Description
Rhexia virginica is a perennial herbaceous species.
"Erect, herbaceous, hermaphroditic, cymose perennials. Leaves opposite, sessile or petioles to 2 mm long. Flowers 4-merous, floral parts perigynous; stamens 8, anthers 1-locular, poricidal, usually with a basal spur. Capsules globose or subglobose; hypanthium cylindrical in anthesis, urceolate at maturity; stipes or pedicels 2-4.5 mm long; seeds brownish or yellowish, crescent-shape, papillose lined, 0.5-1 mm long except for R. petiolate and R. alifanus." - Radford et al 1964
"Hirsute, usually branched perennial; roots usually tuberous; stems to 9 dm tall, faces equal, winged. Leaves elliptic or ovate, to 7 cm long and 2.6 cm wide, sparsely hirsute, 3-nerved, acute or aristate, ciliate-serrate, base cuneate. Sepals deltoid, 1.5-3 mm long, aristate; petals rose-purple, glandular hirsute marginally beneath, 10-25 mm long, usually mm long, usually glandular hirsute, neck shorter than body." - Radford et al 1964
