Borassus
''Borassus'' (palmyra palm) is a genus of five species of fan palms, native to tropical regions of Africa, Asia and Papua New Guinea. Description These massive palms can grow up to high and have robust trunks with distinct leaf scars; in some species the trunk develops a distinct swelling just below the crown, though for unknown reasons. The leaves are fan-shaped, long and with spines along the petiole margins (no spines in ''B. heineanus''). The leaf sheath has a distinct cleft at its base, through which the inflorescences appear; old leaf sheaths are retained on the trunk, but fall away with time. All ''Borassus'' palms are dioecious, with male and female flowers on separate plants; male flowers are less than long and in semi-circular clusters, sandwiched between leathery bracts in pendulous catkins; female flowers are wide, globe-shaped and solitary, sitting directly on the surface of the inflorescence axis. The fruits are wide, roughly spherical and each contain 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Borassus Flabellifer
''Borassus flabellifer'', commonly known as doub palm, palmyra palm, tala or tal palm, toddy palm, wine palm or ice apple, is native to South Asia (especially in Bangladesh & South India) and Southeast Asia. It is reportedly naturalized in Socotra and parts of China. Description ''Borassus flabellifer'' is a robust tree and can reach a height of . The trunk is grey, robust and ringed with leaf scars; old leaves remain attached to the trunk for several years before falling cleanly. The leaves are fan-shaped and long, with robust black teeth on the petiole margins. Like all ''Borassus'' species, ''B. flabellifer'' is dioecious with male and female flowers on separate plants. The male flowers are less than long and form semi-circular clusters, which are hidden beneath scale-like bracts within the catkin-like inflorescences. In contrast, the female flowers are golfball-sized and solitary, sitting upon the surface of the inflorescence axis. After pollination, these blooms develop i ...

Borassus Aethiopum
''Borassus aethiopum'' is a species of '' Borassus'' palm from Africa. In English it is variously referred to as African fan palm, African palmyra palm, deleb palm, ron palm, toddy palm, black rhun palm, rônier palm (from the French). It is widespread across much of tropical Africa from Senegal to Ethiopia and south to northern South Africa, though it is largely absent from the forested areas of Central Africa and desert regions such as the Sahara and Namib. This palm also grows in northwest Madagascar and the Comoros. Description The typical form of ''Borassus aethiopum'' is a solitary palm to in height and in diameter at the base. In the river bottoms (floodplains) of many East African rivers (the Rufiji in Tanzania and the Tana in Kenya among others) a closely related form can be up to seven feet (2.1 meters) thick at breast height (4 feet (1.2 meters) above ground) and having the same thickness in its upper ventricosity. It also has a height of up to 100 feet ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Borassus Akeassii
''Borassus akeassii'' is a species of palmyra palm which is native to west and central Africa. It occurs from Senegal to Congo-Kinshasa.

Borassus Heineanus
''Borassus heineanus'' is a species of a large solitary fan palm found only in northern New Guinea, in both Papua New Guinea and Indonesia, where it is threatened by habitat loss. Also known as the New Guinea palmyra palm, ''B. heineanus'' grows up to 20 m tall with a robust trunk ringed with leaf scars; the old leaves remain attached to the trunk, but eventually fall cleanly. The blueish-green leaves are deeply dissected, up to 3.2 m across and the petioles have very sharp edges, which can give a nasty cut to the unwary. As with all ''Borassus'' species, ''B. heineanus'' is dioecious with male and female flowers on separate trees. The male flowers are 1.5 cm long and in semi-circular clusters enclosed within leathery bracts, forming massive catkin-like inflorescences. In contrast, the female flowers are golfball-sized, solitary and rest on the surface of the inflorescence axis. After pollination, they develop into green fleshy fruits, each containing 1-3 seeds.

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 importance as ...

Leaf
A leaf ( : leaves) is any of the principal appendages of a vascular plant stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. Most leaves are flattened and have distinct upper (adaxial) and lower ( abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax and other features. Leaves are mostly green in color due to the presence of a compound called chlorophyll that is essential for photosynthesis as it absorbs light ...

Savanna
A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. According to '' Britannica'', there exists four savanna forms; ''savanna woodland'' where trees and shrubs form a light canopy, ''tree savanna'' with scattered trees and shrubs, ''shrub savanna'' with distributed shrubs, and ''grass savanna'' where trees and shrubs are mostly nonexistent.Smith, Jeremy M.B.. "savanna". Encyclopedia Britannica, 5 Sep. 2016, https://www.britannica.com/science/savanna/Environment. Accessed 17 September 2022. Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in for ...

Fan Palm
Fan palm as a descriptive term can refer to any of several different kinds of palms ( Arecaceae) in various genera with leaves that are palmately lobed (rather than pinnately compound). Most are members of the subfamily Coryphoideae, though a few genera in subfamily Calamoideae (''Mauritia'', ''Mauritiella'' and ''Lepidocaryum'') also have palmate leaves. Fan palm genera include: * '' Bismarckia'' * '' Borassus'' * ''Coccothrinax'' * ''Copernicia'' * ''Hyphaene'' * ''Licuala'' * '' Pritchardia'' * ''Rhapidophyllum'' * ''Rhapis'' * ''Sabal'' * ''Thrinax'' * ''Trachycarpus'' * '' Trithrinax'' Fan palm can also be used as part of the common name of particular genera or species. Among the palms commonly known as fan palms are: * ''Chamaerops humilis'' (European fan palm) * ''Hyphaene petersiana'' (Real fan palm) * ''Livistona'' (Chinese fan palm and others) * ''Washingtonia'' (California fan palm, Mexican fan palm) * ''Latania'' (Indian Ocean fan palms) The travellers palm (''Rav ...
