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.

Taxonomic notes
The decision by Conn (1987) to treat the Geniostoma ligustrifolium as a variety of G. rupestre J.R.Forst. et G.Forst. does not accurately reflect the situation in this country. G. ligustrifolium var. ligustrifolium is sympatric with var. crassum (also treated as G. rupestre var. crassum by Conn in Connor & Edgar (1987)) on the Surville Cliffs and with var. majus (treated by Conn (1980) as a synonym of G. rupestre var. ligustrifolium) on the Three Kings Islands. In these locations occasional hybrids occur but otherwise the three taxa remain distinct (see Murray & de Lange 1999). Therefore the NZPCN follow Murray & de Lange (1999) and prefer to regard all three taxa as distinct from each other and G. rupestre.

Ecology
Life cycle and dispersal
Seeds are dispersed by frugivory (Thorsen et al., 2009).
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).

Etymology
geniostoma: The tribe with pitted seed
ligustrifolium: From the genus Ligustrum privet and the Greek word phylum ‘leaf’, meaning privet-leaved
