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.

bushy shrub with large hand-shaped leaves on red stalks
Endemic to the northern part of the North Island from Coromandel to inland Gisborne and Taranaki.
Small multi-branched tree to 5 m tall, branchlets brittle. Leaves alternate, leaflets 5-7, palmate, on short petiolules. Petiole to 25 cm long, sheathing branchlet at base, stipules present, purplish red. Petiolules stout, purplish red or leaflets subsessile. Leaflets obovate- to cuneate-oblong, thick and coriaceous, green above, paler below, margin coarsely dentate-serrate in distal half, acute or acuminate to subacute; midveins and main lateral veins obvious above and below; teminal lamina 12-25 x 5-10 cm or more, lateral leaflets smaller. Inflorescence a terminal, compound umbel, flowers sometimes subracemose on secondary rays; primary rays (branchlets) 10-15; 15-20 secondary rays. Calyx truncate or obscurely 5-toothed; petals ovate-oblong, acute. Ovary 2-loculed, each containing 1 ovules; style branches 2, spreading. Fruit fleshy, purple, c. 5 mm diam., laterally compressed, style branches retained on an apical disc. 2 Seeds per fruit, broadly-ovate or oblong, wrinkled, 3.4-4.7(-5.1) mm long.
The dark red petioles and large leaflets of this species are distinctive
(August)-September to November
October to February
Very easy from fresh seed. Can be grown from semi-hardwood cuttings. Very fast growing and tolerant of a wide range of soil types and moisture regimes but dislikes very dry soils. Best in damp soils.
This species is highly palatable to browsing animals. Subsequently it is usually only found in cliff refugia or other similar sites inaccessible to browsing animals. Possums seriously damage plants and have been responsible for its near extinction in some parts.
pseudopanax: False cure
laetus: From the Latin laetus ‘bright’
Where To Buy
Common in cultivation and sold by most plant nurseries.
