Detailed description
Prostrate to suberect, spreading woody shrub forming broadly domed patches up to 1.5 × 3.0 m. Trunk usually indistinct (mostly obscured by branches), slender, solitary (sometimes several arising from base). Branches numerous, spreading with slender trunk, branchlets densely leafy. Leaves bronze-green, dark green, sometimes dark wine-red or bronze-purple, closely spaced, spirally arranged, erect or sub-patent, rigid, coriaceous; lamina 5–15 × 2–4 mm, linear-oblong,± subulate, obtuse, apex ± apiculate, margins distinctly thickened, midvein prominent. Male strobili axillary, solitary or up to 4 per peduncle; peduncle 3–5 mm long, strobilus 5–15 mm long, apiculus obtuse. Female branchlet axillary, peduncle 3 mm. long, receptacle 2.5–10.0 mm long, red, elliptic-oblong to obovate-oblong, slightly compressed, smooth, swollen (fleshy). Seeds solitary or paired, 3·5–7·0 mm long, green when fresh, ovoid or ellipsoid-ovoid, weakly asymmetric, obtusely pointed.
Similar taxa
None. The prostrate or spreading suberect, heavily branched growth habit, densely leafy branchlets, and small, closely spaced, awl-shaped usually bronze-green leaves serve to distinguish this species from the other allied species of tōtara. Nevertheless where the ranges of Podocarpus nivalis overlap with that of Hall’s tōtara (P. laetus), tōtara (P. totara var. totara) and needle-leaved tōtara (P. acutifolius) hybrids can be common—these are chiefly distinguished by their suberect to erect growth habit, often pendulous branches and much longer, narrower leaves which are not distinctly awl-shaped. The hybrids are fully fertile and introgressive hybrid swarms are sometimes common, especially where the ranges of Hall’s tōtara and P. nivalis overlap. Podocarpus nivalis has also been confused with the Australian P. lawrencei which differs from P. nivalis in a range of characters but most notably by its consistently dark purple-brown coloured foliage.
Distribution
Endemic. New Zealand: North Island and South Island from Mt Hikurangi and Mt Pirongia south.
Habitat
Montane to alpine (virtually confined to subalpine and alpine areas in the North Island). Common in open tussock grassland, subalpine scrub and herbfield, at the base of active scree, amongst boulderfalls and on cliff faces and razorback ridges. Sometimes extending down into beech (Nothofagaceae forest) and down into valley heads.
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.
Please note, threat classifications are often suggested by authors when publications fall between NZTCS assessment periods – these interim threat classification statuses has not been assessed by the NZTCS panel.

Propagation technique
Easily grown from hardwood cuttings and fresh seed. Does well in full sun in a well drained, moist fertile soil. An excellent shrub for a rockery or small garden. A good subject for a tub garden or for making into bonsai. Despite its natural distribution Podocarpus nivalis is remarkably tolerant of drought and humidity.
