Аннотация: Introduction. Although in all proven cases of carnivory in plants the relevant species are in theAngiospermae, it has been posited that this phenomenon occurs in two genera of liverworts,Colura and Pleurozia. The suggested occurence of zoophagy in these groups is largely basedon their trap-like water sacs, leaf modifications, and the positive results of ‘feeding’experiments; however, no evidence of nitrogen uptake has been presented.Methods. We measured δ13C, δ15N, %С and %N in Pleurozia acinosa (Mitt.) Trevis. from tropicalmontane forests in Vietnam, and in representatives from several reference plant groups, bothcarnivorous and non-carnivorous, and including epiphytes and terrestrial plants.Key results and conclusions. δ13C values in Pleurozia acinosa were significantly higher than inall other groups of plants studied. However, δ15N was significantly lower in P. acinosa than inboth groups of true carnivorous plants, and it did not differ from that in non-carnivorousvascular epiphytes and phorophyte trees, being even lower than in other epiphyticbryophytes. Thus, our results do not support the suggestion of carnivory in the genus Pleurozia
