The threat status of New Zealand's bryophytes (currently 13 hornwort species, 608 liverwort species and 520 moss species) has been re‐evaluated, using revised New Zealand Threat Classification System criteria. Threatened or uncommon status has been applied to 269 taxa (c. 24% of the total number of species) and to 25 entities that are either described but disputed or are undescribed. No taxa are known to be extinct. Forty‐one...

The aquatic moss Hypnobartlettia fontana Ochyra was described, and placed in its own family, the Hypnobartlettiaceae, based on material collected at Te Waikoropupuu (“Pupu Springs”), Takaka, Nelson, New Zealand. It is known only from the type locality. Based on morphological evidence, we conclude Hypnobartlettia fontana is an environmentally induced form of the very variable Cratoneuropsis relaxa (Hook.f. & Wilson) Broth, modi...

A review of bryophyte records from New Zealand lakes showed a “deep‐water” assemblage occurred at ≥ 10 m depths within 16 lakes all of which possessed high water clarity (1/ K d >3). Bryophyte depth limits ranged from 12 to 70 m. Depth limit was significantly related to water clarity and extended to where the level of irradiance was 0.2–1% of light incident on the lake surface. Deep‐water bryophytes were generally absent from...
