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). This report includes a statistical summary and brief notes on changes since 2012 and replaces all previous NZTCS lists for vascular plants. Authors: By Peter J. de Lange, Jeremy R. Rolfe, John W. Barkla, Shannel P. Courtney, Paul D. Champion, Leon R. Perrie, Sarah M. Beadel, Kerry A. Ford, Ilse Breitwieser, Ines Schönberger, Rowan Hindmarsh-Walls, Peter B. Heenan and Kate Ladley.

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.
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.
Open coastal habitats to upland grassland, herbfield, open rocky, sandy places and stream sides. Sea level to 1200m altitude.
Myosotis brevis. Myosotis pygmaea has larger flowers than Myosotis brevis.
(August-) September to December (however sporadic flowering may occur throughout the year)
September to January (however fruits may be found throughout the year)
Easily grown from fresh seed. However, plants are short-lived and prone to fungal diseases in humid climates.
The main threat throughout this species range is loss of habitat, caused by land development, weed invasion and coastal erosion.
Where To Buy

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).
