Recent and new taxonomic acquisitions in some native genera of Asteraceae from southern Italy and Sicily
2021
After a brief review of the recent acquisition in some native genera of family Asteraceae from southern Italy and Sicily, a new endemic species of Anthemis (sect. Hiorthia) is described from Sicily and named Anthemis parlatoreana. The locus classicus of the new taxon, falling in the NW Tyrrhenian coast of the island (Castellammare del Golfo, Trapani), coincides with that of Ptilostemon greuteri, another endemic very rare species of the Sicilian flora. Data on the morphology, distribution, ecology and conservation status of the new species are provided. The taxonomic relationships with the other Sicilian taxa of the same section, in particular A. cupaniana, are also analyzed. The simultaneou…

Karyological data of some plant species native to South Italy
2019
The somatic chromosome number, karyotype morphology, geographical distribution and ecology of five plant species from the indigenous flora of southern Italy and Sicily are presented. The study includes in particular four species of Allium subgen. Allium (Allium agrigentinum, A. apulum, A. diomedeum, A. chamaespathum), Ptilostemon greuteri and Salvia ceratophylloides. Five out six of these species are strict endemics and all of them are very rare and differently threatened based on the IUCN criteria. Karyotype microphotographs for all taxa are provided and their karyotype morphology is discussed.
