Current Conservation Status

2009 - At Risk - Naturally Uncommon

Conservation status of New Zealand indigenous vascular plants, 2012
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2012 using the New Zealand Threat Classification System (NZTCS). This report includes a statistical summary and brief notes on changes since 2009 and replaces all previous NZTCS lists for vascular plants. Authors: Peter J. de Lange, Jeremy R. Rolfe, Paul D.

Flora Category

Non Vascular - Native

Structural Class



Anictangium lapponicum Hedw.; Amphidium sublapponicum (C. Müll.) Broth.; Zygodon sublapponicus C. Müll.


Indigenous. New Zealand: North and South Islands. Also China, Japan, Central Asia, Europe, Greenland, Iceland, and North America


Terricolous on moist rocks in montane forest and subalpine scrub.


Plants small to medium-sized, up to 35 mm tall, dark green or yellowish brown, in dense tufts. Stems erect, simple or forked, radiculose below. Leaves strongly curled and contorted when dry, narrowly oblong- to linear-lanceolate; margins irregularly and narrowly recurved below, entire or indistinctly sinuate above; costa single, strong, ending near the leaf apex, papillose on both sides; upper laminal cells rounded-hexagonal, 8–10 µm in diameter, thick-walled, very opaque, densely warty-papillose; lower cells slightly larger, rectangular, thin-walled, hyaline or pale yellowish, smooth; alar cells not differentiated. Autoicous. Perichaetial leaves greatly enlarged, entirely sheathing, broad at base, short-pointed at the apex. Setae up to 2 mm long, as long as or shorter than perichaetial leaves; capsules shortly emergent, 1.0–1.3 mm long. Spores 9–12 µm in diameter, usually smooth or nearly so.


Fruiting material is known from New Zealand but there are insufficient gatherings as yet to determine periodicity


Amphidium lapponicum is known from very few sites, all of which are located within protected land. There are no known threats. For this reason Amphidium has been listed as "Naturally Uncommon" (see Glenny et al. 2011).
