Pseudopanax colensoi var. colensoi is a subalpine native evergreen shrub or small canopy tree with spreading branches growing to a maximum height of 5m. It grows from the Central North Island and Coromandel Range south to the Banks Peninsula on South Island east coast. Plants with sessile leaflets from the Fiordland-Stewart Island area are often referred to Pseudopanax colensoi var. fiordensis. It is apparently absent from South Island West Coast. On Mt Taranaki/Mt Egmont it grows up to 1200m in montane forest scrub and lower subalpine scrub.
It has 3-7 fleshy leaflets (50-200 mm x 20-110 mm) arranged fanwise on very short stems (50-200 mm long). Leaves have serrated margins. 
In October-March it produces cream/green, heavy-scented flowers and then small (4-6 mm) black compressed fruit on large sprays below the leaves.
This shrub is heavily predated on by possums. 
There are two other subspecies of  Psuedopandex colensoi  They are  Psuedopandex colensoi var. ternatus and  Psuedopandex colensoi var. fiordensis.
