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.

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.
Dicotyledonous Trees & Shrubs
Trichilla spectabilis G.Forst., Hartighsea spectabilis Juss.
Endemic. North and South Islands. In the South Island not extending much beyond the Marlborough Sounds, reaching a southern limit near the Hurunui River (Napenape).
Common and sometimes dominant or co-dominant tree of coastal to lowland forest.
Tree up to 15 m tall usually with abroad, spreading canopy. Trunk up to 1 m diam., branches stout, erect then spreading. Bark pale brown, under bark green. Leaves compound, imparipinnate, alternate on pulvinate petioles up to 40 mm long, leaflet pairs 4-6, (50-)-150(-200) x (20-)30(-80) mm, opposite to subopposite, bright green, yellow-green to dark green, ovate to obovate-oblong, leathery, margins somewhat undulate. Plants gynodioecious, with fixed female and inconstant males on different trees. Inflorescence a cymose, drooping, panicle arising from trunk and branches (cauliflorous). Flowers c. 30 mm diam., fleshy. Pedicels short. Calyx divided to base, lobes broad-oblong, abruptly pointed, ciliate, petals linear, 10 mm, spreading, waxy white or greenish. Capsules, woody, broad-obovoid to subglobose, 3-4-celled, c. 25 mm long, green. Seeds 2 per cell, orange or scarlet.
A very distinctive tree which with its large compound green leaves and cauliflorous flowering habit could not easily be confused with any other indigenous, naturalised or exotic species present in New Zealand.

Easy from fresh seed.
Not Threatened. However, where possum and rat numbers are high this species is not actively regenerating. Possums defoliolate trees, and will heavily browse inflorescences such that few succeed in flowering and setting fruit. Rats are major seed predators. Only where control of these animals is undertaken, or on possum and rodent-free offshore islands can one see kohekohe flowering, fruiting and regenerating freely. If numbers of these introduced animals remain unchecked, it is clear that kohekohe will decline and vanish from large parts of its natural range.

Life Cycle and Dispersal
Arillate seeds are dispersed by frugivory (Thorsen et al., 2009).
Easily grown in a variety of situations and moisture levels. Intolerant of cold, and frost-sensitive.
