Leaves numerous, rather dense toward stem tips, spreading, slightly curled, when dry, scarcely sheathing from a narrowly ovate base; lamina lanceolate, acuminate; margins recurved, finely serrulate; nerve distinct, excurrent, conspicuously broad, occupying c.1/3 of width of sheath up to the middle of the subula; exposed portion of nerve on underside of leaf finely papillate, rugose; subula denticulate especially above, toward the apex; lower cells elongate, upper quadrate, clear, incrassate to papillose, 7-11 microns long, more or less isodiametrical; perichaetial broader. Seta up to 10 mm long, red; operculum convex, apiculate.
Distribution
Endemic. South Island, Westland (Mt Cassidy) and Otago (Hopkins Valley)
Substrate details
Saxicolous on schist rock, montane to alpine
Threats
Seemingly very uncommon and known from only one recent gathering (1980s) gathering. Probably better assessed as Data Deficient.
