Palmyra Palm
''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, 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 semicircular 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 and roughly spherical, and each contains ... [...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, lontar palm, wine palm, or ice apple, is a fan palm native to South Asia (especially in Bangladesh, East India, and South India) and Southeast Asia. It is reportedly naturalized in Socotra. 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 (botany), petiole margins. Like all ''Borassus'' species, ''B. flabellifer'' is Dioecy (plant), dioecious with male and female flowers on separate plants. But very rarely male and female flowers in same trees have also been noticed 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Germination
Germination is the process by which an organism grows from a seed or spore. The term is applied to the sprouting of a seedling from a seed of an angiosperm or gymnosperm, the growth of a sporeling from a spore, such as the spores of fungi, ferns, bacteria, and the growth of the pollen tube from the pollen grain of a seed plant. Seed plants Germination is usually the growth of a plant contained within a seed resulting in the formation of the seedling. It is also the process of reactivation of metabolic machinery of the seed resulting in the emergence of radicle and plumule. The seed of a vascular plant is a small package produced in a fruit or cone after the union of male and female reproductive cells. All fully developed seeds contain an embryo and, in most plant species some store of food reserves, wrapped in a seed coat. Dormant seeds are viable seeds that do not germinate because they require specific internal or environmental stimuli to resume growth. Und ...

Borassus Madagascariensis
''Borassus madagascariensis'' is a species in the palm family Arecales endemic to Madagascar.Jumelle, Henri Lucien & Perrier de la Bâthie, Joseph Marie Henry Alfred. 1907.

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. Each seed is ... [...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. It was first described in 2006, having previously been confused with '' Borassus aethiopum'' and ''Borassus flabellifer''. It is used by local people for a variety of purposes, particularly sap extraction. Description This palm reaches impressive height of 15 meters, typically developing a noticeably swollen trunk that may bear numerous irregular scars, often a result of external influences. The crown consists of a moderate to dense number of glaucous, fan-shaped leaves, each supported by a sturdy petiole with either serrated black teeth along the edges or, in some cases, nearly smooth margins. The leaf blade is relatively flat, divided into numerous rigid leaflets with pointed tips that may split over time. Fine, persistent hairs can sometimes be found along the ribs of younger leaves, gradually fading as they mature. The adaxial hastula ...

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 thick at breast height ( above ground) and having the same thickness in its upper ventricosity. It also has a height of up to . The fan-shaped leaves are wide (larger, to in the bottomla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
