The National Vegetation Survey (NVS) Databank is a physical archive and electronic databank containing records of over 94,000 vegetation survey plots - including data from over 19,000 permanent plots. NVS maintains a standard set of species code abbreviations that correspond to standard scientific plant names from the Ngä Tipu o Aotearoa - New Zealand Plants database.

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.

Indigenous. New Zealand: South Island where it grows in high alpine situations mainly east of the divide, Chatham Islands, Auckland Islands and Campbell Island/Motu Ihupuku.
The mainland form grows in subalpine to alpine vegetation, typically in open rocky ground in fell field, herbfield, scree, rock outcrops, cliff faces or tussock grassland. Often found growing with Koeleria cheesemanii (Hack.) Petrie. The Chatham Island variant grows in dune swales. The subantarctic variant grows on peat and in rock crevices at sea level.

Easy from fresh seed and division of whole plants. Dislikes humidity, and does best in free draining, damp soils within a cool, airy site. Excellent in an alpine house. The typical form of this species will not flower at lower altitudes unless plants are subjected to 1–2 months cold treatment.
spicatum: Grows ears (like corn), in spikes

Notes on taxonomy
New Zealand T. spicatum is very variable. Plants from the subantarctic islands are very distinct from mainland New Zealand plants, as are those from the Chatham Islands. Further study into this variation is needed.
