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.

NVS Species Code

ELADEN

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.

Structural Class

Synonyms

Dicera dentata J.R.Forst. et G.Forst., Elaeocarpus hinau A.Cunn., Elaeocarpus cunninghamii Raoul

Distribution

Endemic. North, and South Islands

Habitat

Common tree of mainly coastal and lowland forest though occasionally extending into montane forest.

Features

Tree up to 20 m tall (usually less), with broad spreading crown. Trunk 1 m diam., bark grey. Branches erect then spreading, branchlets silky hairy when young. Petioles stout, 20-25 mm long. Leaves leathery, (50-)100-120 x 20-30 mm, narrow- to obovate-oblong, broad-obovate, oblanceolate, apex obtuse or abruptly acuminate, dark green and glabrescent above, off-white, silky-hairy below; margins somewhat sinuate, recurved, serrate to subentire. Inflorescence a raceme 100-180 mm long, 8-12(-20)-flowered. Pedicels 10 mm long, silky-hairy. Flowers drooping, (8-)12(-15) mm diam., sepals lanceolate-oblong, 6 mm long, petals white, obovate-cuneate, 3-5-lobed, c. 10 mm long. Stamens 10-20. Fruit a fleshy, ovoid purple-black 12-18 x 9 mm, drupe. Endocarp deeply furrowed and wrinkled.

Similar Taxa

A distinctive tree easily recognised by the erecto-patent leathery bicoloured leaves, white "lily of the valley" like flowers, and small ovoid purple-black drupes. Distinguished from the closely allied pokaka by the lack of a filiramulate, divaricating juvenile and sub adult growth form, and larger leaves, flowers and fruits. The status of Elaeocarpus dentatus var. obovatus Cheeseman accepted by the New Zealand Flora, but not by Druce (1993) needs further investigation. In its typical form this variety seems very distinctive, and pending further study it is retained here, especially as no one has undertaken a modern revision of New Zealand Elaeocarpus.

Flowering

October - February

Flower Colours

White

Fruiting

December - May(-June)

Propagation Technique

Easy from fresh fruit - though can be slow to germinate. Moderately easy in most soils, light and moisture regimes. However, does best in a deep, moist, well mulched soil.

Not Threatened.

Where To Buy

A beautiful tree which should be more widely grown. Makes an excellent specimen tree and should be more widely used in street plantings. Occasionally available from commercial and specialist native plant nurseries.
