The Marchantiophyta are a division of non-vascular land plants commonly referred to as hepatics or liverworts. Like mosses and hornworts, they have a gametophyte-dominant life cycle, in which cells of the plant carry only a single set of genetic information.
Ulva Island is a small island about 3.5 km (2.17 mi) long lying within Paterson Inlet, which is part of Stewart Island/Rakiura in New Zealand.
Barthélemy Charles Joseph Dumortier was a Belgian who conducted a parallel career of botanist and Member of Parliament.
Metzgeriales is an order of liverworts. The group is sometimes called the simple thalloid liverworts: "thalloid" because the members lack structures resembling stems or leaves, and "simple" because their tissues are thin and relatively undifferentiated. All species in the order have a small gametophyte stage and a smaller, relatively short-lived, spore-bearing stage. Although these plants are almost entirely restricted to regions with high humidity or readily available moisture, the group as a whole is widely distributed, and occurs on every continent except Antarctica.
Takakia is a genus of two species of mosses known from western North America and central and eastern Asia. The genus is placed as a separate family, order and class among the mosses. It has had a history of uncertain placement, but the discovery of sporophytes clearly of the moss-type firmly supports placement with the mosses.
Asteliaceae is a family of flowering plants, placed in the order Asparagales of the monocots.
Lepidozia is a genus of liverwort in the family Lepidoziaceae. It was first proposed by Dumortier in 1835.
Phycolepidozia exigua is a species of liverwort in the family Cephaloziellaceae. It was thought to be the only species in the genus until a new species from India, Phycolepidozia indica, was found in 2014. Phycolepidozia exigua is endemic to Dominica, where it is critically endangered. Its natural habitat is subtropical or tropical moist lowland forests.
Haplomitriopsida is a newly recognized class of liverworts comprising fifteen species in three genera. Recent cladistic analyses of nuclear, mitochondrial, and plastid gene sequences place this monophyletic group as the basal sister group to all other liverworts. The group thus provides a unique insight into the early evolution of liverworts in particular and of land plants in general.
Ptilidium is a genus of liverwort, and is the only genus in family Ptilidiaceae. It includes only three species: Ptilidium californicum, Ptilidium ciliare, and Ptilidium pulcherrimum. The genus is distributed throughout the arctic and subarctic, with disjunct populations in New Zealand and Tierra del Fuego. Molecular analysis suggests that the genus has few close relatives and diverged from other leafy liverworts early in their evolution.
Trichotemnoma is a genus of liverworts restricted to New Zealand and Tasmania, and contains a single species Trichotemnoma corrugatum. It is classified in the order Jungermanniales and is the only member of the family Trichotemnomataceae within that order. The generic name Trichotemnona was originally published in 1964, but that publication was invalid under the ICBN.
Acrobolbus epiphytus is a liverwort species in the genus Acrobolbus. It occurs in New Zealand.
Leiomitra is a genus of liverworts in the family Trichocoleaceae.
Trichocolea mollissima is a large liverwort of the Trichocoleaceae family. It is found commonly throughout wet sclerophyll and rainforests in Australia and New Zealand. In Australia it is present in Tasmania, Victoria, New South Wales and Queensland. It also occurs extensively on the north island of New Zealand. Its most distinctive feature is its highly divided, densely arranged and extremely small leaves, which lend it a woolly appearance; hence its common name “woolly worm”. It usually grows in a matted or tufted habit on the ground and lower trunks of trees, and exhibits a preference for decaying wood and deep shade. On casual observance, its leaf arrangement and growth habit resemble that of a large moss. Its stems are commonly 3–6 cm long, with leaves up to 0.6mm wide, with up to 3-3 divisions. leaves and stems are arranged in bi-pinnate form. It is commonly coloured pale-yellow-green, which fades to white or blue-green upon desiccation in drier conditions.
Handbook of the New Zealand Flora is a two volume work by English botanist Joseph Dalton Hooker with systematic botanical descriptions of plants native to New Zealand. The first part published in 1864 covers flowering plants, and the second part published in 1867 covers Hepaticae, mosses, lichens, fungi and algae.
Petalophyllum, or petalwort, is a genus of liverworts in the order Fossombroniales.
Castanoclobos is a monotypic genus of liverworts belonging to the family Pseudolepicoleaceae.
Monoclea forsteri is one of the two species in the thallose liverwort family Monocleaceae. It is dioicous with the capsule dehiscing with a single longitudinal slit. Endemic and widely distributed throughout New Zealand, it is also the country's largest thalloid liverwort. Hooker described the species in 1820. The holotype is in the British Museum.
Lophocolea mediinfrons is a species of liverwort in the family Lophocoleaceae. The plant was first described by John J. Engel and John E. Braggins in 2010 as Chiloscyphus mediinfrons, and has only been found on Ulva Island in New Zealand.
Schizophyllopsis papillosa is a species of liverwort in the family Anastrophyllaceae. The species was first identified as Anastrophyllum papillosum by John J. Engel and John E. Braggins and Rudolf M. Schuster in 1998.
