Since there is a debate among scientists about the feasibility of combining these subfamilies into one family or the separation of distinct families: Agapanthaceae, Alliaceae, Amaryllidaceae, which are well distinguished by phenotypic characteristics, it is important to study the flower and fruit to confirm or deny the need to integrate the studied taxa. Particular attention is paid to the study of anatomical features of the flower and fruit, micromorphology and vascular anatomy of the flower, the study of fruit histogenesis and the application of these features in the phylogenetic analysis of the family. The structural features of the flower in 33 species from 15 genera belonging to 10 of 15 tribes and the characteristics of the fruit in 24 species from 16 genera of all three subfamilies of the family Amaryllidaceae were studied by light microscopy on permanent preparations of the cross and longitudinal sections. According to the results of a cladistic analysis of 33 studied species from 15 genera on 22 studied features of micromorphology and anatomy of the flower, the division of the family Amaryllidaceae into three monophyletic groups corresponding to subfamilies was confirmed, as well as monophyly of tribes Galantheae and Narcisseae. Based on the comparative morphological studies of flowers and fruits, we concluded that it is inexpedient to unite families that are well differentiated by a set of structural features, and we proposed to distinguish three separate families: Agapanthaceae, Alliaceae, Amaryllidaceae.
