Notes et contributions à la flore de Corse, XXIII

These “notes” deal with 102 noteworthy taxa amongst which 12 are new introduced species to the island’s flora: Chamaerops humilis, Bothriochloa barbinodis, Anthemis cretica subsp. cretica, Arctotheca calendula, Crepis nicaeensis, Leontodon hispidus subsp. hispidus, Soliva sessilis, Saponaria ocymoides subsp. ocymoides, Silene italica, Euphorbia cyparissias, Anthyllis vulneraria subsp. carpatica and Physalis peruviana. New localities are given on one hand for 39 taxa considered as “very rare” (RR) out of which 9 (Freesia alba, Serapias strictiflora, Elytrigia repens, Hordeum marinum subsp. marinum, Crepis bursifolia, Crepis foetida subsp. rhoedifolia, Gleditsia triacanthos, Fumaria flabellata and Galium minutulum) become “rare” (R). On the other hand 18 taxa considered to be “rare” (R) out of which 9 (Asplenium foreziense, Pulicaria vulgaris, Cerastium brachypetalum subsp. tauricum, Spergula arvensis subsp. chieusseana, Stellaria alsine, Melilotus sulcatus, Centaurium pulchellum, Hypericum androsaemum and Fumaria bicolor) change their status from “rare” to “not common” (PF) or “localised” (LOC). Finally, the datas published for the 31 remaining taxa (considered “localised” (LOC) or “not common” (PF) taxa) constitute a considerable increase of our knowledge about their distribution. The new sites correspond often to a new sector for the presence of a given taxon. 13 of the whole lot of 102 taxa are part of the red list and 26 are xenophytic species. A distribution map is also provided for Hordeum marinum subsp. marinum and Spergula arvensis susbp. chieusseana
