A Nomenclatural and Taxonomic Revision of the Senecio squalidus Group (Asteraceae)

Abstract

Senecio squalidus (Asteraceae) currently includes nine subspecies distributed in North and Central Europe and in the Mediterranean basin. Within this taxonomic aggregate, many species have been described, but research on their nomenclatural types is incomplete. A complete nomenclatural survey of 19 names belonging to this taxonomically critical group was carried out. Fourteen lectotypes are here designated. The nomenclatural analysis, complemented by field investigations in the type localities of the taxa described in the Central Mediterranean, allowed us to accept 10 species. Accordingly, we proposed here a new name and a new missing combination at a specific level: S. aknoulensis and S. calabrus.

Phlomis lychnitis (Lamiaceae), una adición a la flora de África desde Marruecos

“…The flora of Morocco still brings new discoveries due to its climatic and topographical diversity, and the complexity of its territory. Since the publication of the last volume of the Flore Pratique du Maroc (Fennane et al, 2014), more than 30 new species have been described (Alonso et al, 2015;Andrés-Sánchez et al, 2015;Brullo et al, 2015Brullo et al, , 2017Chambouleyron et al 2015;Dobignard, 2015;Talavera et al, 2015;Vigalondo et al, 2015;Crespo et al, 2016;Sutorý, 2016;Gonçalves, 2018;Gutiérrez-Larruscain et al, 2018;Khamar et al 2018;Martínez-Laborde, 2018;Mejías et al, 2018;Hassemer, 2019;Koch & Lemmel, 2019;Chatelain et al 2020;Martínez Labarga & Ferrer-Gallego, 2020;Vicente et al, 2020;Frankiewicz et al, 2021;Homrani-Bakali & Susanna, 2021Romo, 2021;Barone et al, 2022). This highlights the importance of conducting field explorations.…”

New Data on Native and Alien Vascular Flora of Sicily (Italy): New Findings and Updates

“…After the latest checklists of the Sicilian [1,2] and Italian native and alien vascular flora [3][4][5], several new contributions have been published for Sicilian flora. Some of these refer to newly described endemic species [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22], while others confirm or record for the first time species native to the island [23][24][25][26][27][28][29][30][31][32]. However, the large majority of these contributions consist of reports of exotic species .…”
