An updated checklist of the vascular flora native to Italy

An updated inventory of the native vascular flora of Italy, providing details on the occurrence at regional level, is presented. The checklist includes 8195 taxa (6417 species and 1778 subspecies), distributed in 1092 genera and 152 families; 23 taxa are lycophytes, 108 ferns and fern allies, 30 gymnosperms and 8034 angiosperms. The taxa currently occurring in Italy are 7483, while 568 taxa have not been confirmed in recent times, 99 are doubtfully occurring in the country and 19 are data deficient. Out of the 568 not confirmed taxa, 26 are considered extinct or possibly extinct.本研究呈现了意大利本土维管植物区系（vascular flora）的更新版名录，其中包含各区域的物种分布细节。该名录共收录8195个分类单元（taxa），其中包括6417个物种与1778个亚种，隶属于1092个属和152个科；其中23个分类单元为石松类植物（lycophytes），108个为蕨类及其近缘类群（ferns and fern allies），30个为裸子植物（gymnosperms），8034个为被子植物（angiosperms）。目前在意大利有分布记录的分类单元共7483个，另有568个分类单元在近期未被确认存在，99个分类单元的分布存疑，19个分类单元的相关数据匮乏。在这568个未被确认的分类单元中，有26个被认定为已灭绝或可能已灭绝。
