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.
Terrestrial. Lightly shaded frost-free areas, e.g. forest edges, shrublands, wetlands, streamsides, open forest, inshore and offshore islands, gumlands, slips, alluvial flats, coast and estuaries.
Erect, many-stemmed herb to subshrub to 1-2 m. Perennial fibrous rootstock. Stems often die back in winter, densely covered in stalked sticky hairs, usually purple, becoming woody, with branches in opposite pairs, often with galls formed by parasitic fly. Leaves in opposite pairs, 55-80 x 35-70 mm, diamond-shaped, margins irregularly roundtoothed. Flowers small, white, 5-7 mm diam, in dense terminal clusters, Aug-Dec. Seeds black, 5- angled, 1.8 mm long.
