Family	Commelinaceae	Dayflower or spiderwort family
Genus	Commelina	After Dutch botanists Jan (1629-1692) and his nephew Caspar (1667-1731) Commelijn, known to Linnaeus and Charles Plumier, a French Franciscan monk, botanist and traveler who apparently named this flower. Jan, or Johan, Commelijn was a doctor and the director of botany at the Hortus Medicus (Medical Garden) in Amsterdam, who worked with many Asian tropical plants sent back to Holland. Linnaeus allegedly decided to commemorate the Commelins because the dayflower has two large petals (for Jan and Caspar) and a third small petal (for another Commelijn who died young before he could accomplish anything in botany), but this may well be an apocryphal though convenient explanation
