Ruppia polycarpa
Ruppia polycarpa is a submerged aquatic herb that grows in shallow brackish water such as coastal lakes, lagoons and estuaries. It is a true aquatic plant, not a garden plant, so its key requirement is standing or flowing water with a suitable salinity.
Ruppia polycarpa is a submerged aquatic herb species in the genus Ruppia found in shallow brackish waters. It is a common submerged herb on Australasian coasts, including Australia (NSW; SA; Vic; WA) and New Zealand (type locality).
It was first described in 1967 by Ruth Mason from a specimen (CHR 150837B) found near the mouth of the Selwyn River, New Zealand, on the riverbed, on 27 February 1966 by J. Clarke.
