Stangeria Eriopus
''Stangeria eriopus'' is a cycad endemic to southern Africa. It is the sole species in the genus ''Stangeria'', most closely related to the Australian genus ''Bowenia'', with which it forms the family Stangeriaceae. Description ''Stangeria eriopus'' is a very long-lived, perennial, evergreen cycad. The stalked, feathered, fern-like leaves are between 25 centimeters and two meters long, with the petiole comprising one third to one half of the overall length (in both varieties). They are pinnately-veined, which distinguishes the species from all other cycads. The petiole comprises half the length of the leaf. The young leaves are bent in bud position, the tip appears rolled up. Young leaves are dotted with short, gray hairs (trichomes), which usually fall off quickly and only stick to the petiole. These trichomes are unbranched and transparent or colored. The species occurs as two variable forms or varieties. The forest form, growing in regions with higher rainfall, is characterize ...

Maputaland Coastal Forest Mosaic
The Maputaland coastal forest mosaic is a subtropical moist broadleaf forest ecoregion on the Indian Ocean coast of Southern Africa. It covers an area of in southern Mozambique, Eswatini, and the KwaZulu-Natal Province of South Africa. Mozambique's capital Maputo lies within the ecoregion. Geography The Maputaland coastal forest mosaic occupies the humid coastal strip along the Indian Ocean, inland to the Lebombo Mountains for much of its length. This is part of a strip of moist coastal forests that extend along Africa's Indian Ocean coast from southern Somalia to South Africa. The northern limit of the ecoregion is north of the mouth of the Limpopo River, near Xai-Xai in Mozambique, where the forests transition to the Southern Zanzibar-Inhambane coastal forest mosaic. The southern limit is near the St Lucia estuary in KwaZulu-Natal, where the Maputaland forests transition to the Kwazulu-Cape coastal forest mosaic. Climate The ecoregion has a seasonally moist, tropical to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Stanger (surveyor)
William Stanger (27 September 1811 in Tydd St. Mary, Wisbech – 14 March 1854 in Durban) was best known as a surveyor-general in South Africa, but was also a geologist, botanist and medical doctor. He was the son of Willam Stanger and Mary Dent. He studied medicine and natural science at Edinburgh University, and after returning from a trip to Australia and New Zealand, ran a practice in London for some time. William Stanger took part as geologist and doctor in the ill-fated 1841 British expedition to the Niger. Three vessels steamed about 320 miles up the Niger and Chadda. Treaties were signed with the two black Princes of Eboe and Iddah, agreeing to the abolition of the slave trade and of human sacrifices, and the signatories were then left to resume their normal practices. An extract from a letter written on board the "''Æthiope''" on 21 October 1841 - ''"We entered the Nun on the 10th inst., and proceeded up the river the next morning, and fell in with the "Albert" on t ...

Greek Language
Greek ( el, label=Modern Greek, Ελληνικά, Elliniká, ; grc, Ἑλληνική, Hellēnikḗ) is an independent branch of the Indo-European family of languages, native to Greece, Cyprus, southern Italy (Calabria and Salento), southern Albania, and other regions of the Balkans, the Black Sea coast, Asia Minor, and the Eastern Mediterranean. It has the longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system is the Greek alphabet, which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary. The alphabet arose from the Phoenician script and was in turn the basis of the Latin, Cyrillic, Armenian, Coptic, Gothic, and many other writing systems. The Greek language holds a very important place in the history of the Western world. Beginning with the epics of Homer, ancient Greek literature includes many works of lasting impo ...

Fern
A fern (Polypodiopsida or Polypodiophyta ) is a member of a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. The polypodiophytes include all living pteridophytes except the lycopods, and differ from mosses and other bryophytes by being vascular, i.e., having specialized tissues that conduct water and nutrients and in having life cycles in which the branched sporophyte is the dominant phase. Ferns have complex leaves called megaphylls, that are more complex than the microphylls of clubmosses. Most ferns are leptosporangiate ferns. They produce coiled fiddleheads that uncoil and expand into fronds. The group includes about 10,560 known extant species. Ferns are defined here in the broad sense, being all of the Polypodiopsida, comprising both the leptosporangiate (Polypodiidae) and eusporangiate ferns, the latter group including horsetails, whisk ferns, marattioid ferns, and ophioglossoid ferns. Ferns first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Citrus
''Citrus'' is a genus of flowering plant, flowering trees and shrubs in the rue family, Rutaceae. Plants in the genus produce citrus fruits, including important crops such as Orange (fruit), oranges, Lemon, lemons, grapefruits, pomelos, and lime (fruit), limes. The genus ''Citrus'' is native to South Asia, East Asia, Southeast Asia, Melanesia, and Australia (continent), Australia. Various citrus species have been used and domesticated by indigenous cultures in these areas since ancient times. From there its cultivation spread into Micronesia and Polynesia by the Austronesian expansion (c. 3000–1500 BCE); and to the Middle East and the Mediterranean (c. 1200 BCE) via the incense trade route, and onwards to Europe and the Americas. History Citrus plants are native to subtropical and tropical regions of Asia, Island Southeast Asia, Near Oceania, and northeastern Australia. Domestication of citrus species involved much hybridization and introgression, leaving much uncertainty ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

CITES Appendix I
CITES (shorter name for the Convention on International Trade in Endangered Species of Wild Fauna and Flora, also known as the Washington Convention) is a multilateral treaty to protect endangered plants and animals from the threats of international trade. It was drafted as a result of a resolution adopted in 1963 at a meeting of members of the International Union for Conservation of Nature (IUCN). The convention was opened for signature in 1973 and CITES entered into force on 1 July 1975. Its aim is to ensure that international trade (import/export) in specimens of animals and plants included under CITES, does not threaten the survival of the species in the wild. This is achieved via a system of permits and certificates. CITES affords varying degrees of protection to more than 38,000 species. , Secretary-General of CITES is Ivonne Higuero. Background CITES is one of the largest and oldest conservation and sustainable use agreements in existence. There are three working langu ...
