THE occurrence of vesicular−arbuscular (VA) mycorrhiza in flowering plants is a common phenomenon. Harley¹ pointed out that it is easier to list the few plants from which the endophyte is normally absent. It has been stated that aquatic plants are not infected by VA mycorrhiza^1,2. Read et al. ³ found infection levels to be low and often absent in marsh plants and infection in Cladium spp. occurred only during dry periods⁴. During an investigation of root hair development in Littorella uniflora, Lobelia dortmanna, and Isoetes lacustris VA mycorrhiza was discovered in connection with evaluation of root uptake of inorganic carbon and nutrients⁵. Other submerged and a few emergent aquatic plants were also investigated.
