| Summary: | The work describes the flora of higher sporeless vascular plants (superdivision Bryobionta, divisions Marhantiophyta, Bryophyta) and higher spore vascular plants (divisions Lycopodiophyta, Equisetophyta, Psilotophyta, Polypodiophyta) of Poltava region, analyzed the peculiarities of its systematic and taxonomic composition. As a result of research, it was established that the bryobiont flora includes 167 species, 87 genus, and 43 families. Lycopodiophyta – five species from four genus, two families, Equisetophyta – 9 species from one genus, one family, Psilotophyta – 2 species from 2 genus, 2 families, Polypodiophyta – 14 species from 11 genus, 7 families. The department Marchantiophyta is represented by 17 species from 11 genus, 9 families, Bryophyta – 150 species, 75 genus, 33 families. In general, according to the results of research, it was found that the flora of spore plants of the Poltava region includes 197 species from 104 genus, 55 families.It was established that there are 70 rare and endangered species in the studied flora (36.46% of the total number). Among bryophytes, there are 49 species (29.3% of the total number). One of them is Tortula randii (Kenn.) R.H. Zander – listed in the Red Book of Ukraine, Dicranum viride (Kenn.) R.H. Zander – in the European Red List, the rest – 47 species are regionally rare. Among the representatives of the division Lycopodiophyta, three species are listed in the Red Book of Ukraine (Diaphasiastrum complanatum (L.) Holub., Lycopodium annotinum L., Lycopodiella denudata (L.) Holub., Huperzia selago (L.) Bernh. ex Schrank et Mart.), one species, Lycopodium clavatum, is regionally rare. Among Equisetophyta, 4 species are included in the regional list, Psilotophyta – Botrychium lunaria (L.) Sw. – in the Red Book of Ukraine, Ophioglossum vulgatum L. – in the regional list, Polypodiophyta – Salvinia natans (L.) All., – in the Red Book of Ukraine, 10 species – to the regional list.
