A detailed 14-d growth experiment on two temperate aquatic Utricularia species with dimorphic shoots, U. stygia and U. intermedia, was conducted at two natural shallow dystrophic sites in S Bohemia, Czech Republic. Both sites were oligo- to slightly mesotrophic, and dissolved O2 and free CO2 concentrations were sufficient so as not to limit plant growth. Both species exhibited a similarly high apical growth rate of photosynthetic shoots (1.9-2.1 leaf node d-1), as is reported in the literature for aquatic Utricularia species with monomorpic shoots. Moreover, the estimated doubling time for biomass of the two species (6.6-9.2 d) represents the absolute maximum growth rate ever estimated for an aquatic carnivorous plant (Aldrovanda, Utricularia spp).
