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. ''Conifers of the World: The Complete Reference''. Timber Press. p. 122-124 Description They are small to medium-sized trees or large shrubs, reaching tall (to in ''Callitris macleayana, C. macleayana''). The leaf, leaves are evergreen and scale-like, but young seedlings have needle-like leaves; in ''Callitris macleayana, C. macleayana'', needle-like leaves are found mixed with scale leaves throughout the tree's life. The scales are arranged in six rows along the twigs, in alternating whorls of three (often in whorls of four in ' ...

Callitris Rhomboidea
''Callitris rhomboidea'', commonly known as the Oyster Bay pine, Tasmanian cypress pine, Port Jackson pine, Illawarra mountain pine, or dune cypress pine, is a species of conifer in the family Cupressaceae. It is native to Australia, occurring in South Australia, Queensland, New South Wales, Victoria and Tasmania. It has become naturalized near Auckland, New Zealand, and can be found on the island of Taillefer Rocks in Tasmania. Description ''Callitris rhomboidea'' is a spreading evergreen shrub or small tree growing to 15 meters tall. The hairless leaves are keeled dorsally, green or glaucous in colour, and typically measure 2-3 mm long, though some may grow to 7 mm. This species is monoecious. The female cones In geometry, a cone is a three-dimensional figure that tapers smoothly from a flat base (typically a circle) to a point not contained in the base, called the ''apex'' or '' vertex''. A cone is formed by a set of line segments, half-lines, ... are s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Callitris Macleayana
''Callitris macleayana'' is a species of conifer in the family Cupressaceae, endemic to Australia. The tree is commonly known as stringybark pine, as well as brush cypress pine and Port Macquarie pine, although it does not belong to the pine genus or family. Stringybark pine is found in two regions of Australia's east coast, one in the centre and one in the north. Description ''Callitris macleayana'' is a large, straight-trunked tree with spreading branches and up to 40 metres in height. The bark is furrowed, and its juvenile leaves are around 1 cm in length, giving way to mature foliage of 2-3 mm; cones often occur in solitary on larger fruiting branches, and have 6 scales when borne on mature trees. Distribution and habitat Stringybark pine occurs over much of the central and northeast coast of Australia with an estimated range of 20,000 km2, although its range is divided in two with a 1500 km gap between the two occurrences. In the North, it is found in op ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Neocallitropsis Pancheri
''Callitris pancheri'' is a plant species of the family Cupressaceae. It is endemic to New Caledonia, where it occurs in small, scattered population along rivers. It used to be placed in its own genus ''Neocallitropsis'' but molecular phylogenetic analysis indicated that it was nested within ''Callitris''.Pye, M. G., P. A. Gadek, and K. J. Edwards (2003). Divergence, Diversity and Species of the Australasian Callitris (Cupressaceae) and Allied Genera : Evidence from ITS Sequence Data. Australian Systematic Botany 16: 505–14. It is an evergreen coniferous tree growing to tall. The leaves are awl-shaped, long, arranged in eight rows in alternating whorls of four; in overall appearance, the foliage is superficially similar to some species of ''Araucaria'', though they are only very distantly related. ''Callitris pancheri'' is dioecious, with separate male and female trees; the seed cones A conifer cone, or in formal botanical usage a strobilus, : strobili, is a seed-bearing ...

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] [Amazon] |

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] [Amazon] |

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] [Amazon] |

Callitris Drummondii
''Callitris drummondii'', or Drummond's cypress, is a species of conifer in the family Cupressaceae. It is found only in Western Australia.

Callitris Roei
''Callitris roei'', or Roe's cypress-pine, is a species of ''Callitris'' native to Australia, where it is endemic to southwestern Western Australia from Moora south to Albany and east to Cape Arid National Park.Farjon, A. (2005). ''Monograph of Cupressaceae and Sciadopitys''. Royal Botanic Gardens, Kew. It is an evergreen shrub or small tree growing to 5 m tall. The leaves are borne in decussate whorls of three, scale-like, 2–5 mm long and 1–1.5 mm broad; leaves on seedlings are longer and needle-like, not scale-like.

The pollen Pollen is a powdery substance produced by most types of flowers of seed plants for the purpose of sexual reproduction. It consists of pollen grains (highly reduced Gametophyte#Heterospory, microgametophytes), which produce male gametes (sperm ... cones are cylindrical, 3–6 mm long and ...
