NEMOPHILA

Robert Patterson & Richard R. Halse


Annual. Stem: simple to branched, prostrate to erect, fleshy, brittle, angled or winged, glabrous to generally bristly (prickly). Leaf: simple, cauline, lower generally opposite, upper opposite or alternate, generally reduced; petiole generally bristly-ciliate; blade pinnate-toothed or -lobed, generally bristly. Inflorescence: flowers 1 in leaf axils or opposite leaves; pedicels longer in fruit, recurved. Flower: calyx bell-shaped to rotate, sinuses generally with spreading or reflexed appendages; corolla bell-shaped to rotate, white, blue, or purple, spotted or marked or not; stamens included; ovary chamber 1, style 1, generally 1/3–1/2 forked. Fruit: generally 2–7 mm wide, spheric to ovoid, hairy, generally enclosed by calyx. Seed: ovoid, smooth, wrinkled or pitted, with a conic, colorless appendage at 1 end.
11 species: southeastern United States, western North America. (Greek: woodland-loving)
