Abstract
The unique features of embryo development, morphological and anatomical shoot structure, and the root system in one of the smallest annual plants mousetail at the earliest and following stages of ontogenesis are shown. The correspondence of revealed structures (presence of collet with rhizoids, aerenchyma in the primary cortex of the hypocotyl and adventive roots, secondary homorhizia, plane apical meristem together with obligate rozett structure of the main shoot) and of polyvariant ontogenesis (spring ephemeral variant and variant with overwintering) and longevity of life circle phases to the ecological features of the species—hygrophyly, minimal threshold size (minimal number of metamers of the main shoot axis)—are discussed.
