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.
