Current conservation status
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2017 using the New Zealand Threat Classification System (NZTCS) – more information about this can be found on the NZTCS website. This report includes a statistical summary and brief notes on changes since 2012 and replaces all previous NZTCS lists for vascular plants.
Please note, threat classifications are often suggested by authors when publications fall between NZTCS assessment periods – an interim threat classification status has not been assessed by the NZTCS panel.

Endemic. North and South Islands - but uncommon in the South Island and found there mainly in the north.
Wetland plant indicator status rating
Commonly occurs as either a hydrophyte or non-hydrophyte (non-wetlands).
Mericarps are dispersed by water and wind (Thorsen et al., 2009).
hydrocotyle: From the Greek hydor ‘water’ and cotyle ‘cup’, in reference to the cup-like hollow at the base if the leaf.

Notes on taxonomy
Often found growing symaptric with H. moschata var. moschata and it should perhaps be regarded as a distinct species. The status of Hydrocotyle laciniata Kirk in relation to this variety needs further study.
