Abstract
Objective — to study of the species diversity of epilithic bryophytes in Dendrological Park Olexandria.
Material and methods. The objects of the study were epilithic bryophytes of the historical part of Dendrological Park Olexandria. The commonly accepted methods of the floristic field investigations were used in this work. Latin names of the bryophytes were given according to the Checklist of the Bryobionta of Ukraine (2008; 2010). The short taxonomical analysis was conducted according to the recommendation of M.F. Boiko (2008).
Results. The epilithic bryophyte flora of the historical part of Dendrological Park Olexandria consists of 51 species. Marchantiophyta is represented by 5 species, 5 genera, 5 families, 4 orders and 2 classes, Bryophyta is represented by 46 species, 28 genera, 14 families, 5 orders and 1 class. The leading families are Brachytheciaceae (7 species), Pottiaceae (7), Amblystegiaceae (6), Bryaceae (5), Orthotrichaceae (4), Grimmiaceae (4) — 64.7 % of the total account. The leading genera are Bryum (5 species), Orthotrichum (4) and Grimmia (3 species).
Conclusions. The epilithic bryophyte flora of the historical part of Dendrological Park Olexandria consists of 51 species. Five taxa (Bryum ruderale Crundw. et Nyholm, Didymodon tophaceus (Brid.) Lisa, Pellia endiviifolia (Dicks.) Dumort., Porella platyphylla (L.) Pfeiff. and Syntrichia virescens (De Not.) Ochyra) are regional rare species in Forest-Steppe of Ukraine. The most of species (35), including 5 regional rare species, were found in the Eastern Beam and therefore it is necessary to ensure appropriate protection of these species in their habitats.
