Conservation status of New Zealand indigenous vascular plants, 2012
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2012 using the New Zealand Threat Classification System (NZTCS). This report includes a statistical summary and brief notes on changes since 2009 and replaces all previous NZTCS lists for vascular plants. Authors: Peter J. de Lange, Jeremy R. Rolfe, Paul D.

NVS Species Code

PODCUN

The National Vegetation Survey (NVS) Databank is a physical archive and electronic databank containing records of over 94,000 vegetation survey plots - including data from over 19,000 permanent plots. NVS maintains a standard set of species code abbreviations that correspond to standard scientific plant names from the Ngä Tipu o Aotearoa - New Zealand Plants database.

Structural Class

Gymnosperm Trees & Shrubs

Synonyms

Podocarpus hallii Kirk; Podocarpus cunninghamii Colenso

Distribution

Endemic. North, South and Stewart Islands.

Habitat

Lowland, montane to lower subalpine forest (but notable more common in montane forest).

Features

Robust dioecious conifer up to 20 m tall. Trunk stout, 1-1.5 m diam., clad in papery, thin, freely flaking reddish-grey bark. Trunk without branches at base, branches slender, erect, spreading or somewhat drooping. Leaf bud significantly broader than the diam., of the branchlet, surrounded by caducous, papery, ovate bracts. Leaves yellow-green, green, or brownish-green, erect, leathery; juvenile 25-50 x 4-5 mm, adults 20-30 x 3-4 mm., narrow-linear to linear-lanceolate, acute to acuminate, apex very pungent, mid-vein distinct. Male cones (strobili) axillary, 10-25 mm, solitary or up to 5 on a common peduncle. Female branchlets axillary, ovules solitary or paired. Receptacle of 2-4 scales, irregularly elliptic-oblong to obovate-oblong, maturing as a red, swollen, succulent, sweet tasting "fruit" this surmounted by a 1(-2) elliptic, elliptic-oblong or ovate-oblong, (5-)6.5-8.5 mm long, grey nut brown or dark brown (green when fresh) seed.

Similar Taxa

Distinguished from Podocarpus totara var. totara by the leaf bud which is wider than the diameter of the branchlet (resembles a meat ball on a stick), and by the broadly ovate bud bracts. The bark is generally papery - hence "thin barked totara", the leaves (especially juveniles and subadults) are longer and broader with a very sharp, pungent leaf tip. Hybridises with P. totara var. totara and hybrids can only reliably be distinguished by bud scale and bud diameter characters. See also Gardner (1990) in references below.

Flowering

(August-) October (-December)

Flower Colours

No Flowers

Fruiting

Fruits take a year or so to ripen, and may be found throughout the year, usually peaking at about the same time that cones are produced. They are most frequently seen between April and May

Propagation Technique

Easily grown from fresh seed and hard-wood cuttings.

Where To Buy

Uncommon in cultivation. Not often seen in gardens though it is commercially available.

Taxonomic Notes

Molloy (2015) has outlined the complex taxonomic history of Hall's totara noting that there are three valid names that could be used for this species, P. hallii Kirk, P. cunninghamii Colenso and P. laetus Hooibr. ex Endl. Molloy (2015) concludes that Podocarpus laetus is the earliest legitimate and validly published name, and in the absence of any final ruling on the matter that name is now used here. Previously it had been recommended that P. cunninghamii should be used (see Molloy 1985; de Lange & Rolfe 2010).
