Podocarpus
''Podocarpus'' () is a genus of conifers, the most numerous and widely distributed of the podocarp family, the Podocarpaceae. The name comes from Greek πούς (poús, “foot”) + καρπός (karpós, “fruit”). ''Podocarpus'' species are evergreen shrubs or trees, usually from tall, known to reach 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.Earle, Chris J.''Podocarpus''.The Gymnosperm Database. 2013. Species are cultivated as ornamental plants for parks and large gardens. The cultivar 'County Park Fire' has won the Royal Horticultural Society's Award of Garden Merit. Names and etymology Common names for various species include "yellowwood" and "pine", as in the plum pine (''Podocarpu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Podocarpus Elatus
''Podocarpus elatus'', known as the plum pine, the brown pine or the Illawarra plum, is a species of ''Podocarpus'' endemic to the east coast of Australia, in eastern New South Wales and eastern Queensland. It is a medium to large evergreen tree growing to 30–36 m tall with a trunk up to 1.5 m diameter. The leaves are lanceolate, 5–15 cm long (to 25 cm long on vigorous young trees) and 6–18 mm broad. The seed cones are dark blue-purple, berry-like, with a fleshy base 2-2.5 cm diameter bearing a single oval or globose seed 1 cm in diameter. Uses The fleshy part of the seed cone is edible, used in condiments. The timber was prized for furniture, joinery, boat planking, lining and piles in salt water. Podocarpus elatus is an attractive ornamental tree. In older Australian suburbs, the plum pine is used as an ornamental street tree, such as at Baldry Street, Chatswood.Willoughby City Council, Urban Tree Management Policy, Volume 3, Street Tree Master P ...

Podocarpus Macrophyllus
''Podocarpus macrophyllus'' is a conifer in the genus ''Podocarpus'', family Podocarpaceae. It is the northernmost species of the genus, native to southern Japan and southern and eastern China. Common names in English include yew plum pine, Buddhist pine, fern pine and Japanese yew. and are Japanese names for this tree. In China, it is known as ''luóhàn sōng'' (), which literally means "arhat pine". Description It is a small to medium-sized evergreen tree, reaching tall. The leaves are strap-shaped, long, and about 1 cm broad, with a central midrib. The cones are borne on a short stem, and have two to four scales, usually only one (sometimes two) fertile, each fertile scale bearing a single apical seed 10–15 mm. When mature, the scales swell up and become reddish purple, fleshy, and berry-like, 10–20 mm long; they are then eaten by birds, which disperse the seeds in their droppings. ''P. macrophyllus'' occurs in forests, open thickets, and roadsides fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Podocarpus Totara
''Podocarpus totara'' (; from the Maori-language ; the spelling "totara" is also common in English) is a species of podocarp tree endemic to New Zealand. It grows throughout the North Island and northeastern South Island in lowland, montane and lower subalpine forest at elevations of up to 600 m. Tōtara is commonly found in lowland areas where the soil is fertile and well drained. Description The tōtara is a medium to large tree, which grows slowly to around 20 to 25 m, exceptionally to 35 m; it is noted for its longevity and the great girth of its trunk. The bark peels off in papery flakes, with a purplish to golden brown hue. The sharp, dull-green, needle-like leaves are stiff and leathery, 2 cm long. This plant produces highly modified cones with two to four fused, fleshy, berry-like, juicy scales, bright red when mature. The cone contains one or two rounded seeds at the apex of the scales. The largest known living tōtara, the Pouakani Tree, near Pureora in the ce ... [...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 19 genera if ''Phyllocladus'' is included and ''Manoao'' and ''Sundacarpus'' are recognized. The family is a classic member of the Antarctic flora, with its main centres of diversity in 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 China and southern India. Two genera also occur in sub-Saharan Africa, the widespread ''Podocarpus'' and the endemic '' Afrocarpus''. ''Parasitaxus usta'' is uniqu ...

