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). This report includes a statistical summary and brief notes on changes since 2012 and replaces all previous NZTCS lists for vascular plants. Authors: By Peter J. de Lange, Jeremy R. Rolfe, John W.

Endemic. New Zealand: North Island (Kuripapango), South Island (Nelson - Southland except Marlborough and Westland)
A species growing on the margins of lakes and tarns and other wet depressions and seepages in drought-prone and dry-climate areas of inland South Island
Herbs, perennial, rhizomatous, glabrous. Stems usually
Distinguished from Hypericum pusillum by the rhizomatous growth habit, leaves that are grey-green to olive-green and usually ruddy and without sinuate margins, slightly larger flowers, and seeds with distinct longitudinal ridges
Seeds are wind and water dispersed (Thorsen et al., 2009).
Easy. Best grown in a small pot kept partially submerged in water. An attractive plant on account of the grey-green, reddish leaves and bright yellow flowers.
Although confined to a very specific habitat, at present there is no evidence to suggest that this species is threatened. However, the habitat that it occupies is under considerable pressure throughout much of its range because of water abstraction for dairy farms and residential developments. This species may prove to be threatened in the next few years. More survey and monitoring of known populations is needed. Previously regarded (as Hypericum aff, japonicum (b) (CHR 140620; “tarn”)) as Range Restricted in de Lange et al., 2004, Threatened and uncommon plants of New Zealand, New Zealand Journal of Botany 42: 45-76.
hypericum: From the Greek hyper (above) and eikon (picture), the plant was hung above pictures to ward off evil spirits
