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.

Current conservation status
The threat classification 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) – more information about this can be found on the NZTCS website 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. Barkla, Shannel P. Courtney, Paul D. Champion, Leon R. Perrie, Sarah M. Beadel, Kerry A. Ford, Ilse Breitwieser, Ines Schönberger, Rowan Hindmarsh-Walls, Peter B. Heenan and Kate Ladley. Please note, threat classifications are often suggested by authors when publications fall between NZTCS assessment periods – a suggested threat classification status has not been assessed by the NZTCS panel.

Endemic. Three Kings, North, South, Stewart and Chatham Islands.
Coastal to subalpine (1-1100 m a.s.l.) but mainly found in the coastal, lowland and lower montane zone. Favouring dry situations on rock outcrops, cliff faces, clay banks or similar semi-shaded to sunny habitats. Often under seral vegetation or under relatively open Kunzea ericoides (A.Rich.) Joy Thomps. s.l. dominated vegetation.
Erect sparingly branched (up to 4 branches), slender perennial herb 150-700 mm tall; entire plant densely covered with erect glandular and eglandular hairs, the stems completely pubescent. Petiole 2-18 mm long, winged. Leaves opposite except in and near inflorescence where alternate; lateral veins prominent, 3-4 on each side of midrib; lamina 7-43 x 4-24 mm, dull green, narrowly obovate to broadly ovate, apex subacute to obtuse, base attentuate to rounded; margins serrulate, bearing 8-32 teeth. Inflorescence and flowers nodding. Pedicels 1-3 mm long. Ovaries 10-27 mm long, densely pubescent, with a fine covering of erect eglandular and glandular hairs. Floral tube 0.7-1.0 x 1.5-2.0 mm, internally glabrous or furnished with a few sparse hairs. Sepals 2.5-2.8 x 1.0-1.1 mm, not keeled, densely pubescent with mixtures of erect glandular/eglandular hairs. Petals 3.5-7.0 x 2.9-4.0 mm, white, notch 0.6-2.0 mm deep. Anthers 0.7-0.9 x 0.5-0.6 mm, yellow; filaments white, those of longer stamens 1.7-2.7 mm, shorter 0.8-1.2 mm. Style 2.0-2.8 mm, white, glabrous; stigma 1.5-2.6 x 0.6-0.8 mm, white, clavate. Capsule 2.9-5.3 mm long, densely covered with erect glandular and eglandular hairs; pedicel elongating to 15 mm long. Seeds 0.75-0.92 x 0.35-0.42 mm, dark brown, obovoid, papillose, coma 4-5 mm, detaching readily.
Allied to Epilobium astonii (Allan) Raven et Engelhorn from which it differs by its slender scarcely branched, rather than much larger, compact, bushy, growth habit; shorter sepals (2.5-2.8 cf. 5.0-6.5 mm) and petals (3.5-7.0 cf. 7.3-13.0 mm); and by being a much more widespread species, occupying varied substrates and habitats from the coast to upper montane forest and subalpine scrub, rather than being restricted to predominantly greywacke rock within the subalpine to alpine zone of the main axial ranges of the North Island.
September - April
October - June
Minute pappate seeds are wind dispersed (Thorsen et al., 2009).
Easily grown from fresh seed. Not particularly attractive and inclined to become invasive.
epilobium: From the Greek epi- ‘upon’ and lobos ‘a pod’, the flowers appearing to be growing on the seed pod.
