The article provides an analysis of life forms of 9 floristic complexes of the Ketpen ridge on the basis of many years of research materials, where life forms were studied in each floristic complex according to the systems of K. Raunkiaer and I.G. Serebryakov. An analysis of life forms according to the system of K. Raunkiaer established the dominance of hemicryptophytes in cryophilic-meadow (74.8%), petrophilic (72.5%) and deciduous-forest (80.3%) floristic complexes of the Ketpen ridge, which accounted for the total number of species of complexes. The second large group in terms of the number of species corresponded to cryptophytes, which predominate in the cryophilic-meadow (65.3%) and psammophilic (45.9%) floristic complexes. Distribution of species according to life forms according to I.G. Serebryakov demonstrated a clear predominance of polycarpic in the meadow complex amounting to 82.5%, deciduous-forest – 81.7%, psammophilous – 75.9% and steppe – 79.4% floristic complexes of the total number of species of complexes. An analysis of the meadow floristic complex of the Ketpen ridge according to Serebryakov showed that taproot plants account for 128 species or 20.5%, short-rhizome – 18.4%, long-rhizome – 11.3%, turf-rhizomatous – 4.8%. An analysis of the life forms of the psammophilic floristic complex revealed the prevalence of therophytes (40.7%). It was found that the spectrum of life forms according to Raunkiaer and Serebryakov emphasizes the peculiarities of the floristic complexes of the Ketpen ridge.

The article provides a comparative analysis of the flora and endemism of the western and eastern part of the KetpenTemerlik range in Kazakhstan and China, which is the eastern tip of the Northern Tian Shan. The flora of the entire Ketpen-Temerlik range includes 1890 species of vascular plants belonging to 593 genera and 120 families. In the western part of the ridge (in Kazakhstan), 1747 species were identified, belonging to 585 genera and 111 families and in the eastern part (in China), 1673 species belonging to 577 genera and 117 families. Angiosperms make up 98.4% of the ridge flora, 80.0% of which are dicotyledonous and 18.5% are monocotyledonous. The analysis of the largest flora families of the entire Ketpen-Temerlik range allowed us to identify 28 of the largest families by the largest number of species. The families with the largest number of species are Asteraceae (308 species), Poaceae (166), Fabaceae (133), Brassicaceae (105), Caryophyllaceae (93), Rosaceae (90), Lamiaceae (81), Chenopodiaceae (75), Ranunculaceae (74) and Scrophulariaceae (57). The major genera are Astragalus (43 species), Artemisia (38), Taraxacum (34), Carex (33), Allium (33), Potentilla (31), Ranunculus (22), Oxytropis (21), Veronica (20), Poa (18), and Saussurea (18).
