[Annual, perennial herb to] shrub, [tree], nodes generally swollen. Leaf: simple, generally opposite, entire (toothed [lobed]); stipules 0. Inflorescence: variable, with bracts, generally also bractlets. Flower: bisexual; calyx deeply (3)4–5 lobed [(sepals free)]; corolla 4–5 lobed, radial to 2-lipped; stamens 2 or 4, epipetalous, anther sacs sometimes dissimilar in size or placement; ovary superior, 4–many-ovuled, chambers 1–2, placentas axile (free central), stigmas 1–2. Fruit: capsule, loculicidal, generally dehiscing explosively, valves 2. Seed: 1–4[+], each generally subtended by hook-like outgrowth that remains in fruit.
220 genera, 4000 species: especially tropics; some ornamental: Justicia (Beloperone, shrimp-plant), Acanthus, Thunbergia. [Daniel 1998 Proc Calif Acad Sci 50:217–256; Hilu et al. 2003 Amer J Bot 90:1758–1766; Schwarzbach & McDade 2002 Syst Bot 27:84–98] —Scientific Editor: Thomas J. Rosatti.

Key to Acanthaceae
Shrub [to tree]; roots spreading, exposed at low tide. Leaf: persistent, petioled; blade thick. Inflorescence: axillary, terminal, head-like, < peduncle; bractlets 3, generally < calyx, outer 1 > inner 2. Flower: calyx deeply 5-lobed; corolla 4-lobed, radial, rotate; stamens 4, attached at 1 level. Fruit: ellipsoid to ovoid, often asymmetric, 1-chambered, generally indehiscent; stalk not flat.
± 8 species: temperate, subtropics worldwide, generally coastal marshes, lagoons. (Avicenna, Persian physician, philosopher, 980–1037) [Duke et al. 1998 Evolution 52:1612–1626] Placement in Acanthaceae s.l. fairly well established; sister group relationship with Thunbergioideae weakly supported (Schwarzbach & McDade 2002; Hilu et al. 2003).
