Marsilea cf. quadrifolia
It is unclear whether this is the correct species name for this plant, as it can be very difficult to determine Marsilea sp. However, this is another commendable Marsilea species for aquarium use that we offer at Florida Aquatic Nurseries. We use this name, until a better name is available, to differentiate it from the smaller M. hirsuta.
