Leucospermum Fulgens
''Leucospermum fulgens'' is an evergreen, upright shrub of up to 3 m (10 ft) high, from the family Proteaceae. It has hairless and leathery inverted lance-shaped to oblong leaves tipped with mostly three teeth and globe- to egg-shaped flowerheads of 6–8 cm in diameter, that consist of pink to orange, later crimson flowers. From the center of the flowers emerge almost straight styles that jointly give the impression of a pincushion. It is called Potberg pincushion in English. New pink to orange flower heads occur between August and November, but older, crimson heads may persist until January. It is a critically endangered species, only known from one location in the Western Cape province of South Africa. Description ''Leucospermum fulgens'' is an upright and rounded shrub of up to 3 m (10 ft) high and 4 m (13 ft) across. It grows from a single main stem of up to 10 cm (4 in) thick, and has a smooth, grey bark. The flowering stems are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

Invasive Species
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin (''Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter (''Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of ...

Passerina (plant)
: ''Passerina'' is a genus in the plant family Thymelaeaceae. They are ericoid bushes growing largely in fynbos and other Southern African scrub habitats. Etymology The genus name ''Passerina'' derives from the Latin word ''passer'' " sparrow" - given the plants in reference to a perceived similarity in the shape of the fruit to a sparrow's beak - more evident in the Thymelaceous plant ''Thymelaea hirsuta'' (formerly placed in the genus ''Passerina''). Taxonomy Passerina L., Sp. Pl. 559 (1753); Wright in FC. 5, 2: 9 (1915); Thoday in Kew Bull. 1924: 146, 387 (1924). Chymococca Meissn., Wright 1.c. 14, is a genus of plants in the family Thymelaeaceae.Dyer, R. Allen, The Genera of Southern African Flowering Plants”. , 1975 Description Members of the genus ''Passerina'' are ericoid shrubs or shrublets, often with a tendency to having pendulous branches. Their leaves are markedly decussate. They are concave or closely involute, lined with woolly hairs, and cling to leafy s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Restionaceae
The Restionaceae, also called restiads and restios, are a family (biology), family of flowering plants native to the Southern Hemisphere; they vary from a few centimeters to 3 meters in height. Following the APG IV system, APG IV (2016): the family now includes the former families Anarthriaceae, Centrolepidaceae and Lyginiaceae, and as such includes 51 genera with 572 known species. Based on evidence from fossil pollens, the Restionaceae likely originated more than 65 million years ago during the Cretaceous, Late Cretaceous period, when the southern continents were still part of Gondwana.Bremer, K. (2002). "Gondwanan Evolution of the Grass Alliance of Families (Poales)." ''Evolution'', 56(7): 1374-1387 Description The family consists of tufted or rhizomatous, herbaceous plants belonging to a group of monocotyledons that includes several similar families, such as the Cyperaceae, sedges, Juncaceae, rushes, and Poaceae, grasses. They have green, photosynthetic stems and leaves that h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quaternary
The Quaternary ( ) is the current and most recent of the three periods of the Cenozoic Era in the geologic time scale of the International Commission on Stratigraphy (ICS). It follows the Neogene Period and spans from 2.58 million years ago to the present. The Quaternary Period is divided into two epochs: the Pleistocene (2.58 million years ago to 11.7 thousand years ago) and the Holocene (11.7 thousand years ago to today, although a third epoch, the Anthropocene, has been proposed but is not yet officially recognised by the ICS). The Quaternary Period is typically defined by the cyclic growth and decay of continental ice sheets related to the Milankovitch cycles and the associated climate and environmental changes that they caused. Research history In 1759 Giovanni Arduino proposed that the geological strata of northern Italy could be divided into four successive formations or "orders" ( it, quattro ordini). The term "quaternary" was introduced by Jules Desnoye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tertiary
Tertiary ( ) is a widely used but obsolete term for the geologic period from 66 million to 2.6 million years ago. The period began with the demise of the non-avian dinosaurs in the Cretaceous–Paleogene extinction event, at the start of the Cenozoic Era, and extended to the beginning of the Quaternary glaciation at the end of the Pliocene Epoch. The time span covered by the Tertiary has no exact equivalent in the current geologic time system, but it is essentially the merged Paleogene and Neogene periods, which are informally called the Early Tertiary and the Late Tertiary, respectively. The Tertiary established the Antarctic as an icy island continent. Historical use of the term The term Tertiary was first used by Giovanni Arduino during the mid-18th century. He classified geologic time into primitive (or primary), secondary, and tertiary periods based on observations of geology in Northern Italy. Later a fourth period, the Quaternary, was applied. In the early d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alexandria Formation
Alexandria ( or ; ar, ٱلْإِسْكَنْدَرِيَّةُ ; grc-gre, Αλεξάνδρεια, Alexándria) is the second largest city in Egypt, and the largest city on the Mediterranean coast. Founded in by Alexander the Great, Alexandria grew rapidly and became a major centre of Hellenic civilisation, eventually replacing Memphis, in present-day Greater Cairo, as Egypt's capital. During the Hellenistic period, it was home to the Lighthouse of Alexandria, which ranked among the Seven Wonders of the Ancient World, as well as the storied Library of Alexandria. Today, the library is reincarnated in the disc-shaped, ultramodern Bibliotheca Alexandrina. Its 15th-century seafront Qaitbay Citadel is now a museum. Called the "Bride of the Mediterranean" by locals, Alexandria is a popular tourist destination and an important industrial centre due to its natural gas and oil pipelines from Suez. The city extends about along the northern coast of Egypt, and is the largest city on th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
