Abstract
The typological problem of revealing architectural models of annual astragali ( Astragalus L.) has emerged a close relationship between the shoot system and the structure of inflorescences. The features of the selected four patterns of architectural models are discussed. The synthesis of approaches has given us insight into the evolutionary trends. The application of the method of architectural models provide the means of classifying of life forms of annual astragali. The synthesis of molecular data, taxonomy and biomorphology confirms the concept of mosaic evolution and heterochronism (heterobatmy) of characters.
