Key to Commelinaceae
Inflorescence: flowers 1 or in few-flowered clusters, subtended by 1 ± leaf-like bract.
Flower: bilateral; 2 petals larger, [generally blue or] pale violet, 1 smaller, paler; filaments glabrous.
± 170 species: tropics, warm temperate. (Jan, 1629–1692, and nephew Kaspar, 1667–1731, Commelijn, Holland)

Unabridged note: According to Linnaeus (1737, Critica Botanica; pp. 62–63 in translation by A. Hort, 1938) and Tucker (1989, Journal of the Arnold Arboretum 70:97–130) the genus was named for 3 members of the Commelijn family, 2 of whom (Jan and Kaspar) became famous botanists and are represented by the 2 large, showy petals; the third member (Kaspar, Jr., 1700–1734, son of Kaspar) died without having accomplished anything in Botany and is represented by the third, small, not showy petal. According to Tucker, Wijnands (1983, The Botany of the Commelins. viii + 232 pp. 64 plants. Rotterdam) contends that the genus name actually was adopted by Plumier, who probably was not aware of Kaspar, Jr.
Stem: ascending to decumbent or occasionally straggling, nodes rooting.
Leaf: 2–9 cm, ovate to lance- elliptic; sheath with ± red hairs at tip; margins generally wavy, hairy.
