Abstract
<jats:p>The article is devoted to a comprehensive analysis of the evolutionary floral morphology of the family Asparagaceae s.l. within the framework of modern phylogenetic systems APG III and APG IV. The paper considers the radical transformation of the family's taxonomic structure resulting from the transition from classical morphological systems to molecular genetic models . The main focus is on the primary vectors of floral evolution: the emergence of syntepaly (tepal fusion), adnation of the androecium to the perianth, and the phenomenon of secondary epigyny. Based on W. Leinfellner's concept of vertical zonality, the internal architecture of the syncarpous gynoecium and the processes of ovule oligomerization in highly specialized taxa are analyzed . The diversity of septal nectary structures and the role of vascular anatomy as a reliable marker of phylogenetic divergence are highlighted separately. It is proved that the integration of classical micro-morphological data with the results of modern phylogenomic studies is a necessary condition for the verification of evolutionary relationships within the heterogeneous family Asparagaceae s.l..</jats:p>
