Epipterygium opararense

Epipterygium opararense (also Epipterygium obovatum[1]) is a species of moss from the Mniaceae family that is only known to grow in one site in the Kahurangi National Park in New Zealand's South Island. The Department of Conservation assigned it the rating of 'nationally critical' in 2002.[2] It has been proposed for inclusion in the IUCN Red List.[3]

Epipterygium are found in humid and warm regions, mainly in Central America.[4] Epipterygium opararense is the only Epipterygium moss that grows in Australasia.[5] It has 1/2 phyllotaxy (leaves are located one above the other, rotated 180°), which is unique for the genius, which usually has 2/5; it is probably an evolutionary adaptation to the darkness of the habitat.[6] The colour of the plants is pale green or brownish-green, while individual stalks have a yellow or red shade of brown.[7] Several 15-mm unbranched stalks with distichously arranged single leaves grow from a common point.[7] The leaves' are elliptic; their dimensions are 1.5—2.1 x 0.7—0.85 mm; the closer they are to the base, the smaller they become.[8] The moss is dioicous and has no sporophytes.[9] The moss seems to be stable on granite surfaces but not elsewhere: it forms only ephemeral colonies in decaying tree trunks; the scarcity of granites in New Zealand might be the reason why the moss is so rare.[10][1]

The holotype of Epipterygium opararense was gathered by Allan Fife on 16 December 1984 with the first spieces description published in 1990 by Fife & Shaw.[7][2] The paratype grew among Metrosideros diffusa rootlets in one locality on overhanging surface of coarse porphyritic potassic granite boulders and on moist humus around one of the Ōpārara Basin Arches in the Ōpārara River valley.[9][2][11] In 1991, Ryszard Ochrya reported a collection of Epipterygium opararense in Kakapo Saddle, but David Glenny failed to find any specimens at that location in 1994.[1] In 1992, Glenny found Epipterygium opararense inside rotten trees 1.5 km away from the Ōpārara Basin Arches.[2]

During a survey conducted in March 2005, around 175 plants were identified by Allan Fife and Philip Knightbridge, with all of them growing in two sites located very close to each other.[12] The site identified by Glenne did not include any Epipterygium opararense specimens by 2005; moreover, in one of the sites, Epipterygium opararense is threatened by the thallose liverwort (Marchantia foliacia).[2] Fife and Knightbridge wrote a communication to the Department of Conservation highlighting the urgent need to protect the species.[13] In 2008, the population suffered major damage from a windthrow with not more than 50 specimens left growing on site.[3] Allan Fife and Jane Marshall identified 30-35 plants on a granite overhang in an area with diameter of approximately 80 mm.[14]
