The taxonomy of Mosquitoferns (Azolla spp.) is in a state of uncertainty. The species found in Maryland has historically been called Azolla caroliniana. However, a study by Evrard & Van Hove (2004. Syst. & Geogr. Pl. 74: 301–318) found that the name Azolla cristata Kaulf. is better applied to this species. Few subsequent authors have followed this treatment and the name Azolla caroliniana is still widely used. In addition, most specimens (and all field photos) of Azolla lack the characteristics necessary for confident identification. Although only one species has been reported from Maryland, detection of other species is unlikely without intentional and careful investigation.
Carolina Mosquitofern can be found floating on the surface of freshwater ponds and wetlands. It can often be found at the margins of lakes mixed with duckweeds.
Has a symbiotic relationship with Mosquito Fern Cyanobacterium.
