Young stems terete, angled or winged. Rhizomatous, or tuberous. Helophytic to xerophytic. Leaves opposite (at the base of the stem), or alternate to whorled (above); when alternate, spiral; petiolate to sessile; non-sheathing; gland-dotted; simple. Leaf blades entire; pinnately veined; cross-venulate. Leaves without stipules; without a persistent basal meristem. Leaf anatomy. Hydathodes present. Stem anatomy. Nodes unilacunar. Secondary thickening absent, or developing from a conventional cambial ring, or anomalous.

Reproductive type, pollination. Fertile flowers hermaphrodite. Unisexual flowers absent. Plants hermaphrodite. Entomophilous.

Inflorescence and flower features. Flowers solitary; axillary; pedicellate (usually); bracteate; ebracteolate; small, or medium-sized; regular; (4–)5 merous; cyclic; tetracyclic. Free hypanthium absent. Perianth with distinct calyx and corolla; (8–)10; 2 -whorled; isomerous. Calyx (4–)5; 1 -whorled; gamosepalous; deeply lobed; contorted; regular; persistent (free from the ovary); with the median member posterior. Corolla (4–)5; 1 -whorled; not appendiculate; gamopetalous; lobed. Corolla lobes markedly longer than the tube. Corolla imbricate; very shortly campanulate, or rotate; regular; white, or red, or pink, or blue. Corolla members entire. Androecium 5. Androecial members adnate (to the corolla); free of one another; 1 -whorled. Androecium exclusively of fertile stamens. Stamens 5; isomerous with the perianth; alternisepalous. Filaments hairy (often villous), or glabrous. Anthers dorsifixed; versatile; dehiscing via longitudinal slits; introrse; tetrasporangiate. Gynoecium supposedly 5 carpelled. The pistil 1 celled. Carpels isomerous with the perianth. Gynoecium syncarpous; eu-syncarpous; superior. Ovary unilocular; 1 locular (and no evidence of partitions). Gynoecium stylate.
