Abstract

Results of floristic investigation in the territory of the Forest-Steppe zone of Zhytomyr Region (Oblast) conducted in 2022 are reported. As a result of the work, it was revealed 11 new plant species for Zhytomyr Region (Alyssum desertorum, Bothriochloa ischaemum, Bromus commutatus, Eremogone procera, Euphorbia stepposa, Festuca rupicola, Fumaria parviflora, Ranunculus rionii, Symphytum caucasicum, Taraxacum serotinum, and Verbascum chaixii subsp. orientale). Also, 11 plant species new for the Forest-Steppe zone of Zhytomyr Region were found, and new localities of 14 rather rare plant species are reported. Their locations are briefly described, and, for the majority of species, phytogeographical comments are provided. Among native species, five are regionally rare in Zhytomyr Region (Anemone sylvestris, Carex humilis, Linum perenne, Phlomoides tuberosa, and Salvia nutans). In addition, highly active plants have been revealed among new alien species, such as Symphytum caucasicum; they require further monitoring. It has been suggested that an important role in migrations of steppe plant species in the region played valley of the Rostavytsia River, a tributary of the Ros’ River, and the system of ancient valleys which forms a common hydrographic network with them.

日托米尔地区森林草原区系的新发现。报告二世

报告了2022年在日托米尔州森林草原带境内进行的植物区系调查结果。结果表明，该地区共发现了11个植物新种(荒漠苜蓿、木犀草、折枝草、毛蕊草、大戟草、羊蹄草、细枝草、毛茛、高加索共生、蒲公英、柴草亚种)。东方)。此外，还发现了日托米尔地区森林草原带的11种植物新种，报道了14种较为罕见的植物新址。简要描述了它们的位置，并对大多数物种提供了植物地理学评论。在本地物种中，有5种是本区罕见的，分别是银莲花(Anemone sylvestris)、毛蕊草(Carex humilis)、二年生亚麻(Linum perenne)、桔梗(Phlomoides tuberosa)和鼠尾草(Salvia nutans)。此外，在新的外来种中还发现了高活性植物，如Symphytum caucasicum;它们需要进一步监测。研究认为，罗斯塔维察河的支流罗斯塔维察河流域和与之形成共同水系的古河谷系统对该地区草原植物物种的迁移起了重要作用。
