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.

Features

Autoicous, tufted, saxicolous, blackish-green moss. Stems 5-10 mm tall, branched. Leaves 2.5-3.2 mm long, shorter below, suberect dry or wet, arising from a narrow insertion; lamina narrowly acuminate with blunt apices, bistratose above; margins plane, entire, multistratose below. Nerve usually indistinct above; failing below apex. Upper cells 10 microns, irregularly isodiametrical, smooth; basal cells shortly rectangular. Vaginula with a few short paraphyses, not or only indistinctly ochreate. Seta subsessile. Perichaetial bracts rather long. Capsule 1.50-1.90 mm long, entirely immersed on the subsessile seta; pyriform, coriaceous, exothecial cells strongly incrassate, smooth. Peristome single, rarely with a preperistome; teeth 16, pale, rather coarsely papillose, trabeculate on the ventral surface. Operculum conico-rostellate. Calyptra reddish brown, smooth plicate. Male inflorescence large, terminal at the end of very short branchlets, gemmiform.
