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).
Features
Tall tree to 40 m with open-branching habit. The dark brown bark is fissured and forms scaly plates. The needles held in pairs and up to 19 cm long, are stiff, pointed, and grooved on the opposing sides of the pair. Male and female flowers arise in clusters on the branch tips in late spring. Mature female cones arise singly or in whorls of two to four, 8 by 3 cm.
Similar taxa
Long dark green needles held in pairs, small cones that are shed annually. No spikes on cone scales. Subsp. laricio has less dense foliage and more flexible leaves than subsp nigra, but the two subspecies can be difficult to distinguish.
Flower colours
No flowers
