Podocarpaceae (Dacrydium Beccarii) (15742645126)
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 ...

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] |

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.

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 dependent on ...

Parasitic Plant
A parasitic plant is a plant that derives some or all of its nutritional requirements from another living plant. They make up about 1% of angiosperms and are found in almost every biome. All parasitic plants develop a specialized organ called the haustorium, which penetrates the host plant, connecting them to the host vasculature – either the xylem, phloem, or both. For example, plants like ''Striga'' or ''Rhinanthus'' connect only to the xylem, via xylem bridges (xylem-feeding). Alternately, plants like ''Cuscuta'' and some members of ''Orobanche'' connect to both the xylem and phloem of the host. This provides them with the ability to extract water and nutrients from the host. Parasitic plants are classified depending on the location where the parasitic plant latches onto the host (root or stem), the amount of nutrients it requires, and their photosynthetic capability. Some parasitic plants can locate their host plants by detecting volatile chemicals in the air or soil given ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parasitaxus Usta
''Parasitaxus usta'' is a rare species of conifer of the family Podocarpaceae, and the sole species of the genus ''Parasitaxus''. It is a woody shrub up to 1.8 m found only in the remote, densely forested areas of New Caledonia, first discovered and described by Vieillard in 1861. It is generally mentioned that ''Parasitaxus usta'' is the only known parasitic gymnosperm. The species remarkably lacks roots and is always found attached to the roots of ''Falcatifolium taxoides'' (another member of the Podocarpaceae). However, the question is still left open, as the plant is in any case not a haustorial parasite, which is usually the case with angiosperms. Certain experts therefore consider the plant as a myco-heterotroph. Molecular phylogenetic analysis also suggest affinities between ''Parasitaxus'' and the genera ''Manoao'' (New Zealand) and ''Lagarostrobos'' (Tasmania). Parasitaxus has been shown to contain high levels of chlorophyll. However, a genome analysis shows that man ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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'' ...
