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. North and South Islands. In the North Island from Little and Great Barrier Islands south to Taranaki, Lake Taupo and the northern Hawkes Bay. In the South Island present from the Marlborough Sounds south to and west to Jacksons Bay.
A rheophytic species favouring the flood zone of steep-sided streams, rivers and deep gorges. It usually grows with its roots immersed in flowing water, or in damp seepages, or permanently damp but draining moss lined cliff faces. It has also been found to be locally abundant along the bases of ignimbritic cliffs lining the shores of Lake Taupo, where it grows just within the spray zone of the lake - often with Hymenophyllum atrovirens (see Fact Sheet for that species)
Bright green tufted fern with pendulous heavily divided narrow fronds, occurring either as solitary plants or large patches in permanently damp places. Rhizomes short-creeping, ascending, scaly. Stipes 30-120 mm long, purplish brown. Fronds bright green, narrowly elliptic, narrowly ovate to lanceolate, 2-3-pinnate, 40-300 x 10-50 mm, pendulous, bright green. Pinnae in 7-20 pairs, aside from the basal 1-2 pairs overlapping. Ultimate segments 4-7 x 1-25 mm, broadest above the middle, blunt-ended, with smooth or toothed margins. Sori at ends of ultimate segments, almost round or broader than long. Indusia oblong to elongated cream to light green coloured, margins smooth or toothed.
Rather distinctive and unlikely to be confused with any other New Zealand fern species, especially because of the habitat which it occupies. However, it could be confused with the forest dwelling L. trichomanoides. Aside from its ecology that species differs from L. viridis by its upright, less divided, wider fronds bearing fewer pinnules which scarcely (if ever) overlap with the adjoining pairs, and by its much longer creeping rhizomes.

Difficult - should not be removed from the wild
This species is a naturally uncommon, sparsely distributed fern, which on occasion (such as the western cliff lined shores of Lake Taupo) can be extremely common, but which is more usually known at any particular site by a handful of plants. As such at some locations it is extremely vulnerable to over collection.
lindsaea: Named after John Lindsay, 19th century British surgeon who discovered fern spore
viridis: From the Latin viridis ‘green’
