Althenia bilocularis is a plant found in both Australia and New Zealand,^[3] in fresh to brackish waters. In Australia it is found in all mainland states with the exception of the Northern Territory.^[4] In New Zealand it is found on the North, South and Chatham Islands.^[5]

Taxonomy

It was first described as Lepilaena bilocularis by Thomas Kirk in 1896.^[1]^[6] It was transferred to the genus, Althenia , in 1927 by Leonard Cockayne.^[1]^[2] This change by Cockayne is supported by DNA analyses.^[7]
