Detailed description
Robust dioecious conifer up to 20 m tall. Trunk stout, 1–1.5 m diameter, clad in papery, thin, freely flaking reddish-grey bark, without branches at base. Branches slender, erect, spreading or somewhat drooping. Leaf bud significantly broader than the diameter, of the branchlet, surrounded by caducous, papery, ovate bracts. Leaves yellow-green, green, or brownish-green, erect, leathery; juvenile 25–50 × 4–5 mm, adults 20–30 × 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.
Distribution
Endemic. North Island, South Island and Stewart Island/Rakiura.
Habitat
Lowland, montane to lower subalpine forest (but notably more common in montane forest). Often found on impoverished soils, immature (skeletal) soils, or sites that are naturally stressed by drought or extreme temperature fluctuations.
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.

Taxonomic notes
Molloy (2015) has outlined the complex taxonomic history of Hall’s tōtara 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).

Ecology
Flowering
(August)–October–(December)
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.
Wetland plant indicator status rating
Information derived from the revised national wetland plant list prepared to assist councils in delineating and monitoring wetlands (Clarkson et al., 2021 Manaaki Whenua – Landcare Research Contract Report LC3975 for Hawke’s Bay Regional Council). The national plant list categorises plants by the extent to which they are found in wetlands and not ‘drylands’. The indicator status ratings are OBL (obligate wetland), FACW (facultative wetland), FAC (facultative), FACU (facultative upland), and UPL (obligate upland).

FACU: Facultative Upland
Occasionally is a hydrophyte but usually occurs in uplands (non-wetlands).
Other information
Cultivation
Uncommon in cultivation. Not often seen in gardens though it is commercially available.
Etymology
podocarpus: Foot or stalk fruit
laetus: From the Latin laetus ‘bright’
