The current article presents the results of the study made on Adonis vernalis L. coenoflora of Northern Kazakhstan. The materials have been obtained in the course of field research considering the literary data. The list of Adonis vernalis L. flora discovered in Northern Kazakhstan is based on detailed route studies. The coenoflora of Adonis vernalis L. in Northern Kazakhstan includes 140 species belonging to 31 families and 96 genera. The leading families are Artemisia, Veronica, Achillea, Galatella, Lathyrus, Potentilla, Seseli, Silene. The majority of species belongs to perennial species, annuals and biennials are represented by six species, and there is only one ephemeral species. Woody and semi-woody plants are represented by three trees, five shrubs and one semishrub. Among the herbaceous plants there are more long-rooted and stem-rooted species. The coenoflora mainly consists of mesophytes (68 species) and xeromesophytes (57 species). There are 15 species of xerophytes, which makes 10,7%. A little number of xerophytes proves meadow and meadow-steppe nature of the coenoflora.

The article provides the study results on the age-related stages of Pulsatilla multifida Mill. The materials have been gathered in the course of field research taking into account the literary data. The studies were carried out in the Pavlodar and Akmola regions during the season of mass flowering and seeds ripening (2018-2019). A rosette shoot is formed on the stage of seedlings out of 3-4 leaves of different complexity. On the juvenile stage the rosette shoot is formed out of 4-5(6) leaves. The leaves are tripartite, dissected into large lobes and in their turn are cut into prongs. The root system is represented by a stem-root and many roots of the second order. Immature individuals undergo the formation of an elongated rhizome. Leaf-blades are tripartite with deeply dissected lobes. 1-3 rosette shoots grow from resumption buds. The calendar age of an immature plant is 1-2 years. On the virginal stage, there is an increase of resumption buds and rosette modules, the formation of a powerful rhizome with numerous resumption buds on it. Leaves acquire a specificity: the number of prongs on the leaves becomes narrow, middle leaves develop a petiole of different lengths. Young generative plants have 1-3 peduncles and 1-3 rosette shoots. On average generative stage, the rhizome forms a many-headed caudex with numerous rosette shoots. In old age the number of rosette shoots decreases, the peduncles remain underdeveloped and do not start blooming. The leaves are cut into very narrow lobes with a large number of prongs, while the length of the petiole at the central lobe becomes minimal. In subsenile plants, there is a maceration of rhizomes to a greater depth with the formation of vegetative rosettes on separate parcels and they are represented by a system of dying rhizomes, with single vegetative sockets. The coenopopulations of P. multifida and P. aggr. patens are found in rocky habitats, except CP-1 (a glade between the rocks) where P. multifida grows on a dry meadow among steppe shrubs. All the studied populations are generative, the density of species is high enough to ensure the normal existence of the species in natural conditions.

The article presents the study results made on the Adonis wolgensis coenopopulation in Northern Kazakhstan (2018–2019). The materials have been gathered in the course of field research taking into account the literary data. The age structure of the coenopopulations is provided on the basis of detailed route studies. There have been studied eight coenopopulations located in Akmola, Pavlodar, and Kostanay regions. A. wolgensis is a short-stem herbaceous polycarpic of Northern Kazakhstan. A. wolgensis coenopopulations are found in three main habitats: steppe, meadow-steppe, and forest communities. The study of A. wolgensis coenopopulations in the latitudinal direction from Ekibastuz in the east to the Kostanay region in the west has revealed a high recovery index in steppe ecotopes. In other coenopopulations it is less than one. It is especially low in forest habitats. Most coenopopulations have a normal character according to the spectrum of age conditions, and they are maturing. This fact proves no negative impact of environmental and anthropogenic factors on the structure of coenopopulations and ensures their recovery and preservation.
