Abstract
A list of mosses, comprising 52 species from 23 families, is provided for the Kermadec Islands, northern New Zealand. Cyclodictyon blumeanum is recorded new to New Zealand. Hypnum trachypelma is placed in synonymy with Eurhynchium speciosum, and lectotypes are designated for the names Hypnum trachypelma and Neckera kermadecensis. The moss flora of the Kermadec Islands contributes a significant subtropical element to the New Zealand mainland flora.
