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.

Current conservation status
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2017 using the New Zealand Threat Classification System (NZTCS). This report includes a statistical summary and brief notes on changes since 2012 and replaces all previous NZTCS lists for vascular plants. Authors: By Peter J. de Lange, Jeremy R. Rolfe, John W. Barkla, Shannel P. Courtney, Paul D. Champion, Leon R. Perrie, Sarah M. Beadel, Kerry A. Ford, Ilse Breitwieser, Ines Schönberger, Rowan Hindmarsh-Walls, Peter B. Heenan and Kate Ladley.

Hard shrub with thick wide-angled pale branches bearing often brownish small leathery leaves varying between smooth oval leaves and deeply-lobed leaves. Twigs with rusty or pale fuzz. Flowers dark red, inconspicuous. Fruit a capsule, surface uneven, splitting into two to show the 6-12 black seeds.
The characters used to distinguish Pittosporum crassicaule seem scarcely sufficient to separate this entity at species rank from the rather variable P. rigidum. Similarly the staus of larger-leaved forms known as var. majus is unclear. P. rigidum would repay critical study using a selection of molecular markers.
