Leucospermum Tomentosum
''Leucospermum tomentosum'' is an evergreen, mostly spreading shrublet of approximately 75 cm (3 ft) high and up to 3 m (10 ft) in diameter, with alternately set, linear or narrowly spade-shaped, grey felty leaves, with one to three teeth near the tip. It has round, seated flower heads of 3–3½ cm (1.2–1.4 in) in diameter, occurring in groups of one to four, and consisting of deep yellow, very sweet scented flowers. It can survive the occasional wildfire because it regenerates from the underground rootstock. It is an Endemism, endemic species that is restricted to a narrow strip along the Atlantic coast of the Western Cape province of South Africa. The species flowers between June and November. It is called Saldanha pincushion in English. Description ''Leucodendron tomentosum'' is an evergreen shrublet of 0.4–1.0 m (1⅓–3⅓ ft) high and ½–3 m (1⅔–10 ft) in diameter, initially with upright and spreading branches, that later are weig ...

Carl Peter Thunberg
Carl Peter Thunberg, also known as Karl Peter von Thunberg, Carl Pehr Thunberg, or Carl Per Thunberg (11 November 1743 – 8 August 1828), was a Swedish naturalist and an "apostle" of Carl Linnaeus. After studying under Linnaeus at Uppsala University, he spent seven years travelling in southern Africa and Asia, collecting and describing many plants and animals new to European science, and observing local cultures. He has been called "the father of South African botany", "pioneer of Occidental Medicine in Japan", and the "Japanese Linnaeus". Early life Thunberg was born and grew up in Jönköping, Sweden. At the age of 18, he entered Uppsala University where he was taught by Carl Linnaeus, regarded as the "father of modern taxonomy". Thunberg graduated in 1767 after 6 years of studying. To deepen his knowledge in botany, medicine and natural history, he was encouraged by Linnaeus in 1770 to travel to Paris and Amsterdam. In Amsterdam and Leiden Thunberg met the Dutch bota ...

Perianth
The perianth (perigonium, perigon or perigone in monocots) is the non-reproductive part of the flower, and structure that forms an envelope surrounding the sexual organs, consisting of the calyx (sepals) and the corolla ( petals) or tepals when called a perigone. The term ''perianth'' is derived from Greek περί (, "around") and άνθος (, "flower"), while ''perigonium'' is derived from περί () and γόνος (, "seed, sex organs"). In the mosses and liverworts (Marchantiophyta), the perianth is the sterile tubelike tissue that surrounds the female reproductive structure (or developing sporophyte). Flowering plants In flowering plants, the perianth may be described as being either dichlamydeous/heterochlamydeous in which the calyx and corolla are clearly separate, or homochlamydeous, in which they are indistinguishable (and the sepals and petals are collectively referred to as tepals). When the perianth is in two whorls, it is described as biseriate. While t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joseph Knight (horticulturist)
Joseph Knight (7 October 1778 – 20 July 1855), gardener to George Hibbert, was one of the first people in England to successfully propagate Proteaceae. He is remembered as the nominal author of a publication that caused one of the biggest controversies of 19th-century English botany. Career Born in Brindle, Lancashire, he became head gardener to George Hibbert, who was an enthusiastic amateur botanist. Hibbert became caught up in the craze for cultivating Proteaceae, and as a result Knight became adept at their cultivation and propagation. He eventually set himself to write a book on their cultivation, which would be published in 1809 under the title ''On the cultivation of the plants belonging to the natural order of Proteeae''. Despite the title, this book contained only 13 pages related to cultivation techniques, but over 100 pages of taxonomic revision. Although not explicitly attributed, this 100 page revision is known to have been contributed by Richard Salisbury. In it, ...

