Background The proper identification of feather grasses in nature is often limited due to phenotypic variability and high morphological similarity between many species. Among plausible factors influencing this issue are hybridisation and introgression recently detected in the genus. Nonetheless, to date, only a bounded set of taxa have been investi...

Over the past two centuries, Altai krai, located in the southeastern part of Western Siberia, has undergone significant transformation as a result of the virgin lands development. The vast even territories of the krai, formerly occupied by steppes dominated by the feather grass, are now almost completely plowed up. Many types of steppe communities,...

The work presents original key, illustrations, notes on morphology and distribution extensions for 12 species of the genus Festuca in the Altai territory. The revision of the genus and the selection of material for illustrations was made on the basis of the herbariums ALTB, NSK, NS, TK, and the author's own collections.

The article analyzed main phytolith morphotypes produced and anatomical microscopic structure of grass leaf epidermis in dominant species in the south of West Siberia. Phytoliths are silica microfossils formed inside plant cells that allow identification of plants in paleobotanical studies. The choice of objects in the study was based on presence o...
