Araucariaceae
Araucariaceae is a Family (biology), family of conifers with three living Genus, genera, ''Araucaria'', ''Agathis'', and ''Wollemia''. While the family's native distribution is now largely confined to the Southern Hemisphere, except for a few species of ''Agathis'' in Malesia, it was formerly widespread in the Northern Hemisphere during the Jurassic and Cretaceous periods. Description Members of Araucariaceae are typically extremely tall evergreen trees, reaching heights of or more. They can also grow very large stem diameters; a New Zealand kauri tree (''Agathis australis'') named ''Tāne Mahuta'' ("The Lord of the Forest") has been measured at tall with a diameter at breast height of . Its total wood volume is calculated to be , making it the third-largest conifer after ''Sequoia sempervirens, Sequoia'' and ''Sequoiadendron'' (both from the Cupressaceae subfamily Sequoioideae). The trunks are columnar and have relatively large piths with resinous Cortex (botany), cortices. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conifers
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 majority are trees, though a few are shrubs. Examples include cedars, Douglas-firs, cypresses, firs, junipers, kauri, larches, pines, hemlocks, redwoods, spruces, and yews.Campbell, Reece, "Phylum Coniferophyta". ''Biology''. 7th ed. 2005. Print. p. 595. As of 2002, Pinophyta contained seven families, 60 to 65 genera, and more than 600 living species. Although the total number of species is relatively small, conifers are ecologically important. They are the dominant plants over large areas of land, most notably the taiga of the Northern Hemisphere, but also in similar cool climates in mountains further south. Boreal conifers have many wintertime adaptations. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Podocarpaceae
Podocarpaceae is a large family of mainly southern hemisphere conifers, known in English as podocarps, comprising about 156 species of evergreen trees and shrubs.James E. Eckenwalder. 2009. ''Conifers of the World''. Portland, Oregon: Timber Press. . It contains 20 genera if ''Phyllocladus'' is included and ''Manoao'' and ''Sundacarpus'' are recognized. The family achieved its maximum diversity in the Cenozoic, making the Podocarpaceae family one of the most diverse in the southern hemisphere. The family is a classic member of the Antarctic flora, with its main centres of diversity in Australasian realm, Australasia, particularly New Caledonia, Tasmania, and New Zealand, and to a slightly lesser extent Malesia and South America (primarily in the Andes Mountains). Several genera extend north of the equator into Indochina and the Philippines. ''Podocarpus'' reaches as far north as southern Japan and southern China in Asia, and Mexico in the Americas, and ''Nageia'' into southern Ch ...

Wollemia Nobilis
''Wollemia'' is a genus of coniferous trees in the family Araucariaceae, endemic to Australia. It represents one of only three living genera in the family, alongside ''Araucaria'' and ''Agathis'' (being more closely related to the latter). The genus has only a single known species, ''Wollemia nobilis,'' commonly known as the Wollemi pine (though it is not a true pine) which was discovered in 1994 in a temperate rainforest wilderness area of the Wollemi National Park in New South Wales. It was growing in a remote series of narrow, steep-sided, sandstone gorges north-west of Sydney. The genus is named after the National Park. The Wollemi pine is classified as critically endangered (CR) on the IUCN's Red List, and is legally protected in Australia. After it was discovered that the trees could be successfully cloned, new trees were potted up in the Botanic Gardens of Sydney and Mount Annan and planted as far away as the Humboldt Botanical Garden near Eureka, California and in a gar ...

