Hymenophyllum antarcticum C.Presl
Vascular – Native
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.

Indigenous. New Zealand: North, South and Chatham Islands, from the Bay of Islands to south Canterbury. Most common in the Hauraki Gulf, south-eastern North Island (and in the Mangaharuru, Kaweka, Kaimanawa and Ruahine Ranges) and in North-west Nelson. Also in Australia (Queensland, New South Wales, Victoria and Tasmania).
Coastal to montane. Usually rupestral in lightly shaded habitats. Rarely a low epiphyte on tree trunks and exposed roots.
Rhizome long-creeping, slender, pliant, glabrescent. Fronds 20-90 mm long. Stipes widely spaced, 5-40 mm long, usually narrowly winged, ± glabrous. Lamina dark green, elliptic-oblong, deeply 2-pinnatifid, 10-80 mm long, 10-25 mm wide; sometimes with a pair of shortly stalked basal pinnae present; secondary segments branching from both sides of the costae, simple or 2- or more times divided. Ultimate segments 05-1.0 mm wide; margins sharply toothed. Sori borne on short basal segments on the acroscopic side of the pinnae, solitary; involucre obovate, bilabiate, divided to the middle or below, 1.0-1.5 mm long, 1.3-2.0 mm wide, much wider than the ultimate segments; base cuneate, slightly immersed; margins ± entire to irregular, or finely toothed; receptacle included or slightly exserted. Description adapted from Bostock & Spokes (1998) and Brownsey & Smith-Dodsworth (2000).
Most often confused with Hymenophyllum revolutum with which it sometimes grows, and from which it is distinguished by its winged rachises and less prominently toothed indusial flaps. In the montane part of its range it may be confused with Hymenophyllum peltatum from which it differs by having solitary sori, and by its secondary pinnae which arise on both sides of the primary pinnae
Minute spores are wind dispersed (Thorsen et al., 2009).
