Anigozanthus
''Anigozanthos'' is a genus of Southwest Australian plants of the bloodwort family Haemodoraceae. The 11 species and their subspecies are commonly known as kangaroo paw or catspaw, depending on their size, and the shape and color of their flowers. A further species, previously identified as ''Anigozanthos fuliginosus'' (black kangaroo paw), was separated to a monotypic genus as ''Macropidia fuliginosa''. The species are recognised by their unusual flowers, numerous hybrids and cultivars have been developed for cultivation and floristry in recent years; kangaroo paws are much in demand as house plants and as cut flowers. The red-and-green kangaroo paw is the floral emblem of Western Australia. Taxonomy The genus was first named by Jacques Labillardière, a French botanist, in his work, ''Relation du Voyage à la Recherche de la Pérouse'', issued in 1800; he collected and described the type species, ''Anigozanthos rufus'', during the d'Entrecasteaux expedition's visit to Sout ...

Macropidia Fuliginosa
''Macropidia fuliginosa'', the sole species of genus ''Macropidia'', is a perennial rhizomatous flowering plant. A relation of the kangaroo paws, '' Anigozanthus'', which are also endemic to Southwest Australia, it is referred to as the black kangaroo paw. Bearing unusual black and green flowers, it occurs on a coastal plain from Perth to Geraldton. Taxonomy A species of the Haemodoraceae family, once allied to the kangaroo paws '' Anigozanthus'', but recognised as a separate and monotypic sister genus named ''Macropidia''. It was first described by James Drummond in a letter intended for publication in 1843, and named as "''Anigozanthus Molloyiae''". Drummond wrote of this species as a flower of mourning, and provided the epithet in reference to the recently deceased Georgiana Molloy, an early botanical collector of the region. The first published description by W. J. Hooker in the ''Botanical Magazine'' provided the name ''Anigozanthos fuliginosa'' in 1847, but its later sep ...

Anigozanthos Onycis
''Anigozanthos onycis'', the branched catspaw, is a rarely seen plant found in Southwest Australia. Taxonomy ''Anigozanthos onycis'' was first described by Alex George in 1974. George assigned the epithet ''onycis'' for the clawed appearance of the flower when opened, derived from the Greek ''onyx'' (a talon or claw). The unknown species was brought to the attention of the author in 1962, at a flower show in Kalgoorlie (500 km beyond its known range), but the source of this specimen was not determined. A collection made by Honor Venning was presented to the Western Australian Herbarium in 1969, and another made by Bob Dixon, obtained from a private property south of the Stirling Range in 1972, was used by George for its formal description. The common name branched catspaw distinguishes the flowering scape of ''A. onycis'' from other species known as catspaws: ''A humilis'', ''A. preissii'' and ''A. kalbarriensis'', smaller species of ''Anigozanthus''. Catspaw is presumed to h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anigozanthos Humilis
''Anigozanthos humilis'' is a species of ''Anigozanthos'' in the family Haemodoraceae. This flowering perennial plant is endemic to Southwest Australia and widespread in its open forests. Common names include catspaw and common catspaw. Taxonomy The species was first described by John Lindley in the 1840 work '' A sketch of the vegetation of the Swan River Colony''. Three subspecies have also been described and recognised. The genus name ''Anigozanthos'' possibly combines Ancient Greek words "anisos", meaning unequal, and "anthos", meaning flower (in reference to the shape of the flowers). The specific epithet, ''humilis'', means "low-growing". The common name catspaw was initially applied this species, then for several other species of ''Anigozanthos'', this is assumed to have been coined to contrast these with larger flowers and scapes of 'kangaroo paws'. The widely occurring ''A. humilis'' subsp. ''humilis'' is referred to as the common catspaw. Description The species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anigozanthos Flavidus
''Anigozanthos flavidus'' is a species of plant found in Southwest Australia. It is member of the Haemodoraceae family. It is commonly known as the tall, yellow, or evergreen, kangaroo paw. The specific epithet, ''flavidus'', refers to the yellow flowers of this plant. A member of the genus '' Anigozanthos'' (kangaroo- and cats-paws) that has an evergreen clump of strap-like leaves, up to 1 metre long and 0.2 m wide, growing from an underground rhizome around 0.5 m in diameter. The rhizome allows the species to regenerate after drought or fire. Each plant may produce over 350 flowers, on up to 10 long stems, these appear during the summer of the region. Pollen is distributed by birds as they plunge into the flowers to reach the nectaries. Flowers are frequently yellow and green, but may present in shades of red, pink, orange, or brown. It is found along roadsides, along creeks, and in forests and swamps, and other unshaded winterwet habitat. The species occurs in a range from ...

Relation Du Voyage à La Recherche De La Pérouse
''Relation du Voyage à la Recherche de la Pérouse'' is an 1800 book that gives an account of the 1791-1793 d'Entrecasteaux expedition to Australasia. The title refers to the search for La Pérouse, who disappeared in the region in 1788, a popular, though unsuccessful, object of the mission. Many of the discoveries made by the scientists attached to the expedition were published in the two volumes. The author, Jacques Labillardière, was a French botanist on the voyage, engaged to collect and describe the flora of the continent. The work includes some of the earliest descriptions of Australian flora and fauna, and an account of the indigenous peoples of Tasmania. The work also contains the second ever description of an Australian spider, the species ''Trichonephila edulis''. Labillardière also describes seeing a dog-sized animal, and discovering the remains of a carnivorous animal, what is considered to be the first European report of a thylacine.

Silica
Silicon dioxide, also known as silica, is an oxide of silicon with the chemical formula , most commonly found in nature as quartz and in various living organisms. In many parts of the world, silica is the major constituent of sand. Silica is one of the most complex and most abundant families of materials, existing as a compound of several minerals and as a synthetic product. Notable examples include fused quartz, fumed silica, silica gel, opal and aerogels. It is used in structural materials, microelectronics (as an electrical insulator), and as components in the food and pharmaceutical industries. Structure In the majority of silicates, the silicon atom shows tetrahedral coordination, with four oxygen atoms surrounding a central Si atomsee 3-D Unit Cell. Thus, SiO2 forms 3-dimensional network solids in which each silicon atom is covalently bonded in a tetrahedral manner to 4 oxygen atoms. In contrast, CO2 is a linear molecule. The starkly different structures of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tuber
Tubers are a type of enlarged structure used as storage organs for nutrients in some plants. They are used for the plant's perennation (survival of the winter or dry months), to provide energy and nutrients for regrowth during the next growing season, and as a means of asexual reproduction. ''Stem tubers'' form thickened rhizomes (underground stems) or stolons (horizontal connections between organisms); well known species with stem tubers include the potato and yam. Some writers also treat modified lateral roots (''root tubers'') under the definition; these are found in sweet potatoes, cassava, and dahlias. Terminology The term originates from the Latin , meaning "lump, bump, swelling". Some writers define the term "tuber" to mean only structures derived from stems; others use the term for structures derived from stems or roots., p. 124 Stem tubers A stem tuber forms from thickened rhizomes or stolons. The top sides of the tuber produce shoots that grow into typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flower
A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Angiospermae). The biological function of a flower is to facilitate reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) resulting from cross-pollination or allow selfing (fusion of sperm and egg from the same flower) when self-pollination occurs. There are two types of pollination: self-pollination and cross-pollination. Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is when pollen is transferred from the anther of one flower to the stigma of another flower on a different individual of the same species. Self-pollination happens in flowers where the stamen and carpel mature at the same time, and are posi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
