Habitats, Plant Diversity, Morphology, Anatomy, and Molecular Phylogeny of (Popov) Akhani & Roalson.

(Popov) Akhani & Roalson is listed in the Red Data Book of Kazakhstan as a rare species with a limited distribution, occurring in small populations in Kazakhstan, Uzbekistan, and Turkmenistan. The aim of this study is to deepen the understanding of the ecological conditions of its habitats, the floristic composition of its associated plant communities, the species' morphological and anatomical characteristics, and its molecular phylogeny, as well as to identify the main threats to its survival. The ecological conditions of the habitats include coastal sandy plains and the slopes of chinks and denudation plains with gray-brown desert soils and bozyngens on the Mangyshlak Peninsula and the Ustyurt Plateau at altitudes ranging from -3 to 270 m above sea level.
