Biostatus

Native – Endemic taxon

Category

Structural class

Trees & Shrubs - Dicotyledons

Simplified description

Small dark green shrub inhabiting limestone in the north-western South Island

Flower colours

Brown, Green

Detailed description

?Dioecious shrub or small tree up to 5 x 5 m, crown broad, spreading, branches numerous arising from rootstock or from small, stout trunk up 0.3 m d.b.h.; branches initially ascending but soon spreading, sparingly branched toward main branch apices. Bark initially purplish-brown, fading to pale brown and maturing grey. All parts glabrous or arely glabrescent. Petioles stout 20-100 mm long, stipulately sheathing at base. Leaves 3-3(-5)-foliolate, petiolules 5-9 mm long; leaflets 30-80 x 15-25(-30) mm, dull dark green (darker above paler beneath), elliptic-oblong to ovate-oblong, narrowed to base, acute at apex, margin sharply serrated, veins indistinct above scarcely discernible below, midrib raised on both surfaces 1.5-2 mm wide. Umbels mostly terminal or near tips of subterminal branches, compound, seemingly unisexual; primary rays (3-)4-8, widely spreading, 30-60 mm long; secondary rays 6-15, 5-10 mm long, slender, umbellules 6-10-flowered, pedicels 1.5-4 mm long, slender. Staminate with slightly more rays than pistillate, dark green to brown-green, stamens 5-6, spreading; ovary 2-locular, styles 2, fused at base otherwise spreading. Fruit 3-6 mm diameter, broadly ovoid to orbicular or ellipsoid, longitudinally compressed, fleshy, purple-black when ripe.

Similar taxa

Could be confused with P. arboreus (Murray) Philipson and P. colensoi var. ternatus with which it sometimes grows. It differs from both by its restriction to calcareous substrates. From P. arboreus it differs by its much smaller stature, smaller leaves, narrower, consistently dark green, deeply serrated leaflets, fewer more gracile umbels that are more strictly terminal, fewer umbellules, smaller flowers and fruits. From P. colensoi var. ternatus it differs by its much smaller stature, much smaller leaves that are 3-5-foliolate rather than consistently 3-foliolate, narrower more deeply serrated leaflets, smaller umbels, umbellules, flowers and fruits.

Distribution

Endemic. South Island from north-west Nelson to just north of Greymouth

Habitat

Coastal to montane in shrubland and low, often successional forest overlying limestone, marble or dolomitic marble rock outcrops.

Current conservation status

The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2022-2023 using the New Zealand Threat Classification System (NZTCS) – more information about this can be found on the NZTCS website. This report includes replaces all previous NZTCS lists for vascular plants. Previous assessments can be found here.

Threats

At times a locally common component of coastal to montane karstfield, this species seems to be a naturally rather localised, usually biologically sparse western South Island endemic. There is no clear evidence that it has declined in any part of its range, and indeed because it is still poorly known it may even have a wider range than is currently recognised.
