Dumortiera hirsuta is a large thallose liverwort that grows in humid sites, often close to water. Its name is derived from the presence of minute hairs at the thallus margins. Threats to the species are poorly understood, but elsewhere it is at risk from tree-felling activities that reduce humidity and shade and from water pollution. The Glenarm locality is one of the northernmost known for the species, which reaches the northern limit of its world range in south-western Scotland. Species description The large dark green thalli are up to 12cm long and 2cm wide and these may form large mats or become pendent on steep substrata.
