Conservation status of New Zealand indigenous vascular plants, 2012
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2012 using the New Zealand Threat Classification System (NZTCS). This report includes a statistical summary and brief notes on changes since 2009 and replaces all previous NZTCS lists for vascular plants. Authors: Peter J. de Lange, Jeremy R. Rolfe, Paul D.

Damp seepages on cliff faces, stream banks and collected also from alpine flushes

Threats

Unknown. At one stage believed to be highly threatened as the then only known populations occurred in highly vulnerable sites along roadsides.near Reefton. because the species was poorly understood it was re-assessed as "Data Deficient" "OL" [One Location] and "?SO" [Secure Overseas] (Glenny et al. 2011). Since then Paraphymatoceros hirticalyx has been recognised in the North Island from Little Barrier (Hauturu) Island and Mt Ruapehu suggesting that it is more overlooked than it is truly threatened. Further survey to clarify its true threat status in New Zealand would be useful.
