Current name: Iva annua L. ( Asteraceae).
Note: Iva annua was treated as the generitype by Britton & Brown (Ill Fl. N U. S., ed. 2, 3: 338. 1913; see McNeill & al. in Taxon 36: 375. 1987). However, under Art. 10.5, Ex. 7 (a voted example) of the Vienna Code, this is a type choice made under the American Code and is to be replaced under Art. 10.5b by Green’s choice (Prop. Brit. Bot.: 188. 1929) of I. frutescens L.
