		Along with Filicales, Marsileales and Salviniales are considered to be leptosponrangiate ferns.
		Marsileales and Salviniales both have derived attributes of heterospory and endosporic gametophyte development.
		Marsileales consist of 3 genera: Marsilea, Regnellidium, and Pilularia.

	Marsileales - Wikipedia, the free encyclopedia
		The order Marsileales was formerly known as the Hydropteridales, but by modern rules of botanic nomenclature the name has been changed.
		Formerly the species in this order were all placed in the same family for fairly superficial reasons of heterosporosity and aquatic habitat, but modern analysis has borne out their relationship.
		There is a well-known fossil member of the Marsileales, Hydropteris (incertae sedis).

	FERN.6
		The Marsileales are comprised of three genera, Marsilea, Regnellidium and Pilularia.
		The reproductive structures of the Marsileales are called sporocarps: these are small bean-like structures borne singly or on branches at the base of fronds, and are produced during adverse conditions, as water availability becomes scarce.
		Salvinea has a rhizome that bears leaves in whorls of three, with two of each whorl being thick, flattened photosynthetic leaves that have a thick pad of hairs on their abaxial surface that maintain them as floating plants, and a third leaf that is highly dissected, submerged and acts as a root.
