Similar taxa
In the field this species has a similar appearance to a Rytidosperma, but there is only one floret per spikelet. The obvious hairs around the floret and the awn projecting beyond the glumes distinguish D. aucklandica from other species of Deyeuxia.
Distribution
Endemic. North, South and Stewart Islands, from Mt Pureora south.
Current conservation status
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2022-2023 using the New Zealand Threat Classification System (NZTCS) – more information about this can be found on the NZTCS website. This report includes replaces all previous NZTCS lists for vascular plants. Previous assessments can be found here.
Please note, threat classifications are often suggested by authors when publications fall between NZTCS assessment periods – these interim threat classification statuses has not been assessed by the NZTCS panel.
