Anethum pusillum All. (Allioni 1773: 28). Type (lectotype, designated here - or perhaps holotype): [No locality] “ Anethum pusillum segetum L.” Allioni Collection (TO [without number]), Fig. 1. [= Anethum graveolens Linnaeus (1753: 263); Lectotype (Jansen 1981: 34): Herb. Linn. No. 371.1 (LINN)]. Note on the typification:— Dal Vesco (1986) reported A. pusillum among those species represented in Allioni collection by more than one sheet. Actually, we were able to find only one specimen with that name in the Allioni collection (TO), but we cannot conclude that other specimens do not exist and cannot be found in the future. That’s why we choose this specimen as the lectotype. Taxonomic note: The observation of the unripe fruits in the specimen, selected in this work as the lectotype, suggests it corresponds to A. graveolens, so that A. pusillum is not synonymous with “ Ridolfia segetum (Linnaeus 1771: 219) Moris (1841: 43) ” as proposed by Chiovenda (1912), dubitatively by Dandy (1970), and more recently by POWO (2022) and WCVP (2022). However, this latter name has to be cited more correctly as Ridolfia segetum (Gussone 1827: 346) Moris (1841: 43) (see below). Incidentally, also the other two specimens of A. segetum in the Allioni collection (TO) have to be referred to A. graveolens.
