Current conservation status
The threat classification 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. 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. Please note, threat classifications are often suggested by authors when publications fall between NZTCS assessment periods – a suggested threat classification status has not been assessed by the NZTCS panel.

Low growing sprawling shrub with fuzzy twigs bearing wrinkled oval smooth-edged leaves inhabiting sites in Northland. Often appears partly dead. Leaves 14-45mm long by 8-15mm wide, underside covered by whiteish fuzz. Flowers brownish, in small clusters along a leafless stalk. Fruit small, dry.
Endemic. New Zealand: North Island (Te Paki (Surville Cliffs) and near Whangarei (Mt Manaia, Mt Aubrey, Bream Head)
A plant of open, rocky ground, cliff faces and rock pillars. On the Surville Cliffs it is a common plant of open ultramafic (serpentinite) talus, cliff faces and less commonly plateau scrub. At Mt Manaia it is confined to the andesitic plugs and associated boulderfield
Rather untidy, prostrate, sprawling, often widely scrambling to sub-erect shrub 1-2 × 1-2 m, main branches arising at ground level, these often layering. Adult leaves 9-50 × 6-20 mm, oblong; upper surface glabrous; lower surface with dense tomentum of sessile and stalked stellate hairs, often brown or ferruginous; margins sinuate to shallowly crenate, not revolute; petioles to 10 mm, stipules 1-2 mm long, soon deciduous. Juvenile leaves extremely variable, sometimes < 6 mm long, conspicuously toothed, thinly tomentose on both surfaces. Inflorescence an axillary or terminal, elongated, leafless panicle. Flowers dark orange-brown or green-brown, c.4 mm diameter; calyx spreading, calyx-tube covered in mealy, stellate hairs, lobes c.1.5 mm long, persistent to capsule maturity. Petals 0. Anthers ovoid. Style divided to > ½ length. Ovary with apical tuft of short-rayed stellate hairs, wholly immersed in the calyx tube at anthesis, slightly > ½ immersed at fruiting. Fruit cocci opening by opercula occupying four-fifths of their inner faces. Seeds 1.6 × 1.1 mm, usually one per flower, dark brown, smooth, not glossy.
Easily recognised by the sprawling, widely spreading, growth habit (often with plants bearing many dead or dying branches), slender branches; stipules which are deciduous; glabrous adult leaves which have entire margins; and by the persistent sepals. It is perhaps closest to P. rugosa Cheeseman which differs by its geographic isolation (Herekino, Silverdale, Coromandel Peninsula, Hauraki Gulf Islands, Firth of Thames, Aotea and Kawhia Harbours), usually erect rather than sprawling, prostrate growth habit, cream or pale yellow, rather than brownish flowers and by the fruits which have deciduous rather than persistent sepals
October - December
November - February
Can be grown from layered pieces, semi-hardwood cuttings and fresh seed. Does best in full sun, with excellent drainage.
Aside from its localised distribution, this plant is abundant and under no obvious threat.

Where To Buy
occasionally available from specialist native plant nurseries
Other records of this species from Maunganui Bluff and Cape Maria Van Diemen are considered doubtful, and the latter location is not supported by wild herbarium specimens but only garden plants purported to be from that location.
Description based on herbarium specimens and both Allan (1961) and Webb et al. (1988).
