Wigandia

Wigandia is a genus of flowering plants within the family Namaceae. They are found mainly in Central America and South America, though one or two species are found as far north as the United States. Some are grown as ornamental plants and will flourish in most Mediterranean or temperate regions. The genus is named for Johann Wigand (c. 1523–1587), German Lutheran cleric and theologian, and Bishop of Pomesania. Formerly placed in the family Hydrophyllaceae, Wigandia species are unusual in having minute seeds and a high base chromosome number (19); it is also the only neotropical genus in the group. Some species originally classified in Wigandia are now treated in other genera, e.g. Eriodictyon. A 1998 molecular phylogenetic analysis included two Wigandia species (W. caracasana and W. urens, now considered synonymous), and confirmed that they lay within a clade that includes Eriodictyon, and also the genera Nama and Turricula (now synonymized with Eriodictyon).
