Pleurozia
''Pleurozia'' is the only genus of Marchantiophyta, liverworts in the Family (biology), family Pleuroziaceae, which is now classified in its own order Pleuroziales, but was previously included in a broader circumscription of the Jungermanniales. The genus includes twelve species, and as a whole is both physically distinctive and widely distributed. The lower leaf lobes of ''Pleurozia'' species are fused, forming a closed water sac covered by a movable lid similar in structure to those of the angiosperm genus ''Utricularia''. These sacs were assumed to play a role in water storage, but a 2005 study on ''Pleurozia purpurea'' found that the sacs attract and trap ciliates, much in the same way as ''Utricularia''. Observations of plants ''in situ'' also revealed a large number of trapped prey within the sacs, suggesting that the species in this genus obtain some benefit from a carnivorous plant, carnivorous habit. After ''Colura'', this was the second report of zoophagy among the live ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
