Podocarps
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 ...

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'' ...

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 ...

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 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] |

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.

Phyllocladaceae
''Phyllocladus'', the celery pines, is a small genus of conifers, now usually treated in the family Podocarpaceae.James E. Eckenwalder. 2009. ''Conifers of the World''. Timber Press: Portland, OR, USA. .'' ''Species occur mainly in New Zealand, Tasmania, and Malesia in the Southern Hemisphere, though '' P. hypophyllus ''ranges into the Philippines, a short way north of the equator. Characteristics They are small to medium-sized trees, reaching 10–30 m tall, or sometimes small shrubs. The main structural shoots are green for 2–3 years, then turn brown as the bark thickens. The leaves are sparse, tiny, scale-like, 2–3 mm long, and only green (photosynthetic) for a short time, soon turning brown. Most photosynthesis is performed by highly modified, leaf-like short shoots called phylloclades; these develop in the axils of the scale leaves, and are simple or compound (depending on species). Simple phylloclades are rhombic, 2–5 cm long, and compound phylloclades are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sensu Stricto
''Sensu'' is a Latin word meaning "in the sense of". It is used in a number of fields including biology, geology, linguistics, semiotics, and law. Commonly it refers to how strictly or loosely an expression is used in describing any particular concept, but it also appears in expressions that indicate the convention or context of the usage. Common qualifiers ''Sensu'' is the ablative case of the noun ''sensus'', here meaning "sense". It is often accompanied by an adjective (in the same case). Three such phrases are: *''sensu stricto'' – "in the strict sense", abbreviation ''s.s.'' or ''s.str.''; *''sensu lato'' – "in the broad sense", abbreviation ''s.l.''; *''sensu amplo'' – "in a relaxed, generous (or 'ample') sense", a similar meaning to ''sensu lato''. Søren Kierkegaard uses the phrase ''sensu eminenti'' to mean "in the pre-eminent r most important or significantsense". When appropriate, comparative and superlative adjectives may also be used to convey the meaning o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sister Taxon
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxonomi ...

Falcatifolium Taxoides
''Falcatifolium taxoides'' is a species of conifer in the family Podocarpaceae. It is found only in New Caledonia, and is the only known host of its non-photosynthetic, possibly parasitic relative, ''Parasitaxus usta''. Etymology ''Falcatifolium'' means 'with sickle-shaped leaves', while ''taxoides'' means 'yew-like' (resembling ''Taxus ''Taxus'' is a genus of coniferous trees or shrubs known as yews in the family Taxaceae.
