Evolution of the Life Forms of Flowering Plants in a Biodiversity Formation

The biomorphological diversity of riverside and aquatic herbaceous plants represented mainly by annual and biennial plants of vegetative origin, which replace perennial and biennial plants and annual, biennial, and winter monocarpics, has been studied. Depending on the season and moisture conditions, some species are represented by different basic biomorphs and phenobiomorphs. The modes of morphological evolution have been determined at the levels of individuals (abbreviations), shoots and their parts (abbreviations and the corresponding prolongations), and roots (prolongations). The role of the developmental features of monocarpic shoots in the habitat specificity of annual and biennial plants of vegetative origin has been described.
