Aeonium Leucoblepharum
''Aeonium leucoblepharum'' is a succulent flowering plant Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants th ... in the family '' Crassulaceae''. The pointed leaves have a strong central stripe, and they may develops pinkish colour on exposure to strong sunlight. There are variants with less pointed leaves but still with the central stripe. The flowers are yellow, 7- to 10-merous, with petals 6 – 8 x 1.8 – 2.5 mm. The species is native to mountains in Yemen and north-eastern Africa, from Ethiopia and Somalia to Kenya and Uganda. It is also known as ''Sempervivum leucoblepharum'' and ''Sempervivum chrysanthum''. References leucoblepharum {{Crassulaceae-stub ...

Philip Barker Webb
Philip Barker Webb (10 July 1793 – 31 August 1854) was an English botanist. Life Webb was born to a wealthy, aristocratic family; his father was the lord of the manors of Witley and Milford, Surrey, Milford, in Surrey, England. Webb was educated at Harrow School and Christ Church, Oxford. He collected plants in Italy, Spain, and Portugal, and was the first person to collect in the Tetuan Mountains of Morocco. En route to Brazil he made what was intended to be a brief visit to the Canary Islands, but he stayed for a considerable time, returning after his Brazil expedition. The results can be seen in the nine-volume ''Natural History of the Canary Islands, Histoire Naturelle des Iles Canaries'' (''Natural History of the Canary Islands''), which he co-authored with Sabin Berthelot. In company with Berthelot, who had lived on the islands for some time, Webb collected specimens on the islands between 1828 and 1830. The text of ''Histoire Naturelle des Iles Canaries'' took 20&nb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crassulaceae
The Crassulaceae (from Latin ''crassus'', thick), also known as the stonecrop family or the orpine family, are a diverse family of dicotyledon flowering plants characterized by succulent leaves and a unique form of photosynthesis, known as Crassulacean acid metabolism (CAM). Flowers generally have five floral parts. Crassulaceae are usually herbaceous but there are some subshrubs, and relatively few treelike or aquatic plants. Crassulaceae are a medium size monophyletic family in the core eudicots, among the order Saxifragales, whose diversity has made infrafamilial classification very difficult. The family includes approximately 1,400 species and 34–35 genera, depending on the circumscription of the genus ''Sedum'', and distributed over three subfamilies. Members of the Crassulaceae are found worldwide, but mostly in the Northern Hemisphere and southern Africa, typically in dry and/or cold areas where water may be scarce, although a few are aquatic. Crassulaceae are mainly pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
