Sedum Leibergii
''Sedum'' is a large genus of flowering plants in the family Crassulaceae, members of which are commonly known as stonecrops. The genus has been described as containing up to 600 species, subsequently reduced to 400–500. They are leaf succulents found primarily in the Northern Hemisphere, but extending into the southern hemisphere in Africa and South America. The plants vary from Annual plant, annual and creeping Herbaceous plant, herbs to shrubs. The plants have water-storing leaves. The flowers usually have five petals, seldom four or six. There are typically twice as many stamens as petals. Various species formerly classified as ''Sedum'' are now in the segregate genera ''Hylotelephium'' and ''Rhodiola''. Well-known European species of ''Sedum'' are ''Sedum acre'', ''Sedum album'', ''Sedum dasyphyllum'', ''Sedum reflexum'' (also known as ''Sedum rupestre'') and ''Sedum hispanicum''.

Sedum Acre
''Sedum acre'', commonly known as the goldmoss stonecrop, mossy stonecrop,Dickinson, T.; Metsger, D.; Bull, J.; & Dickinson, R. (2004) ROM Field Guide to Wildflowers of Ontario. Toronto:Royal Ontario Museum, p. 243. goldmoss sedum, biting stonecrop and wallpepper, is a perennial flowering plant in the family Crassulaceae. It is native to Europe, but also naturalised in North America, Japan and New Zealand. Description Biting stonecrop is a tufted evergreen perennial that forms mat-like stands some tall. For much of the year the stems are short, semi-prostrate and densely clad in leaves. At the flowering time in June and July, the stems lengthen and are erect, somewhat limp and often pinkish-brown with the leaves further apart. The leaves are alternate, fleshy and shortly cylindrical with a rounded tip. They are also sometimes tinged with red. The starry flowers form a three to six-flowered cyme. The calyx has five fleshy sepals fused at the base, the corolla consists of five re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Augustin Pyramus De Candolle
Augustin Pyramus (or Pyrame) de Candolle (, , ; 4 February 17789 September 1841) was a Swiss botanist. René Louiche Desfontaines launched de Candolle's botanical career by recommending him at a herbarium. Within a couple of years de Candolle had established a new genus, and he went on to document hundreds of plant families and create a new natural plant classification system. Although de Candolle's main focus was botany, he also contributed to related fields such as phytogeography, agronomy, paleontology, medical botany, and economic botany. De Candolle originated the idea of "Nature's war", which influenced Charles Darwin and the principle of natural selection. de Candolle recognized that multiple species may develop similar characteristics that did not appear in a common evolutionary ancestor; a phenomenon now known as convergent evolution. During his work with plants, de Candolle noticed that plant leaf movements follow a near-24-hour cycle in constant light, suggestin ...

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] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Thomas Thomson (botanist)
Thomas Thomson (4 December 1817 – 18 April 1878) was a British surgeon with the British East India Company before becoming a botanist. He was a friend of Joseph Dalton Hooker and helped write the first volume of ''Flora Indica''. He was born in Glasgow the son of Thomas Thomson, chemistry professor at Glasgow University. He qualified as an M.D. at Glasgow University in 1839, as was appointed Assistant Surgeon in the Bengal Army 21 December 1839. He served during the campaign in Afghanistan 1839-1842 being present at the capture of Ghazni in 1839 and was taken prisoner at Ghazni in March 1842 but was released 21 September 1842. He served in the Sutlej campaign, 1845–46, being present at Firuzshahr, and in the second Sikh war, 1848–49. During 1847–48, Thomson served on the Kashmir Boundary Commission under the leadership of Alexander Cunningham. ( Henry Strachey was the other commissioner.) Thomson explored the northern frontier of Kashmir, along the Karakoram Range. He ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hook
A hook is a tool consisting of a length of material, typically metal, that contains a portion that is curved or indented, such that it can be used to grab onto, connect, or otherwise attach itself onto another object. In a number of uses, one end of the hook is pointed, so that this end can pierce another material, which is then held by the curved or indented portion. Some kinds of hooks, particularly fish hooks, also have a barb, a backwards-pointed projection near the pointed end of the hook to ensure that once the hook is embedded in its target, it can not easily be removed. Variations * Bagging hook, a large sickle or reaping hook used for harvesting grain * Bondage hook, used in sexual bondage play * Cabin hook, a hooked bar that engages into an eye screw, used on doors * Cap hook, hat ornament of the 15th and 16th centuries * Cargo hook (helicopter), different types of hook systems for helicopters * Crochet hook, used for crocheting thread or yarn * Drapery hook, for ha ...

Sedella (plant)
''Sedella'' (formerly ''Parvisedum'') is a small genus of annual flowering plants in the family Crassulaceae. There are approximately 7 species, all native to California, United States, one with a distribution extending into Oregon. These are petite succulent plants growing a few centimeters tall and bearing tiny yellowish or brownish flowers. Mock stonecrop is a common name for these plants. Description These plants are diminutive annuals, they grow erect and are glabrous (without hairs). The leaves are early-deciduous, sessile, and shaped oblong-elliptic to ovoid. The tips of the leaves are rounded to obtuse. The inflorescence has 1 to 2 flowers in 0 to 3 branched cyme, sub-sessile. There are 5 sepals and 5 petals. The petals are pale to bright or green-yellow, with a midrib that is often more or less red.
