular plants of NE US and adjacent Canada
Rhizome short and freely branched; lvs cordate-orbicular, 5-10 cm, commonly broadest above the summit of the petiole, the basal lobes broadly rounded, the sinuses broad to narrow or even closed; cal-tube 0.7-1.5 cm, cylindric to slightly constricted above or slightly flaring, the lobes erect to spreading 3-10 mm, 5-9 mm wide at base; ovary superior to half inferior; style- extension merely notched at the tip; 2n=26. Moist or dry woods; s. Md. to W.Va. and e. Ky., s. to se. Va., Ga., and Ala. Apr., May. (H. contracta; H. heterophylla; H. memmingeri; H. naniflora)
