Etymology: Vernonia is named after William Vernon, an English botanist who collected plants in North America in the late 1600s. The genus was established by the Scottish-born botanist Charles Plumier's contemporaries, and it was formally named by Carl Linnaeus, who published the name in 1737 in his "Hortus Cliffortianus." Linnaeus chose it to honour Vernon, who had sent specimens from the Carolinas and Virginia to English gardens and collectors. The name followed the usual botanical habit of commemorating a collector, so the word itself has no meaning beyond the man it recalls. The "-ia" ending is the standard Latinized form used for plant genera named after people, so "Vernonia" is simply "Vernon" made into a Latin-style name. Many of its members are not tropical at all: the genus includes North American ironweeds, whose purple flower heads brighten meadows and roadsides in late summer, alongside species from Africa, Asia and South America.
