8. Tradescantia virginiana L. (Virginia spiderwort, widow=s tears)

Pl. 27 b, c; Map 114

Stems 5B40 cm long, straight or slightly zigzag, glabrous or sparsely and inconspicuously hairy. Blades of the leaves and bracts 10B40 cm long, linear-lanceolate, as broad as or narrower than the sheaths, deep green, glabrous or less commonly sparsely hairy. Flower stalks 15B35 mm long, pubescent with nonglandular hairs. Sepals 9B15 mm long, green, usually herbaceous and somewhat inflated, densely pubescent with nonglandular hairs. Petals 12B18 mm long, deep purple to purplish blue, less commonly reddish pink. 2n=12, 24 (both in Missouri, but the diploid apparently only north of the Missouri River [Anderson, 1954]). AprilBJune.

Scattered in the eastern half of the state (northeastern U.S. south to Georgia and west to Missouri). Mesic to dry upland forests and shaded ledges of bluffs, frequently in open rocky woods, uncommonly at the edge of glades, mostly on acidic substrates; also along railroads.

Known to hybridize rarely with T. ohiensis. A single specimen from a roadside in Newton County that is apparently referable to this species may represent an escape from cultivation.