Richard Anthony Salisbury
Richard Anthony Salisbury, FRS (born Richard Anthony Markham; 2 May 1761 – 23 March 1829) was a British botanist. While he carried out valuable work in horticultural and botanical sciences, several bitter disputes caused him to be ostracised by his contemporaries. Life Richard Anthony Markham was born in Leeds, England, as the only son of Richard Markham, a cloth merchant and Elizabeth Laycock. His family included two sisters, including his older sister Mary (b. 1755). One of his sisters became a nun. His mother, was the great grand-daughter of Jonathan Laycock of Shaw Hill. Laycock in turn married Mary Lyte (b. 1537), brother of Henry Lyte, the botanist and translator of the herbal of Dodoens. Of this, he wrote "so I inherit a taste for botany from very ancient blood". He studied at a school near Halifax and by the age of eight had established a passion for plants. He attended medical school at the University of Edinburgh in 1780, where he would have at least ...

Leucospermum
''Leucospermum'' is a genus of evergreen upright, sometimes creeping shrubs that is assigned to the Proteaceae, with currently forty-eight known species. Almost all species are easily recognised as ''Leucospermum'' because of the long protruding styles with a thickened pollen-presenter, which jointly give the flower head the appearance of a pincushion, its common name. Pincushions can be found in South Africa, Swaziland, Zimbabwe and Mozambique. The shrubs mostly have a single stem at their base, but some species sprout from an underground rootstock, from which the plant can regrow after fire has killed the above ground biomass. In a larger group of species, specimens are killed by fire, and their survival depends on the seeds. In all species, seeds are collected by ants, which take them to their underground nests to feed on their ant breads, a seed dispersal strategy known as myrmecochory. This ensures that the seeds do not burn, so new plants can grow from them. ''Leucosper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Section (biology)
In biology a section ( la, sectio) is a taxonomic rank that is applied differently in botany and zoology. In botany Within flora (plants), 'section' refers to a ''botanical'' rank below the genus, but above the species: * Domain > Kingdom > Division > Class > Order > Family > Tribe > Genus > Subgenus > Section > Subsection > Species In zoology Within fauna (animals), 'section' refers to a ''zoological'' rank below the order, but above the family: * Domain > Kingdom > Phylum > Class > Order > Section > Family > Tribe > Genus > Species In bacteriology The International Code of Nomenclature for Bacteria The International Code of Nomenclature of Prokaryotes (ICNP) formerly the International Code of Nomenclature of Bacteria (ICNB) or Bacteriological Code (BC) governs the scientific names for Bacteria and Archaea.P.

Diploid
Ploidy () is the number of complete sets of chromosomes in a cell, and hence the number of possible alleles for autosomal and pseudoautosomal genes. Sets of chromosomes refer to the number of maternal and paternal chromosome copies, respectively, in each homologous chromosome pair, which chromosomes naturally exist as. Somatic cells, tissues, and individual organisms can be described according to the number of sets of chromosomes present (the "ploidy level"): monoploid (1 set), diploid (2 sets), triploid (3 sets), tetraploid (4 sets), pentaploid (5 sets), hexaploid (6 sets), heptaploid or septaploid (7 sets), etc. The generic term polyploid is often used to describe cells with three or more chromosome sets. Virtually all sexually reproducing organisms are made up of somatic cells that are diploid or greater, but ploidy level may vary widely between different organisms, between different tissues within the same organism, and at different stages in an organism's life cycle. ...

Ovary (botany)
In the flowering plants, an ovary is a part of the female reproductive organ of the flower or gynoecium. Specifically, it is the part of the pistil which holds the ovule(s) and is located above or below or at the point of connection with the base of the petals and sepals. The pistil may be made up of one carpel or of several fused carpels (e.g. dicarpel or tricarpel), and therefore the ovary can contain part of one carpel or parts of several fused carpels. Above the ovary is the style and the stigma, which is where the pollen lands and germinates to grow down through the style to the ovary, and, for each individual pollen grain, to fertilize one individual ovule. Some wind pollinated flowers have much reduced and modified ovaries. Fruits A fruit is the mature, ripened ovary of a flower following double fertilization in an angiosperm. Because gymnosperms do not have an ovary but reproduce through double fertilization of unprotected ovules, they produce naked seeds that do ...