Alexander Doweld
Alexander () is a male name of Greek origin. The most prominent bearer of the name is Alexander the Great, the king of the Ancient Greek kingdom of Macedonia who created one of the largest empires in ancient history. Variants listed here are Aleksandar, Aleksander, Oleksandr, Oleksander, Aleksandr, and Alekzandr. Related names and diminutives include Iskandar, Alec, Alek, Alex, Alexsander, Alexandre, Aleks, Aleksa, Aleksandre, Alejandro, Alessandro, Alasdair, Sasha, Sandy, Sandro, Sikandar, Skander, Sander and Xander; feminine forms include Alexandra, Alexandria, and Sasha. Etymology The name ''Alexander'' originates from the (; 'defending men' or 'protector of men'). It is a compound of the verb (; 'to ward off, avert, defend') and the noun (, genitive: , ; meaning 'man'). The earliest attested form of the name, is the Mycenaean Greek feminine anthroponym , , (/Alexandra/), written in the Linear B syllabic script. Alaksandu, alternatively called ''Alakasandu'' or ...

Sciadopityaceae
Sciadopityaceae, commonly called umbrella pines, are a family of conifers now endemic to Japan but in prehistoric times they could also be found in Europe and China. The sole living member of the family is ''Sciadopitys verticillata'' (the kōyamaki tree), while several extinct genera are known from the fossil record. Wood suggested to belong to the family has been reported from the Jurassic of China, though the relationship of pre-Cretaceous fossils to ''Sciadopitys'' is ambiguous. ''Sciadopitys'' species are known from the Late Cretaceous of Japan before becoming widespread across Laurasia during most of the Cenozoic, especially in Europe until the Pliocene The Pliocene ( ; also Pleiocene) is the epoch (geology), epoch in the geologic time scale that extends from 5.33 to 2.58 [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cupressaceae
Cupressaceae or the cypress family is a family of conifers. The family includes 27–30 genera (17 monotypic), which include the junipers and redwoods, with about 130–140 species in total. They are monoecious, subdioecious or (rarely) dioecious trees and shrubs up to tall. The bark of mature trees is commonly orange- to red-brown and of stringy texture, often flaking or peeling in vertical strips, but smooth, scaly or hard and square-cracked in some species. The family reached its peak of diversity during the Mesozoic era. Description The leaves are arranged either spirally, in decussate pairs (opposite pairs, each pair at 90° to the previous pair) or in decussate whorls of three or four, depending on the genus. On young plants, the leaves are needle-like, becoming small and scale-like on mature plants of many genera; some genera and species retain needle-like leaves throughout their lives. Old leaves are mostly not shed individually, but in small sprays of foliage ( clad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cephalotaxaceae
Cephalotaxaceae is a small family of conifers. It is often treated as a monophyletic family including only the single genus '' Cephalotaxus'', while others have also included '' Torreya'' and ''Amentotaxus'' in the family. Cephalotaxaceae is closely allied to the yew family Taxaceae, and is often included in a wide interpretation of Taxaceae, based on phylogenetic evidence and close morphological similarities between them. Included species were restricted to east Asia, except for two species of '' Torreya'' found in the southwest and southeast of the United States; fossil evidence shows a much wider prehistorical Northern Hemisphere distribution. The most notable differences between Taxaceae and Cephalotaxaceae concerned the cone aril, which fully encloses the seeds of Cephalotaxaceae, the longer maturation of Cephalotaxaceae seeds and the larger size of the mature seeds. When considered as a distinct family, members of Cephalotaxaceae are much branched, small trees and shrubs. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxaceae
Taxaceae (), commonly called the yew family, is a coniferous family (biology), family which includes six Extant taxon, extant and two extinct genera, and about 30 species of plants, or in older interpretations three genera and 7 to 12 species. Description They are many-branched, small trees and shrubs. The leaves are evergreen, spirally arranged, often twisted at the base to appear 2-ranked. They are linear to lanceolate, and have pale green or white stomatal bands on the undersides. The plants are Plant sexuality, dioecious, or rarely Plant sexuality, monoecious. The catkin like male cones are long, and shed pollen in the early spring. They are sometimes externally only slightly differentiated from the branches. The fertile bracts have 2-8 pollen sacs. The female 'cones' are highly reduced. Only the upper or uppermost bracts are fertile and bear one or rarely two seeds. The ovule usually exceeds the scale, although ovules are sometimes rarely enclosed by it. They may be foun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
