Afrocarpus Gracilior
''Afrocarpus gracilior'' (syn. ''Podocarpus gracilior'') is a species of coniferous tree in the family Podocarpaceae known as benet in Marakwet and East African yellowwood, African fern tree, or bastard yellowwood in English It is native to eastern Africa, in Ethiopia, Kenya, Tanzania, and Uganda, in Afromontane habitats. This is a common species found in many types of tropical mountain forest habitat. It is a dominant species in some areas. Nevertheless, it may be in slow decline due to deforestation and logging. Description ''Afrocarpus gracilior'' is a medium-sized tree, growing 20–40 m tall, rarely to 50 m, with a trunk diameter of 50–80 cm. The leaves are spirally arranged, lanceolate, 2–6 cm long and 3–5 mm broad on mature trees, larger, to long and 6 mm broad on vigorous young trees. The seed cones are highly modified, with a single diameter seed with a thin fleshy coating borne on a short peduncle. The mature seed is purple, and is dis ...

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] |
Ornamental Tree
Ornamental plants or garden plants are plants that are primarily grown for their beauty but also for qualities such as scent or how they shape physical space. Many flowering plants and garden varieties tend to be specially bred cultivars that improve on the original species in qualities such as color, shape, scent, and long-lasting blooms. There are many examples of fine ornamental plants that can provide height, privacy, and beauty for any garden. These ornamental perennial plants have seeds that allow them to reproduce. One of the beauties of ornamental grasses is that they are very versatile and low maintenance. Almost any types of plant have ornamental varieties: trees, shrubs, climbers, grasses, succulents. aquatic plants, herbaceous perennials and annual plants. Non-botanical classifications include houseplants, bedding plants, hedges, plants for cut flowers and foliage plants. The cultivation of ornamental plants comes under floriculture and tree nurseries, which is a ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plantation
A plantation is an agricultural estate, generally centered on a plantation house, meant for farming that specializes in cash crops, usually mainly planted with a single crop, with perhaps ancillary areas for vegetables for eating and so on. The crops that are grown include cotton, coffee, tea, cocoa, sugar cane, opium, sisal, oil seeds, oil palms, fruits, rubber trees and forest trees. Protectionist policies and natural comparative advantage have sometimes contributed to determining where plantations are located. In modern use the term is usually taken to refer only to large-scale estates, but in earlier periods, before about 1800, it was the usual term for a farm of any size in the southern parts of British North America, with, as Noah Webster noted, "farm" becoming the usual term from about Maryland northwards. It was used in most British colonies, but very rarely in the United Kingdom itself in this sense. There, as also in America, it was used mainly for tree plantations, a ...

Timber
Lumber is wood that has been processed into dimensional lumber, including beams and planks or boards, a stage in the process of wood production. Lumber is mainly used for construction framing, as well as finishing (floors, wall panels, window frames). Lumber has many uses beyond home building. Lumber is sometimes referred to as timber as an archaic term and still in England, while in most parts of the world (especially the United States and Canada) the term timber refers specifically to unprocessed wood fiber, such as cut logs or standing trees that have yet to be cut. Lumber may be supplied either rough- sawn, or surfaced on one or more of its faces. Beside pulpwood, ''rough lumber'' is the raw material for furniture-making, and manufacture of other items requiring cutting and shaping. It is available in many species, including hardwoods and softwoods, such as white pine and red pine, because of their low cost. ''Finished lumber'' is supplied in standard sizes, mostly ...

Afrocarpus Dawei
''Afrocarpus dawei'' is a species of conifer in the family Podocarpaceae. It is native to Africa, where it occurs in the Democratic Republic of the Congo, Tanzania, and Uganda. This species is a tree that grows in swampy forest habitat that is flooded in the rainy season. It is associated with '' Baikiaea insignis'' and ''Mimusops'' species. ''A. dawei'' is found in the Minziro Forest of Tanzania and the adjacent Sango Bay forests of Uganda, located west of Lake Victoria.

Afrocarpus Mannii
''Afrocarpus mannii'' is an evergreen coniferous tree native to the Afromontane forests of São Tomé Island in the Gulf of Guinea, growing at altitudes of 1,300 m up to the summit at 2,024 m. It was formerly classified as ''Podocarpus mannii''. It is a small tree, growing 10–15 m tall.

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 (''Podocarpu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
