Within its range, this plant occurs in areas with moist, stable soils such as in hollows in tussocklands and the floors of ravines. It can be distinguished from its closest congeners by the purple or dull green (rather than bright green) foliage and the sessile fruits which are often hidden among the leaves rather than being borne above. Flowering occurs in December and January with fruit being produced in February.[2]

This species has the "Nationally Critical" conservation status under the New Zealand Threat Classification System.[3]
