Stem underground or prostrate to erect
Leaves generally simple, generally cauline, generally opposite; stipule generally 0; blade generally glabrous, often glaucous
Inflorescence: cyme or flower solitary
Flower generally bisexual, radial; hypanthium present; sepals 3–8; petals generally many in several whorls, free or fused at base, linear, sometimes 0; stamens 1–many, free or fused in groups, outer often petal-like; nectary a ring or separate glands; pistil 1, ovary superior to inferior, chambers 1–20, placentas generally parietal, styles 0–20, stigmas 1–20

Bolus: ovary glands convex and minutely crenate, stigmas densely plumose, fruit chambers 5, seeds ovate, ± smooth; Lampranthus species: ovary glands fused, fruit chambers 5, seeds pear-shaped, ± black, rough; both genera members of Ruschieae)
