Acorus Calamus L., Glycerya maxima (Hartmann) Holmberg, Menyanthes trifoliata L., Phalaris arundinacea L., Phragmites communis Trin. and Typha latifolia have lacunar Systems which allow efficient O2 transport from the surface air to the rhizomes. O2 is supplied mainly by transport through the shoot. The O2 content of the surroundings and, therefore, the O2 uptake through the surfaces of the rhizomes have no influence on the internal O2 concentration. When the rhizomes are detached the internal O2 concentration decreases to the limit of detection despite the air saturated environment. The rate of the O2 decrease is temperature and species dependent.
