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.

Distribution
Endemic. From Clarence to Puhipuhi Rivers, South Marlborough.
Habitat
Coastal and inland lowland, usually confined to steep rocky or stony sites, rock faces and slopes.
Detailed description
Small and slender spreading shrub, less than 1m tall. Leaves diamond-shaped or blunt-ended 6.5-10cm long, 2.5-4cm wide, with a thin layer of felted hair on the back. Flower heads white, max. 3.5cm diameter. Flower stalks slender, sometimes leafy, about 10cm long.
Similar taxa
Pachystegia insignis. Leaves of P. minor are much smaller and more slender, with thinner layer of felted hair. It has smaller, slender stalked flowers, opening slightly later than other Pachystegia species.
Flowering
December to February
Flower colours
White, Yellow
Fruiting
February to April
Propagation technique
Easily grown from fresh seed but tricky to transplant. Can be grown from cuttings with extreme difficulty.
Threats
Pachystegia minor is probably very local in its distribution, and many of the more accessible populations are often damaged by browsing animals. Some populations are at risk from roads, fire and the spread of weeds such as gorse (Ulex europaeus).
Etymology
pachystegia: Thick covering
minor: Smaller
Where To Buy
Occasionally offered by retail plant and specialist native plant nurseries.
