    Detailed branching and morphometric characteristics of two Utricularia australis populations were compared at two sites in the Třeboň basin, Czech Republic. The sites, mesotrophic fishpond Ruda and oligotrophic sand-pit Cep, differed greatly in their trophic status and prey availability, and thus in plant size, fitness, and flowering. Flowering plants at Ruda were robust, highly branched, and produced on average totally 52 branches of various orders forming about 52.9 % dry weight of the total vegetative plant dry weight. In comparison, plants at Cep were much shorter, their internodes were strongly shortened, only 5 % of plants flowered, and only 60 % of plants bore distinguishable branches (on average only 1.1 branches a plant and 1.4 % of total plant dry weight). Shoot branching was recognized as one of the most important reasons for high plasticity of U. australis and for attaining high relative growth rate.
