Herbs, erect, ascending, or occasionally decumbent, rarely rooting at nodes. Stems often much branched distally, 15–60 cm; internodes not at all to slightly glaucous, glabrous. Leaves spirally arranged, sessile, forming nearly right angle with stem, straight; blade narrowly oblong-elliptic to linear-lanceolate, 4–11(–20) × 0.4–1.2 cm (distal leaf blades equal to or narrower than sheaths when sheaths opened, flattened), base often constricted, apex acuminate, not at all to slightly glaucous, glabrous. Inflorescences terminal, often axillary; bracts foliaceous. Flowers distinctly pedicillate; pedicels 0.8–1.5 cm, glabrous; sepals 0.6–0.8 mm, glabrous or with apical tuft of eglandular hairs; petals distinct, pale blue, ovate, not clawed, 1.3–1.5 cm; stamens free; filaments bearded. Capsules 2–5 mm. Seeds 2–3 mm. 2n = 12.
Phenology: Flowering spring (Mar–May), sporadically to early fall.
Habitat: Alluvial bottoms and swamps, forests, roadsides, railroad rights-of-way, fields, ditches, and lawns

Discussion
Tradescantia paludosa is clearly Anderson and Woodson's weakest species, and D. T. MacRoberts (1979) may be correct in treating it as a variety of Trandescantia ohiensis. In view of its importance as a research tool, however, I prefer to maintain T. paludosa as a species until a more rigorous analysis of its variation is published. Plants of this species do not seem to require a winter dormancy, hence they can be cultivated in greenhouses year-round.
