The vascular plants of Kálamos (Ionian Islands, Greece): A catalogue

During a field trip on the Ionian island of Kálamos in 1997, a total of 505 taxa of vascular plants were recorded, of which 346 are additional to those recorded by Baliousis & Yannitsaros 2010, resulting in 568 species now known from that island. They are documented in a catalogue with reference to localities. The first indication for the Ionian Islands is reported for Linaria simplex. Asphodelus fistulosus and Verbascum densiflorum are new for the prefecture of Lefkádha. Additional (mainly taxonomical) notes concern Ajuga chamaepitys, Anchusella cretica, Arenaria serpyllifolia agg. (A. leptoclados, A. leucadia), Charybdis maritima, Cerastium semidecandrum, Cistus creticus, Clinopodium officinale, Ficaria verna agg., Geranium brutium, Helianthemum nummularium, Linum spicatum, Portulaca oleracea agg., Oloptum thomasii (Piptatherum th.), Saponaria aenesia and S. calabrica, Scorpiurus subvillosus, Stachys ionica, and Trifolium xanthinum. New nomenclatural combinations are Arenaria leptoclados subsp. peloponnesiaca (Rech. f.) Guterm. (Caryophyllaceae), Clinopodium officinale (Moench) Guterm. (Lamiaceae), Festuca incurva (Gouan) Guterm. (Poaceae), Oloptum thomasii (Duby) Guterm. (Poaceae) and Stellaria neglecta subsp. cupaniana (Jord. & Fourr.) Guterm. (Caryophyllaceae). For Anchusella cretica, A. variegata, Galium ionicum and Ornithogalum collinum the distribution within the Ionian Islands is presented as grid maps.
