Althenia is a genus of aquatic plants of the family Potamogetonaceae.[2] This has long been a group of two species in the Mediterranean Europe and South Africa, but in 2016 was revised to include an Australasian relative, Lepilaena.[3]

Species

Lepilaena

Lepilaena was a genus of aquatic and marine flowering plant comprising 6 or more species endemic[6][7] to coastal and brackish or alkaline inland waters of temperate Australia, Tasmania, and New Zealand.[5][6]

The species are appended with common names that derive from their description as water-mats; for example, L. australis is referred to as Austral water-mat and L. marina as Sea water-mat.

Interpretation of molecular evidence for this poorly studied genus suggests a close affinity with Zannichellia, another genus of aquatic plants.[5] Two species are noted for their occurrence in marine environs, L. cylindrocarpa and L. marina, in estuaries and tidal flats.[5] L. cylindrocarpa is also found in a variety of brackish inland waters of mainland Australia.[4] Other species may be found in habitats of fresh to brackish, still or slowly moving, coastal or inland waters.

Based on the molecular and morphological evidence, all the species been transferred to the genus Althenia in 2016.[8]
