Current conservation status
The conservation status of the New Zealand hornwort and liverwort flora is reassessed using the New Zealand Threat Classification System (NZTCS). A full list is presented, along with a statistical summary and brief notes on the most important changes. This list replaces all previous NZTCS lists for New Zealand hornworts and liverworts which previously had been part of a generic bryophyte conservation status assessment that included mosses.

Detailed description
Plants soft, loosely creeping, whitish green no secondary pigments seen. Branches of Frullania type, the ½-leaf ovate to sublanceolate; ventral-intercalary type branches common. Stems with cortical cells in 12-13 rows, firm-walled, not sharply differentiated, slightly to at most moderately larger than those of medulla; medullary cells firm-walled. Rhizoids scattered hyaline. Leaves vertically orientated, strongly dorsally assurgent, variably spreading, suberect to obliquely so, distant to contiguous, succubously to subtransversely orientated, the insertion weakly to strongly succubous, extending virtually to stem midline dorsally, the leave abruptly so and the lobe tips then claw-like. Moderately to narrowly acute, the apices terminating in a single cell or a uniseriate row of 2 cells at most slightly longer than wide, the lobes 8-10 cells wide at base; lamina 12-14 cells wide. Gemmae lacking. Underleaves absent.
Distribution
Endemic. South Island. Arthur’s Pass and Fiordland National Park
Substrate details
Alpine. On rock in deep cracks and holes with other liverworts.
Threats
Probably not threatened but because it is an alpine species and very, very small it is easily overlooked and so still poorly known.
