Dacrydium cupressinum, commonly known as rimu, is a large evergreen coniferous tree endemic to the forests of New Zealand. It is a member of the southern conifer group, the podocarps. The former name "red pine" has fallen out of common use.
An IUCN Red List Critically Endangered (CR) species is one that has been categorized by the International Union for Conservation of Nature as facing an extremely high risk of extinction in the wild. As of 2021, of the 120,372 species currently tracked by the IUCN, there are 8,404 species that are considered to be Critically Endangered.
Notiosorex cockrumi, also called Cockrum's gray shrew or Cockrum's desert shrew, is a tiny species of shrews named in 2003. This red-toothed shrew, which is as light as a penny, is the first new mammal species from Arizona since 1977. Its range extends from Arizona to central Sonora, Mexico.
Bannerman's weaver is a species of bird in the weaver family, Ploceidae. It is found in Cameroon and Nigeria. Its natural habitat is subtropical or tropical moist montane forests. It is threatened by habitat loss.
Hymenophyllum alveolatum is a species of fern in the family Hymenophyllaceae. It is endemic to Ecuador. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests. It is threatened by habitat loss.
Hymenophyllum is a genus of ferns in the family Hymenophyllaceae. Its name means "membranous leaf", referring to the very thin translucent tissue of the fronds, which gives rise to the common name filmy fern for this and other thin-leaved ferns. The leaves are generally only one cell thick and lack stomata, making them vulnerable to desiccation. Consequently, they are found only in very humid areas, such as in moist forests and among sheltered rocks. They are small and easy to overlook.
Hymenophyllum brachypus is a species of fern in the family Hymenophyllaceae. It is endemic to Ecuador. Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss.
Hymenophyllum contractile is a species of fern in the family Hymenophyllaceae. It is endemic to Ecuador. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests. It is threatened by habitat loss.
Hymenophyllum cristatum is a species of fern in the family Hymenophyllaceae. It is endemic to Ecuador. Its natural habitats are subtropical or tropical moist montane forests and subtropical or tropical high-altitude grassland. It is threatened by habitat loss.
Hymenophyllum helicoideum is a species of fern in the family Hymenophyllaceae. It is endemic to Ecuador. Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss.
Hymenophyllum nanum is a species of fern in the family Hymenophyllaceae. It is endemic to Ecuador, where it is known from two old collections in Pichincha Province. Its natural habitat is the forest of the lower Andes. It is threatened by habitat loss.
Hymenophyllum refrondescens is a species of fern in the family Hymenophyllaceae. It is endemic to Ecuador. Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss.
Hymenophyllum sodiroi is a species of fern in the family Hymenophyllaceae. It is endemic to Ecuador. Its natural habitat is subtropical or tropical moist montane forests. It is threatened by habitat loss.
Hymenophyllum tenerum is a species of fern in the family Hymenophyllaceae. It is endemic to Ecuador. Its natural habitat is subtropical or tropical moist montane forests. It is threatened by habitat loss.
Hymenophyllum trifidum is a species of fern in the family Hymenophyllaceae. It is endemic to Ecuador. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests. It is threatened by habitat loss.
Hymenophyllum nephrophyllum, the kidney fern, is a filmy fern species native to New Zealand. It commonly grows on the forest floor of open native bush. Individual kidney-shaped fronds stand about 5–10 cm tall. In hot weather they shrivel up to conserve moisture, but open up again when the wet returns. This species has very thin fronds which are only four to six cells in thickness. In the Māori language they are also called raurenga.
Hymenophyllum australe, commonly known as austral filmy fern, is a relatively large rupestral and epiphytic fern, indigenous to eastern Australia and New Zealand. It belongs to the unique Hymenophyllum genus, which are characterised by their thin membranous fronds that are seldom more than one cell thick, with the exception of regions over and around veins. Hymenophyllum australe is distinctive in that the fronds are typically thicker than other Hymenophyllum species, often being up to 2-3 cells thick.
Hymenophyllum wilsonii, the Wilson's filmy-fern, is a small, fragile, perennial leptosporangiate fern which forms large dense colonies from creeping rhizomes.
Hymenophyllum tunbrigense, the Tunbridge filmy fern or Tunbridge filmy-fern, is a small, fragile perennial leptosporangiate fern which forms large dense colonies of overlapping leaves from creeping rhizomes. The common name derives from the leaves which are very thin, only a single cell thick, and translucent, giving the appearance of a wet film. The evergreen fronds are bipinnatifid, deeply and irregularly dissected, about 3 to 6 cm long, 2 cm across with dark winged stipes. In contrast to the similar H. wilsonii the fronds are more divided, flattened, appressed to the substrate and tend to have a bluish tint.
Hymenophyllum bivalve is a species of filmy fern. Found in moist sheltered areas, in or near mountain rainforests in Australia and New Zealand. The habitat is on tree trunks, rocks and fallen logs.
