Podocarp
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 uni ...

Nageia
''Nageia'' is a genus of conifers belonging to the podocarp family Podocarpaceae.Christopher N. Page. 1990. "Podocarpaceae" pages 332-346. In: Klaus Kubitzki (general editor); Karl U. Kramer and Peter S. Green (volume editors) ''The Families and Genera of Vascular Plants'' volume I. Springer-Verlag: Berlin;Heidelberg, Germany. ''Nageia'' includes evergreen shrubs and trees, from one to 54 meters in height. A 2009 treatment of the genus recognized five species.James E. Eckenwalder. 2009. ''Conifers of the World''. Timber Press: Portland, OR, USA. . Some authors consider ''Nageia formosensis'' to be a separate species from ''Nageia nagi'', thus recognizing six species. The podocarp genera have been reshuffled by various botanists. Most recently, several species formerly classed as ''Nageia'' were moved to the new genus ''Retrophyllum'', while ''Nageia falcata'' and ''Nageia mannii'' were moved to the new genus ''Afrocarpus''.

Afrocarpus
''Afrocarpus'' is a genus of conifers of the family Podocarpaceae. Two to six species are recognized. They are evergreen trees native to Africa. ''Afrocarpus'' was designated a genus in 1989, when several species formerly classified in ''Podocarpus'' and '' Nageia'' were reclassified.Christopher N. Page. 1989. "New and maintained genera in the conifer families Podocarpaceae and Pinaceae". ''Notes of the Royal Botanical Garden Edinburgh'' 45(2): 377-395. Taxonomy ''Afrocarpus gaussenii'' was based on a single specimen of a cultivated individual of ''Afrocarpus falcatus'' in Madagascar. Its distinctive features might have resulted from the conditions of its cultivation. No species of ''Afrocarpus'' is known to be native to Madagascar.James E. Eckenwalder. 2009. ''Conifers of the World''. Timber Press: Portland, OR, USA. . In a recent treatment of ''Afrocarpus'', only two species were recognized; ''A. dawei'', ''A. gracilior'', and ''A. usambarensis'' were sunk into ''A. falcatus' ...

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 (''Podocarp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antarctic Flora
Antarctic flora are a distinct community of vascular plants which evolved millions of years ago on the supercontinent of Gondwana. Presently, species of Antarctica flora reside on several now separated areas of the Southern Hemisphere, including southern South America, southernmost Africa, New Zealand, Australia, and New Caledonia. Joseph Dalton Hooker (1817 – 1911) was the first to notice similarities in the flora and speculated that Antarctica had served as either a source or a transitional point, and that land masses now separated might formerly have been adjacent. Based on the similarities in their flora, botanist Ronald D'Oyley Good identified a separate Antarctic Floristic Kingdom that included southern South America, New Zealand, and some southern island groups. In addition, Australia was determined to be its own floristic kingdom because of the influx of tropical Eurasian flora that had mostly supplanted the Antarctic flora and included New Guinea and New Caledonia in ...

Dacrydium
''Dacrydium'' is a genus of conifers belonging to the podocarp family Podocarpaceae. Sixteen species of evergreen dioecious trees and shrubs are presently recognized. The genus was first described by Solander in 1786, and formerly included many more species, which were divided into sections A, B, and C by Florin in 1931. The revisions of de Laubenfels and Quinn (see references), reclassified the former section A as the new genus '' Falcatifolium'', divided Section C into new genera '' Lepidothamnus, Lagarostrobos'' and ''Halocarpus'', and retained Section B as genus ''Dacrydium''. Species Distribution The natural range of ''Dacrydium'' extends from New Zealand, New Caledonia, Fiji and the Solomon Islands through Malesia (New Guinea, Indonesia, Malaysia and the Philippines), to Thailand and southern China China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's List of countries and dependencies by population, most populous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gymnosperm
The gymnosperms ( lit. revealed seeds) are a group of seed-producing plants that includes conifers, cycads, '' Ginkgo'', and gnetophytes, forming the clade Gymnospermae. The term ''gymnosperm'' comes from the composite word in el, γυμνόσπερμος ( el, γυμνός, translit=gymnos, lit=naked, label=none and el, σπέρμα, translit=sperma, lit=seed, label=none), literally meaning 'naked seeds'. The name is based on the unenclosed condition of their seeds (called ovules in their unfertilized state). The non-encased condition of their seeds contrasts with the seeds and ovules of flowering plants ( angiosperms), which are enclosed within an ovary. Gymnosperm seeds develop either on the surface of scales or leaves, which are often modified to form cones, or solitary as in yew, '' Torreya'', '' Ginkgo''. Gymnosperm lifecycles involve alternation of generations. They have a dominant diploid sporophyte phase and a reduced haploid gametophyte phase which is dep ...

Manoao
''Manoao'' is a Monotypic taxon, monotypic genus in the family ''Podocarpaceae.'' The single species, ''M. colensoi'', known as manoao (Māori language, Māori), silver pine, Westland, New Zealand, Westland pine, or white silver pine, is endemic (ecology), endemic to New Zealand. Before 1996 it was classified in genus ''Dacrydium'' or ''Lagarostrobos'', but has recently been recognised as a distinct genus; some botanists still treat it in ''Lagarostrobos'' on the basis that it is not phylogenetically distinct from that genus. In molecular phylogenetic analyses ''Manoao'' was found to be related to ''Parasitaxus'' (a parasitic and monotypic genus from New Caledonia) and ''Lagarostrobos'' (a single species from Tasmania when narrowly defined), but their exact relationships are unresolved. ''Manoao colensoi'' is a slow-growing evergreen tree up to in height, in shady, wet areas of New Zealand. It is a source of fine, straight and durable timber. Distribution ''M. colensoi'' ca ...

Sundacarpus
''Sundacarpus'' is a monotypic genus of conifers containing a single species ''Sundacarpus amarus'', belonging to the family Podocarpaceae. ''Sundacarpus'' was designated a genus by C.N.Page in 1989; formerly it had been classified variously as a species of ''Podocarpus'' or of '' Prumnopitys''. ''Sundacarpus amarus'' is a large evergreen tree, in height, with a trunk from in diameter. The leaves are long and narrow. ''Sundacarpus amarus'' is native to parts of Australia and Malesia. In Australia, the genus is found only in Queensland, primarily on the Atherton Tableland and adjacent parts of northeastern coastal Queensland. It is quite common in New Guinea, New Britain, and New Ireland, where they are often found in montane forests together with southern beech (''Nothofagus''). ''Sundacarpus amarus'' is also found on the Indonesian islands of Buru, Halmahera, Morotai, Sulawesi, Lombok, Flores, Timor, Sumbawa, Java, Sumatra, in Sabah province on the island of Borneo and on ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opin ...
