Notes on Corsican flora, XXV.
These "notes" deal with 110 noteworthy taxa amongst which 21 are new to the island's flora. One of these taxa is native: Reseda alba subsp. hookeri and 20 are introduced: Abies pinsapo, Acer × coriaceum, Albizia julibrissin, Arundo micrantha, Azolla filiculoides, Bolboschoenus laticarpus, Digitaria ciliaris, Digitaria violascens, Eucalyptus camaldulensis, E. globulus, Genista januensis subsp. lydia, Hedera helix subsp. maroccana, Morus kagayamae, Oenothera rosea, Paspalum vaginatum, Puccinellia festuciformis subsp. lagascana, Silene fuscata, Solanum mauritianum, Veronica filiformis and Vitis riparia × V. rupestris. The presence of Aegilops ventricosa and Legousia speculum-veneris is presently confirmed. However Carex praecox, Eleocharis quinqueflora, Herniaria hirsuta subsp. cinerea, Juncus acutiflorus and Juncus compressus must be deleted from the Corsican Flora due to their confusion with other related taxa. New localities are given for 48 taxa considered as "very rare" (RR) out of which 10 become "rare" (R) on the one hand, and for 23 taxa considered to be "rare" (R) out of which 12 change their status from "rare" to "not common" (PF) or "localised" (LOC), on the other. Finally, the data published for the 12 remaining taxa (considered as "localised" (LOC) or "not common" (PF)) constitute a considerable increase of our knowledge about their distribution. The new sites often correspond to new sectors for these taxa. Fourteen out of 110 taxa are endemic, 11 are part of the red list and 44 are xenophytic species. A distribution map is also provided for Carex extensa and Cerastium siculum.
