Cocoseae
Cocoseae is a tribe of cocosoid palms of the family Arecaceae. Description The fruit of the Cocoseae is a modified drupe, with a sclerenchymatous epicarp and a highly developed mesocarp, formed mainly by parenchyma . The endocarp is generally sclerenchymatous and protects the seeds from predation and drying. The most obvious synapomorphy In phylogenetics, an apomorphy (or derived trait) is a novel character or character state that has evolved from its ancestral form (or plesiomorphy). A synapomorphy is an apomorphy shared by two or more taxa and is therefore hypothesized to hav ... of the species of this tribe is the presence, in the endocarp, of three or more "eyes" or pores of germination. Distribution The Cocoseae are distributed mainly in the Neotropical regions, with two genera endemic to Africa (''Jubaeopsis'' and ''Elaeis'') and Madagascar ( ''Beccariophoenix'' and ''Voanioala'' ), respectively. Systematics The Cocoseae in the sense of Dransfield et al. (2008) are id ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allagoptera
''Allagoptera'' is a monoecious genus of flowering plant in the palm family found in South America consisting of 5 accepted species. Compared to other genera within the Cocoseae ''Allagoptera'' is described as particularly specialized.Uhl, Natalie W. and Dransfield, John (1987) ''Genera Palmarum - A classification of palms based on the work of Harold E. Moore''. Lawrence, Kansas: Allen Press. / The genus name is a Greek combination of "change" and "feather", describing the full leaf; it was formerly named ''Diplothemium''. Description ''Allagoptera'' produces very short or acaulescent trunks and in cases where the trunk grows erect it often makes a downward turn leaving the crown below the trunk-base. The trunks in ''Allagoptera'' are among the few in the palm family which tend to bifurcate, producing multiple heads per unit. The pinnate leaves are gently arching to 2 m and are carried on long, slender petioles which are adaxially channeled. The single-fold leaflets are regul ...

Beccariophoenix
''Beccariophoenix'' is a genus of three species of Arecaceae (palms), native to Madagascar. The genus is closely related to the '' Cocos'', or coconut genus, and notably '' Beccariophoenix alfredii'' is similar in appearance to the coconut palm. It was named after Odoardo Beccari (1843-1920). Description Palms in this group have solitary trunks. Crownshafts are not present in the genus; the leaves are pinnate Pinnation (also called pennation) is the arrangement of feather-like or multi-divided features arising from both sides of a common axis. Pinnation occurs in biological morphology, in crystals, such as some forms of ice or metal crystals, an ..., to 2–5 m long. The term "windowpane" palm comes from the leaflets on younger plants that are only partially divided from each other, where there appear to be 'windows' in the leaves between the leaflets. Older specimens do not display the windowpanes as the leaflets completely divide from each other. They are somewhat co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beccariophoenix Alfredii
''Beccariophoenix alfredii'', also known as the high plateau coconut palm, is a recently discovered species of Arecaceae (palms), endemic to Madagascar. It is in the genus ''Beccariophoenix'', and is closely related to the genus '' Cocos''. ''Beccariophoenix alfredii'' is very similar in appearance to the coconut palm, although somewhat cold hardy, making it a good look-alike for the coconut in cooler climates. Description ''Beccariophoenix alfredii'' grows up to in height with a trunk up to in diameter. The trunk is unarmed and bare, with closely ringed leaf scars. The crown holds 30–36 pinnate leaves, which reach lengths of . Each leaf holds approximately 120 pairs of leaflets. The leaflets are very slender and crowded at the base, and are either rigid or somewhat pendulous. Towards the base of the leaf, leaflets are about long and wide. Mid-leaf leaflets are at their largest, being about long and wide. At the tip of the leaf, leaflets become smaller again, being ...

Beccariophoenix Madagascariensis
''Beccariophoenix madagascariensis'', commonly known as the coastal beccariophoenix, is a species of flowering plant in the family Arecaceae. It is a large Coconut relative that is vulnerable in its habitat in Madagascar. Range and habitat ''Beccariophoenix madagascariensis'' is native to Madagascar's eastern rainforests, between Tolagnaro and Mantadia. It is found in humid lowland forest and mid-elevation humid montane forest from sea level to 1,200 meters elevation. It is found in forests with a slightly open canopy, typically on poor soils derived from white sand or on podzol In soil science, podzols are the typical soils of coniferous or boreal forests and also the typical soils of eucalypt forests and heathlands in southern Australia. In Western Europe, podzols develop on heathland, which is often a construct of hum ...ized ridge tops. There are only three known populations, which are severely fragmented. There are an estimated 900 mature individual trees. Similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beccariophoenix Fenestralis
''Beccariophoenix fenestralis'' is a species of plant in the family Arecaceae. It was described as a species distinct from '' Beccariophoenix madagascariensis'' in 2014. Description ''Beccariophoenix fenestralis'' is a palm tree which grows about 10 meters tall. It differs from ''B. madagascariensis'' when a seedling, in having wide, mostly unsplit leaves, whereas the ''B. madagascariensis'' has fully split, very stiff upright leaves when young. Range and habitat ''Beccariophoenix fenestralis'' is known from a single location in Brickaville, Atsinanana region, growing in humid lowland forest at 140 meters elevation. Conservation and threats There is only one known population of the species, with an area of occupancy Area is the quantity that expresses the extent of a region on the plane or on a curved surface. The area of a plane region or ''plane area'' refers to the area of a shape or planar lamina, while ''surface area'' refers to the area of an open ... (AOO) of ...

Allagoptera Arenaria
''Allagoptera arenaria'', popularly known as seashore palm, is a fruit tree native to the Atlantic Coast of Brazil. It grows in coastal strand, just above the high tide mark, and is widely cultivated as an ornamental throughout South America. ''Allagoptera arenaria'' is relatively short, reaching about tall. The plant is monoecious, with male and female plants in distinct spirals in the same spike. The leaves emerge right out of the ground from a subterranean trunk that is rarely visible, and grow in a swirling pattern, spreading out on different and seemingly random planes. There are 6–15 bright green to silvery green pinnately compound (feather-like) leaves long, with each leaflet about long. Its fruits are yellowish green and shaped like small coconuts, about long and in diameter. Etymology The generic name of the seashore palm, ''Allogoptera'', comes from the Ancient Greek words ('), meaning change, and ('), meaning wing, and refers to the swirled, changing pattern ...

Arecaceae
The Arecaceae is a family of perennial flowering plants in the monocot order Arecales. Their growth form can be climbers, shrubs, tree-like and stemless plants, all commonly known as palms. Those having a tree-like form are called palm trees. Currently, 181 genera with around 2,600 species are known, most of which are restricted to tropical and subtropical climates. Most palms are distinguished by their large, compound, evergreen leaves, known as fronds, arranged at the top of an unbranched stem. However, palms exhibit an enormous diversity in physical characteristics and inhabit nearly every type of habitat within their range, from rainforests to deserts. Palms are among the best known and most extensively cultivated plant families. They have been important to humans throughout much of history. Many common products and foods are derived from palms. In contemporary times, palms are also widely used in landscaping. In many historical cultures, because of their imp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
