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., Published as part of Santangelo, Annalisa, Guglielmone, Laura & Troia, Angelo, 2022, Typification of the names Anethum pusillum and Meum segetum (Apiaceae), pp. 206-210 in Phytotaxa 554 (2) on page 206, DOI: 10.11646/phytotaxa.554.2.9, http://zenodo.org/record/6820999, {"references":["Allioni, C.

Meum segetum Guss. (Gussone 1827: 346) ≡ Ridolfia segetum (Guss.) Moris (1841: 212). Type (lectotype, designated here):—[ITALY. Sicily] “ Ridolfia segetum Moris en. Sem. H. Taur. anno 1841. Guss. Syn. 1 p.312. Meum segetum Guss. Pr. 1 p.346. Anethum segetum Lin. Mant. 219? Aprili, Majo., Annual. Inter segetes ubique/ Palermo” Gussone Sicilia Collection (NAP [without number]). Fig. 2. [≡ Anethum ridolfia Spalik & Reduron in Frankiewicz et al. 2021: 19]. Note on the typification: In the herbarium BOLO there is a specimen [without number] collected by Gussone that was received by Bertoloni in 1822. It perfectly agrees with the description in Bertoloni (1838). This specimen is not suitable for typification because it indicates the distribution in South Italy (“nei campi coltivati di Sicilia, e di Calabria ” – whereas the protologue refers to Sicily only) and not a gathering locality. Specimens collected by Gussone are not present at FI and PAL. In Gussone Sicilia Collection at NAP, twelve specimens of Ridolfia segetum from several localities are preserved. As usual in Gussone Collection (see Pasquale 1871, La Valva, 1993), only the first sheet of the series has detailed label with all the nomenclatural, ecological, and distributional data. Separate labels with “field” data are put together in the first sheet or in the next ones. Duplicate specimens originally don’t bear label. In this case, only later Giuseppe Antonio Pasquale, student and disciple of Gussone, added the labels with indication of date, place of gathering, and collector in the duplicates of Gussone Collections (Pasquale 1871, La Valva, 1993, Santangelo et al. 2005). Moreover, Gussone began to add on the label the date of collection only after 1824. In this sense, almost all the specimens of R. segetum in Gussone Sicilia collection can be considered original material; in fact, only one specimen bears the label with the indication of the date of gathering (28 giugno 1841), all the other ones reporting only the gathering localities, showing that they have been collected by Gussone before 1824. We selected the first sheet of the series as lectotype. Note that we consider the second sheet (Fig. 3), with its label written by Pasquale (as above), as a duplicate of the first one, and so an isolectotype. Taxonomic note: It is definitely clear that Meum segetum is not synonym of Anethum segetum Linnaeus (1771: 219) (typified by Jarvis et al. 2006 and by the same authors considered synonym of Anethum graveolens L.), and that it is the basionym of the name Ridolfia segetum proposed by Moris (as correctly reported by Hand 2011). This also to complete the synonyms reported in Frankiewicz et al. (2021), where Ridolfia segetum is reported as the basionym (and the only synonym) of the new name Anethum ridolfia Spalik & Reduron. The main character differentiating Anethum ridolfia (≡ Meum segetum ≡ Ridolfia segetum) from Anethum graveolens (= Anethum segetum) is the fruit, smooth and without ribs in the former, with three ribs in the latter., Published as part of Santangelo, Annalisa, Guglielmone, Laura & Troia, Angelo, 2022, Typification of the names Anethum pusillum and Meum segetum (Apiaceae), pp. 206-210 in Phytotaxa 554 (2) on pages 206-208, DOI: 10.11646/phytotaxa.554.2.9, http://zenodo.org/record/6820999, {"references":["Gussone, G., (1827) Florae Siculae Prodromus sive Plantarum in Sicilia Ulteriori Nascentium Enumeratio Secundum Systema Linnaeanum Disposita, Vol. 1.
