Herbs; stems herbaceous or suffrutescent, reclining or ascending, pubescent with spreading trichomes. Leaves oblong, elliptic-oblong or lanceolate, 1-2.5 cm long, mostly less than 1 cm wide, subsessile, acute to obtuse basally and apically, pubescent. Flowers on peduncles mostly equaling the leaves; sepals lanceolate, acute or acuminate, 2-3 mm long, pubescent; corollas mostly pale blue, sometimes white, 3-7 mm broad; ovary glabrous. Fruits capsular, globose, glabrous; seeds black, smooth.
Annual or perennial herb; thinly or sometimes densely covered with long, patent, silky hairs. Stems decumbent or erect. Leaves with blade elliptic, ovate-oblong, narrowly ovate to linear-oblong, mucronate. Flowers: peduncles axillary, 1-few-flowered; style bifid with 2 subpeltate, bilobed stigmas; corolla rotate to broadly funnel-shaped, shallowly lobed, 6-8 mm long, blue, rarely white; Jul.-Jun. Fruit a globose-depressed, glabrous capsule, 3-4 mm long.
Slender, prostrate or ascending, 2–4 dm, thinly appressed-hairy; lvs scattered, commonly shorter than the internodes, spreading, oblong, 1–2 cm; fls numerous, either solitary or few together at the end of filiform, spreading peduncles longer than the subtending lvs; cor pale blue to white, rotate, 6 mm wide; 2n=26. A weed in the warmer parts of the world, intr. in Mo. Spring–summer.
