Vascular – Native
Herbs - Dicotyledons other than Composites
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.

Inconspicuous sparse rosettes of long spikey leaves without stipules and with variable numbers of leaflets per leaf and with a sparsely leaved tall flower spike
Endemic. NW Nelson
Snow tussock herbfield 1400-1700 m
Slender tufted herb to 45 cm tall when in flower. Rosettes single or few. Leaves few, rather flaccid, 3-2 foliate or occ. reduced to a single leaflet (all forms may be present on a single plant). Sheath thin, pale, c. 80 mm long x 10 mm wide, tapering to apex; stipules absent or vestigial; petioles c. 7-8 cm long x 2 mm wide, keeled in lower part, flat in upper; internodes absent; primary pinnae 1 pair, approximate to terminal leaflet, flat, striate, margins finely serrulate-crenulate, c. 8 cm long x 2mm wide, abrubtly narrowing to pungent point; terminal leaflet to 10 cm long x 3 mm wide, sometimes with 1 short accessory pinnule. Flowering stem of male plants slender, ribbed, lower bracts sometimes without flowers; bract sheaths c. 3 cm long, thin, pale, tapering to a pair of narrow-linear, pungent, unequal stipules up to 5 mm long; bract lamina up to 7 cm long x 1 mm wide, pungent; umbels rather distant, on slender rays up to 2 cm long; umbellules several, c. 3 mm in diam., on filiform rays c. 2 mm long; flowers minute. Flowering stem of female plants similar but stouter, up to 10 mm diam.; bract sheaths firmer, furrowed, broader; stipules often reduced to one; bract lamina up to 10 cm long x 4 mm wide, midrib more evident, pungent; umbels more or less hidden by bracts, on short peduncles; umbellules few on short slender rays; fruit of two mericarps; mericarps (5.5-)6.0-8.5(-9.0), with 3-5 narrowly winged ribs, vittae sometimes obscured
Most similar to A. polita which has a more congested inflorescence
Winged schizocarps are dispersed primarily by wind (Thorsen et al., 2009).
aciphylla: From the Latin acicula ‘needle’ and the Greek phyllum ‘leaf’, meaning needle-leaf.
anomala: From the Greek anomalia ‘unusual’
