NVS code
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.

Simplified description
Ground hugging rosette herb in 1cm to several cm clumps. Lateral branched few to many, prostrate, up to 9cm long. Leaves oval to spoon-shaped; upper surface hairy except towards base, lower surface almost hairless. Leaf hairs stiff and spreading. Flowers white to cream, 3mm diameter.
Distribution
North Island south from the Coromandel Peninsula (a small islet near Coromandel Harbour), including Hawke’s Bay, Castlepoint, South Taranaki Coast and near Cape Palliser. South Island, south from Nelson, mainly east of main divide.
Habitat
Open coastal habitats to upland grassland, herbfield, open rocky, sandy places and stream sides. Sea level to 1200m a.s.l.
Similar taxa
Myosotis brevis. Myosotis pygmaea has larger flowers than Myosotis brevis.
Flowering
(August-) September to December (however sporadic flowering may occur throughout the year)
Flower colours
Cream, White
Fruiting
September to January (however fruits may be found throughout the year)
Propagation technique
Easily grown from fresh seed. However, plants are short-lived and prone to fungal diseases in humid climates.
Threats
The main threat throughout this species range is loss of habitat, caused by land development, weed invasion and coastal erosion.
Etymology
myosotis: Mouse-eared
antarctica: Antarctic
traillii: After Charles Trail, Stewart Islander
Where To Buy
Not commercially available.
Notes on taxonomy
The autonym Myosotis pygmaea var. pygmaea became unnecessary when de Lange & Barkla elevated the other varieties of M. pygmaea to species rank in de Lange et al. (2010).