Podocarpus Henkelii
''Podocarpus henkelii'' (Henkel's yellowwood, af, Henkel-se-Geelhout, xh, Umsonti, zu, Umsonti) is a South African species of conifer in the family Podocarpaceae. It is grown ornamentally in gardens for its strikingly neat, attractive form and its elegant, drooping foliage. Description An attractive ornamental tree, this is one of the most recognisable of the yellowwoods. It can easily be distinguished from its close relatives by its long, slender, drooping leaves. It has a straight, well-formed trunk and naturally assumes a pyramid-shape as it grows, eventually becoming very tall (30m). Like all yellowwoods, this tree is dioecious, with separate male and female trees. As conifers they produce cones, although it is their fruit-like seeds that are most prominent. These seeds are eaten and distributed by birds. The fleshy coating of the seed contains a germination inhibitor so being eaten actually helps germination by removing this coating. Distribution Henkel's yellowwood is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Podocarpus Neriifolius
''Podocarpus neriifolius'' is a species of conifer in the family Podocarpaceae. It grows 10–15m tall, though very occasionally taller, in tropical and subtropical wet closed forests, between 650m and 1600m altitude.Dy Phon Pauline, 2000, ''Plants Used In Cambodia'', printed by Imprimiere Olympic, Phnom Penh In Cambodia however it grows in a dwarf form some 2–4m tall, at Bokor, some 1000m elevation.

Gondwana
Gondwana () was a large landmass, often referred to as a supercontinent, that formed during the late Neoproterozoic (about 550 million years ago) and began to break up during the Jurassic period (about 180 million years ago). The final stages of break-up, involving the separation of Antarctica from South America (forming the Drake Passage) and Australia, occurred during the Paleogene. Gondwana was not considered a supercontinent by the earliest definition, since the landmasses of Baltica, Laurentia, and Siberia were separated from it. To differentiate it from the Indian region of the same name (see ), it is also commonly called Gondwanaland. Gondwana was formed by the accretion of several cratons. Eventually, Gondwana became the largest piece of continental crust of the Palaeozoic Era, covering an area of about , about one-fifth of the Earth's surface. During the Carboniferous Period, it merged with Laurasia to form a larger supercontinent called Pangaea. Gondwana (and Pan ...

Conifer Cone
A conifer cone (in formal botany, botanical usage: strobilus, plural strobili) is a seed-bearing organ on gymnosperm plants. It is usually woody, ovoid to globular, including scales and bracts arranged around a central axis, especially in conifers and cycads. The cone of Pinophyta (conifer clade) contains the plant sexuality, reproductive structures. The woody cone is the female cone, which produces seeds. The male cone, which produces pollen, is usually herbaceous plant, herbaceous and much less conspicuous even at full maturity. The name "cone" derives from Greek ''konos'' (pine cone), which also gave name to the cone (geometry), geometric cone. The individual plates of a cone are known as ''scales''. The ''umbo'' of a conifer cone refers to 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. The male cone (microstrobilus or pollen cone) is structurally similar across all conifers, differing only in small wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pollen
Pollen is a powdery substance produced by seed plants. It consists of pollen grains (highly reduced microgametophytes), which produce male gametes (sperm cells). Pollen grains have a hard coat made of sporopollenin that protects the gametophytes during the process of their movement from the stamens to the pistil of flowering plants, or from the male cone to the female cone of gymnosperms. If pollen lands on a compatible pistil or female cone, it germinates, producing a pollen tube that transfers the sperm to the ovule containing the female gametophyte. Individual pollen grains are small enough to require magnification to see detail. The study of pollen is called palynology and is highly useful in paleoecology, paleontology, archaeology, and forensics. Pollen in plants is used for transferring haploid male genetic material from the anther of a single flower to the stigma of another in cross-pollination. In a case of self-pollination, this process takes place from the anth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Evergreen
In botany, an evergreen is a plant which has foliage that remains green and functional through more than one growing season. This also pertains to plants that retain their foliage only in warm climates, and contrasts with deciduous plants, which completely lose their foliage during the winter or dry season. Evergreen species There are many different kinds of evergreen plants, both trees and shrubs. Evergreens include: *Most species of conifers (e.g., pine, hemlock, blue spruce, and red cedar), but not all (e.g., larch) *Live oak, holly, and "ancient" gymnosperms such as cycads *Most angiosperms from frost-free climates, and rainforest trees *All Eucalypts * Clubmosses and relatives *Bamboos The Latin binomial term , meaning "always green", refers to the evergreen nature of the plant, for instance :'' Cupressus sempervirens'' (a cypress) :''Lonicera sempervirens'' (a honeysuckle) :''Sequoia sempervirens'' (a sequoia) Leaf longevity in evergreen plants varies from a few months ...

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, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a 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 reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typically ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
