Abstract

The flora of three small islets located in the Korčula Archipelago was investigated on several occasions during 2020. In all, 105 plant taxa were recorded, of which 101 are angiosperms, 3 gymnosperms and with 1 fern. The total flora of the islets is distributed in 48 families. The families with the highest number of taxa are Poaceae (12.38%) and Asteraceae (10.48%), followed by Lamiaceae (7.62%) and Fabaceae (5.71%). The most common life forms are therophytes (31.43%), hemicryptophytes (27.62%) and phanerophytes (19.05%). The largest number of plant taxa is accounted for by the Mediterranean floral element (60.95%), followed by the South European (20.00%) In all, three endemic, four endangered and seven strictly protected taxa were recorded. Endemics are Carduus micropterus (Borbás) Teyber ssp. micropterus, Vincetoxicum hirundinaria Medik. ssp. adriaticum (Beck) Markgr and Limonium dictyophorum (Tausch) Degen. All recorded endemic taxa belong to the group Illyrian-Adriatic endemic plants. Endangered taxa are Desmazeria marina (L.) Druce, Elymus pycnathus (Godr.) Melderis and Narcissus tazetta L. Strictly protected taxa include Chenopodium murale L. and Posidonia oceanica (L.) Delile. The invasive species Conyza canadensis (L.) Cronquist and Euphorbia prostrata Aiton have been recorded in the flora of the islet of Majsan.

kor乌拉群岛(亚得里亚海东南部)三个小岛的植物区系

2020年，对科尔丘拉群岛三个小岛的植物群进行了多次调查。共记录植物类群105个，其中被子植物101个，裸子植物3个，蕨类植物1个。胰岛的总植物群分布在48个科中。分类群数量最多的科是Poaceae（12.38%）和Asteraceae（10.48%），其次是Lamiaceae（7.62%）和Fabaceae（5.71%）。最常见的生命形式是兽生植物（31.43%）、半隐生植物（27.62%）和显生植物（19.05%）。植物分类群数量最大的是地中海花卉元素（60.95%），其次为南欧植物（20.00%），记录了3个特有类群、4个濒危类群和7个严格保护类群。地方病是Carduus microterus（Borbás）Teyber ssp。Microterus，Vincetoxicum hirundinaria Medik。ssp。adriaticum（Beck）Markgr和Limonium dictyophorum（Tausch）Degen。所有记录的特有分类群都属于伊利里亚-亚得里亚海特有植物群。濒危分类群为Desmazeria marina（L.）Druce、Elymus pycnathus（Godr.）Melderis和Narcissus tazetta L.。严格保护的分类群包括Chenopodium murale L.和Posidonia oceanica（L.）Delile。在Majsan岛的植物区系中记录了入侵物种加拿大稻（Conyza canadensis（L.）Cronquist）和匍匐大戟（Euphorbia prosta Aiton）。
