Encephalartos Chimanimaniensis
The Chimanimani cycad (''Encephalartos chimanimaniensis'') is a species of cycad that is endemic to the Chimanimani Mountains of eastern Zimbabwe. It is a threatened species which has been locally extirpated by cycad collectors. Description These plants have an erect stem, without branches, but often with secondary stems that develop from basal suckers, up to 1.8 meters high and with 45 cm of diameter. The leaves, pinnate, 100–150 cm long, are composed of lanceolate leaflets, with margins endowed with small spines, 12–18 cm long and arranged on the rachis at 45-80°. It is a dioecious species, with 1-3 ovoid male cones, sessile, green in color, 50–70 cm long and 8–10 cm in diameter, with large, rhombic-shaped microsporophylls. The female cones, solitary, have a yellow-green color, are 35–40 cm long and 20–23 cm broad, with macrosporophylls with a warty surface. The seeds have an oblong shape, are 20–30 mm long, 15–20 cm wide and are covered with a red sarcotesta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cycad
Cycads are seed plants that typically have a stout and woody (ligneous) trunk (botany), trunk with a crown (botany), crown of large, hard, stiff, evergreen and (usually) pinnate leaves. The species are dioecious, that is, individual plants of a species are either male or female. Cycads vary in size from having trunks only a few centimeters to several meters tall. They typically grow very slowly and live very long. Because of their superficial resemblance, they are sometimes mistaken for Arecaceae, palms or ferns, but they are not closely related to either group. Cycads are gymnosperms (naked-seeded), meaning their fertilization, unfertilized seeds are open to the air to be directly fertilized by pollination, as contrasted with angiosperms, which have enclosed seeds with more complex fertilization arrangements. Cycads have very specialized pollinators, usually a specific species of beetle. Both male and female cycads bear cones (strobilus, strobili), somewhat similar to conife ...

Chimanimani Mountains
The Chimanimani Mountains are a mountain range on the border of Zimbabwe and Mozambique. The mountains are in the southern portion of the Eastern Highlands, or Manica Highlands, a belt of highlands that extend north and south along the international border, between the Zambezi and Save rivers. The Chimanimani Mountains include Monte Binga (2,436 m), the highest peak in Mozambique and the second-highest in Zimbabwe. The mountains are home to diverse forests, savannas, montane grasslands, and heathlands. Zimbabwe's Chimanimani National Park and Mozambique's adjacent Chimanimani National Reserve protect parts of the range. These two parks, together with a larger buffer zone, constitute Chimanmani Transfrontier Conservation Area.Timberlake, J.R., Darbyshire, I., Wursten, B., Hadj-Hammou, J., Ballings, P., Mapaura, A., Matimele, H., Banze, A., Chipanga, H., Muassinar, D., Massunde, M., Chelene, I., Osborne, J. & Shah, T.

Zimbabwe
Zimbabwe (), officially the Republic of Zimbabwe, is a landlocked country located in Southeast Africa, between the Zambezi and Limpopo Rivers, bordered by South Africa to the south, Botswana to the south-west, Zambia to the north, and Mozambique to the east. The capital and largest city is Harare. The second largest city is Bulawayo. A country of roughly 15 million people, Zimbabwe has 16 official languages, with English, Shona language, Shona, and Northern Ndebele language, Ndebele the most common. Beginning in the 9th century, during its late Iron Age, the Bantu peoples, Bantu people (who would become the ethnic Shona people, Shona) built the city-state of Great Zimbabwe which became one of the major African trade centres by the 11th century, controlling the gold, ivory and copper trades with the Swahili coast, which were connected to Arab and Indian states. By the mid 15th century, the city-state had been abandoned. From there, the Kingdom of Zimbabwe was established, fol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sarcotesta
The sarcotesta is a fleshy seedcoat, a type of testa. Examples of seeds with a sarcotesta are pomegranate and some cycad seeds. The sarcotesta of pomegranate seeds consists of epidermal cells derived from the integument, and there are no aril An aril (pronounced ), also called an arillus, is a specialized outgrowth from a seed that partly or completely covers the seed. An arillode or false aril is sometimes distinguished: whereas an aril grows from the attachment point of the see ...s on these seeds.
