Sequoiadendron giganteum (Giant-sequoia) (Lindl.) J.Buchholz 1939
endangered plant species in the cupressaceae family
Sequoiadendron giganteum (also known as the giant sequoia, giant redwood, Sierra redwood or Wellingtonia) is a species of coniferous tree, classified in the family Cupressaceae in the subfamily Sequoioideae. Giant sequoia specimens are the largest trees on Earth. They are native to the groves on the western slopes of the Sierra Nevada mountain range of California but have been introduced, planted, and grown around the world. The giant sequoia is listed as an endangered species by the IUCN with fewer than 80,000 remaining in its native California. The giant sequoia grow to an average height of

plant genus in the cupressaceae family
Sequoiadendron is a genus of evergreen trees, with three species, only one of which survives to the present: Sequoiadendron giganteum, extant, commonly known as wellingtonia, giant redwood and giant sequoia, growing naturally in the Sierra Nevada mountains of California † Sequoiadendron chaneyi, the predecessor of Sequoiadendron giganteum, found mostly in the Nevada area of the Tertiary Colorado Plateau until the late Miocene †Sequoiadendron tchucoticum Late Cretaceous; Enmyvaam River Basin, Russia

The largest areas are in central Texas, where extensive stands occur. Ashe juniper grows up to 10 metres (33 feet) tall, and over time can reach 15 m (49 ft), and provides erosion control and year-round shade for wildlife and livestock.
Araucaria biramulata (Piggyback Araucaria) J.Buchholz 1949
plant species in the araucariaceae family
Araucaria biramulata, the biramule araucaria, or piggyback araucaria, is a species of conifer in the family Araucariaceae. It is found only in New Caledonia on the main island of Grande Terre. Araucaria biramulata is a medium-large tree reaching 30 meters in height. As with several other endemic New Caledonian araucaria species, it is threatened by habitat loss with a fragmented wild population of less than 10,000 mature trees, and ongoing decline in remaining populations, with the main threats being forest fires and mining activities. Piggyback araucaria gets its common name from the unusual
Araucaria humboldtensis (Humboldt's Araucaria) J.Buchholz 1949
vulnerable plant species in the araucariaceae family
Araucaria humboldtensis, or Humboldt's araucaria, is a species of conifer in the family Araucariaceae. It is found only in New Caledonia. It is threatened by habitat loss, as even though the remaining wild populations are located within protected park areas, an increased frequency of forest fires in recent years has led to continued degradation of habitat and increased dieback of mature trees. Araucaria humboldtensis is one of the smaller trees in its family, ranging from 6–15 m in height, with a distinct flattened crown in mature specimens. It is found in the wild only in three remnant
Araucaria bernieri (Bernier's Araucaria) J.Buchholz 1949
plant species in the araucariaceae family
Araucaria bernieri, commonly known as Bernier's columnar araucaria, is a species of conifer in the family Araucariaceae. It is found only in New Caledonia at elevations below 700 meters, mainly in the southern part of the main island. It is a large tree reaching 40–50 meters in height, though specimens growing on poorer soil tend to be dwarfed. It is threatened by habitat loss with a wild population of less than 10,000 mature trees, and ongoing decline in remaining populations.
Acmopyle sahniana (Fiji Acmopyle) J.Buchholz & N.E.Gray 1947
critically endangered plant species in the podocarpaceae family
Acmopyle sahniana is a species of conifer in the family Podocarpaceae. It is found only in Fiji. It is threatened by habitat loss.
Libocedrus chevalieri J.Buchholz 1949
vulnerable plant species in the cupressaceae family
Libocedrus chevalieri is a species of conifer in the cypress family, Cupressaceae. It is endemic to New Caledonia, occurring in three small, isolated populations on low mountain summits at 650–1,620 m altitude in cloud forest scrub on serpentine soils. It is threatened by habitat loss. It is an evergreen coniferous shrub (rarely a small tree) growing to 5 m tall, often multi-stemmed, with trunks up to 10 cm diameter. The foliage is arranged in flattened sprays; the leaves are scale-like, 2.5–5 mm long and 2–2.5 mm broad, arranged in opposite decussate pairs on the shoots. The seed cones are
