Actinostrobus
''Actinostrobus'' is a genus of coniferous trees in the Cupressaceae (cypress family). Common names include cypress, sandplain-cypress and cypress-pine, the last of these shared by the closely related genus '' Callitris''. Species There are three species in the genus, all endemic to southwestern Western Australia: A 2010 study of ''Actinostrobus'' and ''Callitris'' has placed all three species of ''Actinostrobus'' within an expanded ''Callitris'' based on analysis of 42 morphological and anatomical characters. They are shrubs or small trees, reaching tall. The leaves are evergreen, of two forms; juvenile needle-like leaves long on young seedlings (but occasional into adulthood in ''A. acuminatus''), and scale-like adult leaves, long with only the apex free. The leaves are arranged in six rows along the twigs, in alternating whorls of three. The male cones are small, long, and are located at the tips of the twigs. The female cones start out similarly inconspicuous, matu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Actinostrobus Pyramidalis
''Actinostrobus pyramidalis'', commonly known as swamp cypress, Swan River cypress and King George's cypress pine,Eckenwalder, J.E. 2009. ''Conifers of the World: The Complete Reference''. Timber Press. p. 124 is a species of coniferous tree in the Cupressaceae (cypress family). Like the other species in the genus ''Actinostrobus'', it is endemic to southwestern Western Australia. Swamp cypress is a shrub or small tree, reaching eight metres tall. The leaves are evergreen and scale-like, except on young seedlings, where they are needle-like. The leaves are arranged in six rows along the twigs, in alternating whorls of three. The male cones are small, 3–6 mm long, and are located at the tips of the twigs. The female cones start out similarly inconspicuous, but mature in 18–20 months to 1–2 cm with a rounded apex. The cones open and release the seeds only upon drying. They tend to remain closed on the trees for many years, opening only if the branch, or the whole ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Callitris
''Callitris'' is a genus of coniferous trees in the Cupressaceae (cypress family). There are 16 recognized species in the genus, of which 13 are native to Australia and the other three (''C. neocaledonica, C. sulcata'' and ''C. pancheri'') native to New Caledonia. Traditionally, the most widely used common name is cypress-pine, a name shared by some species of the closely related genus ''Actinostrobus''.Eckenwalder, J.E. 2009.

Actinostrobus Acuminatus
''Actinostrobus acuminatus'', commonly known as dwarf cypress, creeping pine or Moore cypress pine,Eckenwalder, J.E. 2009. ''Conifers of the World: The Complete Reference''. Timber Press. p. 123 is a species of coniferous tree in the Cupressaceae (cypress family). Like the other species in the genus ''Actinostrobus'', it is endemic to southwestern Western Australia, where it can be found along the shorelines of rivers. The Mount Henry Peninsula is an example of the environment in which this cypress is found. It shares the common name ''dwarf cypress'' with several other plants, and shares the name ''creeping pine'' with others. It is a shrub or small tree, reaching 1–4.5 m tall. The leaves are evergreen and mixed scale-like and needle-like, except on young seedlings, where they are all needle-like. The leaves are arranged in six rows along the twigs, in alternating whorls of three; the scale leaves are 2–4 mm long, the needle leaves 10–20 mm long. The male cone ...

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] |
Tree
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, e.g., including only woody plants with secondary growth, only plants that are usable as lumber, or only plants above a specified height. But wider definitions include taller palms, tree ferns, bananas, and bamboos. Trees are not a monophyletic taxonomic group but consist of a wide variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some trees reaching several thousand years old. Trees evolved around 400 million years ago, and it is estimated that there are around three trillion mature trees in the world currently. A tree typically has many secondary branches supported cle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conifer Cone
A conifer cone, or in formal botanical usage a strobilus, : strobili, is a seed-bearing organ on gymnosperm plants, especially in conifers and cycads. They are usually woody and variously conic, cylindrical, ovoid, to globular, and have scales and bracts arranged around a central axis, but can be fleshy and berry-like. The cone of Pinophyta (conifer clade) contains the reproductive structures. The woody cone is the female cone, which produces seeds. The male cone, which produces pollen, is usually ephemeral and much less conspicuous even at full maturity. The name "cone" derives from Greek ''konos'' (pine cone), which also gave name to the geometric cone. The individual plates of a cone are known as ''scales''. In conifers where the cone develops over more than one year (such as pines), the first year's growth of a seed scale on the cone, showing up as a protuberance at the end of the two-year-old scale, is called an ''umbo'', while the second year's growth is called th ...

Flora Of Western Australia
The flora of Western Australia comprises 10,842 published native vascular plant species and a further 1,030 unpublished species. They occur within 1,543 genus, genera from 211 Family (biology), families; there are also 1,335 naturalised alien or invasive plant species more commonly known as weeds. There are an estimated 150,000 cryptogam species or nonvascular plants which include lichens, and fungi although only 1,786 species have been published, with 948 algae and 672 lichen the majority. History Indigenous Australians have a long history with the flora of Western Australia. They have for over 50,000 years obtained detailed information on most plants. The information includes its uses as sources for food, shelter, tools and medicine. As Indigenous Australians passed the knowledge along orally or by example, most of this information has been lost, along many of the names they gave the flora. It was not until Europeans started to explore Western Australia that systematic written de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conifer
Conifers () are a group of conifer cone, cone-bearing Spermatophyte, seed plants, a subset of gymnosperms. Scientifically, they make up the phylum, division Pinophyta (), also known as Coniferophyta () or Coniferae. The division contains a single extant class (biology), class, Pinopsida. All Neontology, extant conifers are perennial plant, perennial woody plants with secondary growth. The majority are trees, though a few are shrubs. Examples include Cedrus, cedars, Pseudotsuga, Douglas-firs, Cupressaceae, cypresses, firs, junipers, Agathis, kauri, larches, pines, Tsuga, hemlocks, Sequoioideae, redwoods, spruces, and Taxaceae, 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 ecology, ecologically important. They are the dominant plants over large areas of land, most notably ...
