Sedum Rubrotinctum 7
''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 and creeping 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'', and '' Sedum hispanicum''. Description ''Sedum'' is a genus that includes annual, biennial, and perennial herbs. They are characterised by succulent leaves and stems. The extent of morphological di ...

Sedum Acre
''Sedum acre'', commonly known as the goldmoss stonecrop, mossy stonecrop, goldmoss sedum, biting stonecrop, and wallpepper, is a perennial flowering plant in the family Crassulaceae. It is native to Europe, northern and western Asia and North Africa, but is also naturalised in North America, southern South America, Japan, and New Zealand. Description The 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 regular bright yellow petals, there are ten stamens, a separate g ...

Augustin Pyramus De Candolle
Augustin Pyramus (or Pyrame) de Candolle (, , ; 4 February 17789 September 1841) was a Swiss people, Swiss botany, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (). The term angiosperm is derived from the Ancient Greek, Greek words (; 'container, vessel') and (; 'seed'), meaning that the seeds are enclosed within a fruit. The group was formerly called Magnoliophyta. Angiosperms are by far the most diverse group of Embryophyte, land plants with 64 Order (biology), orders, 416 Family (biology), families, approximately 13,000 known Genus, genera and 300,000 known species. They include all forbs (flowering plants without a woody Plant stem, stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. Angiosperms are distinguished from the other major seed plant clade, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. 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 of an ancestral taxon are grouped together (i.e. Phylogeneti ...

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''. With Hooker he distributed the exsiccata-like series ''Herbarium Indiae orientalis''. 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 commissione ...

Hook
A hook is a tool consisting of a length of material, typically metal, that contains a portion that is curved/bent back or has a deeply grooved indentation, which serves to grab, latch or in any way attach itself onto another object. The hook's design allows traction forces to be relayed through the curved/indented portion to and from the proximal end of the hook, which is either a straight shaft (known as the hook's ''shank'') or a ring (sometimes called the hook's "''eye''") for attachment to a thread (yarn), thread, rope or chain, providing a reversible attachment between two objects. In many cases, the distal end of the hook is sharply pointed to enable penetration into the target material, providing a firmer anchorage. Some hooks, particularly fish hooks, also have a ''barb'', a backwards-pointed projection near the pointed end that functions as a secondary "mini-hook" to catch and trap surrounding material, ensuring that the hook point cannot be easily pulled back out once e ...

''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.
