John W. Thieret, final revision by Thomas J. Rosatti

[Annual to] perennial herb [to tree], generally ± glabrous. Leaf: alternate, simple, entire, generally petioled; stipules 0 or vestigial. Inflorescence: spike, raceme [panicle], [axillary or] terminal (then often lateral, ± opposite a leaf, by growth of bud axillary to that leaf); bract 1; bractlets 2. Flower: generally bisexual, radial; sepals [4]5[10], fused at base, generally persistent; petals 0; stamens 4–many, generally on disk, free or fused at base, in 1–2 whorls or not; carpels generally 1–12, [free] to fused, ovary generally superior, carpels = styles, chambers in number, ovules 1 per chamber, stigmas linear or thread-like. Fruit: berry [achene, capsule, drupe, nut, samara].
± 18 genera, 130 species: ± worldwide, especially America tropics, subtropics. [Rogers 1985 J Arnold Arbor 66:1–37] A broad family concept adopted here, as many as 6 segregate families sometimes recognized by others. —Scientific Editor: Thomas J. Rosatti.
