Allium paniculatum L., una specie critica ed erroneamente interpretata della flora europea
2010
Dalle indagini morfologiche e cariologiche condotte è emerso che Allium paniculatum è una specie ben differenziata dagli altri taxa della sez. Codonoprasum, con corredo cromosomico poliploide, esaploide o triploide, probabilmente originatosi in seguito all’adattamento ad ambienti sinantropici in territori con bioclima marcatamente mesico, come si desume dalle esigenze ecologiche, dal periodo di fioritura estivo e dalla distribuzione geografica.
A new species of Smyrnium (Apiaceae) related to S. perfoliatum
2015
On the basis of plant collections recently carried out in Sicily as well as the study of the herbarium material kept in PAL and PAL-Gr, a new species of Smyrnium (Apiaceae) is described here. This new taxon, named Smyrnium dimartinoi, is related to S. perfoliatum and is presently known from Sicily, Crete and realistically elsewhere in the Mediterranean. In such range it occurs in open woods and clearings of the Mediterranean-temperate and submontane belt.
The unnoticed northward expansion of Najas marina subsp. armata (Hydrocharitaceae) in the Mediterranean area: an effect of climate change?
2022
Recent reports of Najas marina L. (Hydrocharitaceae) from Sicily have been interpreted as a confirmation of its presence on the island, where it was earlier mentioned in the 1800s. However the recent finds do not represent “N. marina” (currently N. major All.) but N. marina subsp. armata Horn (= N. delilei Rouy), a different taxon, previously not recorded from Sicily. According to those reports and several new finds presented here, it appears to be invading reservoirs and lakes in southern Sicily and seems to be naturally expanding its range. Climate change is suggested as possible cause of this shift. The same trend appears to be taking place across the whole N Mediterranean area, from Por…
