The article examines the life forms of 14 species of the genus Hedysarum belonging to two sections (Obscura and Multicaulia) distributed in Central Asia, including the Central and Western Tien Shan (Talas, Fergana, and Alay ranges), Pamir-Alai and Kopet Dag. The morphological features of mature plants, branching types and a comparative analysis of the characteristics of the studied species—particularly those from the Obscura section (species H. flavescens and H. denticulatum)—were studied. Samples were collected from various types of habitats: grassy, rocky-shallow slopes, red clay outcrops, woody-shrubby thickets, archaea, spruce forests, subalpine meadows, and glacial belts. The life forms of the species were identified: H. severzovii and H. pumilum are classified as low-growing, sparsely branched shrubs with a bushy form; H. micropterum and H. wrightianum are classified as short-lived semi-shrubs, transitional from perennial herbaceous plants to short-lived shrubs; H. cephalotes is classified as a perennial turfgrass. The remaining species are perennial herbaceous plants with varying lifespans.
