By far the most common Macromitrium on the islands. This species ( a dubious species at best) is the only moss believed endemic to the Chatham Islands.

Description

Locally common on Rekohu (Chatham Island). Mostly seen around settlements, or within sites of former habitation. Still widely cultivated on the island and mostly noted 'wild' as a cultivation relict or as deliberate plantings that appear 'wild'. However, also noted on cliff faces and in sites where garden waste had or hast been dumped. These images are of plants that are genuinely self-established within the main vehicle park between the Waitangi Hotel and Fish Factory.
