Acmopyle is a genus of conifers belonging to the podocarp family, Podocarpaceae. The genus includes two species of evergreen small to tall well-branched trees and large trees. Acmopyle is limited to two species, A. pancheri , endemic to New Caledonia, and A. sahniana , endemic to Fiji, but has a fossil record in Australia.

Conifers are a group of cone-bearing seed plants, a subset of gymnosperms. Scientifically, they make up the division Pinophyta, also known as Coniferophyta or Coniferae. The division contains a single extant class, Pinopsida. All extant conifers are perennial woody plants with secondary growth. The great majority are trees, though a few are shrubs. Examples include cedars, Douglas-firs, cypresses, firs, junipers, kauri, larches, pines, hemlocks, redwoods, spruces, and yews. As of 1998, the division Pinophyta was estimated to contain eight families, 68 genera, and 629 living species.
Podocarpaceae is a large family of mainly Southern Hemisphere conifers, comprising about 156 species of evergreen trees and shrubs. It contains 19 genera if Phyllocladus is included and Manoao and Sundacarpus are recognized.
Phyllocladus, the celery pines, is a small genus of conifers, now usually treated in the family Podocarpaceae.Species occur mainly in New Zealand, Tasmania, and Malesia in the Southern Hemisphere, though P. hypophyllus ranges into the Philippines, a short way north of the equator.
Lagarostrobos franklinii is a species of conifer native to the wet southwestern corner of Tasmania, Australia. It is often known as the Huon pine or Macquarie pine, although it is actually a podocarp (Podocarpaceae), not a true pine (Pinaceae). It is the sole species in the genus Lagarostrobos; one other species L. colensoi formerly included has been transferred to a new genus Manoao. The genus was also formerly included in a broader circumscription of the genus Dacrydium.
Podocarpus is a genus of conifers, the most numerous and widely distributed of the podocarp family, the Podocarpaceae. The name comes from Greek πούς + καρπός. Podocarpus species are evergreen shrubs or trees, usually from 1 to 25 m tall, known to reach 40 m (130 ft) at times. The cones have two to five fused cone scales, which form a fleshy, berry-like, brightly coloured receptacle at maturity. The fleshy cones attract birds, which then eat the cones and disperse the seeds in their droppings. About 97 to 107 species are placed in the genus depending on the circumscription of the species.
Nageia is a genus of conifers belonging to the podocarp family Podocarpaceae. Nageia includes evergreen shrubs and trees, from one to 54 meters in height. A 2009 treatment of the genus recognized five species. Some authors consider Nageia formosensis to be a separate species from Nageia nagi, thus recognizing six species. The podocarp genera have been reshuffled by various botanists. Most recently, several species formerly classed as Nageia were moved to the new genus Retrophyllum, while Nageia falcata and Nageia mannii were moved to the new genus Afrocarpus.
Afrocarpus is a genus of conifers of the family Podocarpaceae. Two to six species are recognized. They are evergreen trees native to Africa. Afrocarpus was designated a genus in 1989, when several species formerly classified in Podocarpus and Nageia were reclassified.
Prumnopitys is a genus of conifers belonging to the family Podocarpaceae. The nine recognized species of Prumnopitys are densely branched, dioecious evergreen trees up to 40 metres in height.
Dacrydium is a genus of conifers belonging to the podocarp family Podocarpaceae. Sixteen species of evergreen dioecious trees and shrubs are presently recognized. The genus was first described by Solander in 1786, and formerly included many more species, which were divided into sections A, B, and C by Florin in 1931. The revisions of de Laubenfels and Quinn, reclassified the former section A as the new genus Falcatifolium, divided Section C into new genera Lepidothamnus, Lagarostrobos and Halocarpus, and retained Section B as genus Dacrydium.
Dacrycarpus is a genus of conifers belonging to the family Podocarpaceae. The genus includes nine species of dioecious evergreen trees and shrubs to 55–60 metres (180–197 ft) in height.
Halocarpus is a genus of conifers of the family Podocarpaceae. The genus includes three closely related species of evergreen trees and shrubs, all endemic to New Zealand.
Manoao is a monotypic genus in the family Podocarpaceae. The single species, M. colensoi, known as manoao (Māori), silver pine, Westland pine, or white silver pine, is endemic to New Zealand. Before 1996 it was classified in genus Dacrydium or Lagarostrobos, but has recently been recognised as a distinct genus; some botanists still treat it in Lagarostrobos on the basis that it is not phylogenetically distinct from that genus. In molecular phylogenetic analyses Manoao was found to be related to Parasitaxus and Lagarostrobos, but their exact relationships are unresolved.
The biodiversity of New Caledonia is of exceptional biological and paleoecological interest. It is frequently referred to as a biodiversity hotspot. The country is a large South Pacific archipelago with a total land area of more than 18,000 square kilometres (6,900 sq mi). The terrain includes a variety of reefs, atolls, small islands, and a variety of topographical and edaphic regions on the largest island, all of which promote the development of unusually concentrated biodiversity. The region's climate is oceanic and tropical.
The New Caledonia rain forests are a terrestrial ecoregion, located in New Caledonia in the South Pacific. It is a tropical moist broadleaf forest ecoregion, part of the Australasian realm.
Microcachrys tetragona, the creeping pine or creeping strawberry pine, is a species of dioecious conifer belonging to the podocarp family (Podocarpaceae). It is the sole species of the genus Microcachrys. The plant is endemic to western Tasmania, where it is a low shrub growing to 1 m tall at high altitudes. Its leaves are scale-like, arranged in opposite decussate pairs, superficially resembling those of the unrelated Diselma archeri (Cupressaceae). It shares the common name Creeping pine with several other plants. Females produce tiny, red, edible berries in summer.
Retrophyllum is a genus of conifers in the family Podocarpaceae. It contains five generally recognized extant species with a disjunct distribution in the Southern Hemisphere, found in Papuasia and also in South America. Retrophyllum are evergreen trees typically occurring in tropical rainforests and cloud forests.
Diselma archeri is a species of plant of the family Cupressaceae and the sole species in the genus Diselma. It is endemic to the alpine regions of Tasmania's southwest and Central Highlands, on the western coast ranges and Lake St. Clair. It is a monotypic genus restricted to high altitude rainforest and moist alpine heathland. Its distribution mirrors very closely that of other endemic Tasmanian conifers Microcachrys tetragona and Pherosphaera hookeriana.
Halocarpus bidwillii, commonly known as the mountain pine or bog pine, is a species of conifer in the family Podocarpaceae. It is endemic to New Zealand.
Lepidothamnus laxifolius, commonly known as the pygmy pine or mountain rimu, is a species of conifer in the family Podocarpaceae. It is endemic to New Zealand, where it is found in the North Island, the South Island and on Stewart Island.
Podocarpus laetus is a species of conifer in the family Podocarpaceae, commonly known as Hall's tōtara, mountain tōtara or thin-barked tōtara. Previously known as Podocarpus hallii and Podocarpus cunninghamii, in 2015 it was realised that the much earlier name P. laetus has priority. Its common name results from the species being named after J. W. Hall, a New Zealand pharmacist.
