Perennial [ subshrub], stellate-hairy; caudex woody.
Stem: generally > 1, 0.6–2 m, branched.
Leaf: stipules inconspicuous, persistent or not; blade generally 3–7 lobed, base wedge-shaped, truncate, or cordate.
Inflorescence: spike- or raceme-like, flowers 1 in lower leaf axils, 2–5 in upper leaf axils, leaves reduced above; bractlets 3, free, linear to lanceolate, ± persistent.
Flower: showy; calyx 5-lobed, divided 1/2, stellate-hairy to ± glabrous; petals 5, pale lavender to rose-purple, pink, or white; filament tube with anthers in upper 1/3–1/2; styles generally 6–15, stigmas generally oblique-squared, often ± elongate.
Fruit: generally > calyx; oblong; segments generally 6–15, generally 10–15 mm, 6–10 mm wide, beaked or not, attached to fruit axis by strong fiber, ± dehiscent to base, bristly, sides thin, smooth, glabrous.
Seed: generally 2–4 per segment, reniform, glabrous to puberulent.
8 species: North America. (derivation uncertain)
Unabridged etymology: (coined by E.L. Greene, derivation uncertain, perhaps Greek, meaning Trojan; or named after Lake Iliamna in AK; or after Illi-nois and Indi-ana, where 1 sp. is endemic)
