Robert Brown (botanist, Born 1773)
Robert Brown (21 December 1773 – 10 June 1858) was a Scottish botanist and paleobotanist who made important contributions to botany largely through his pioneering use of the microscope. His contributions include one of the earliest detailed descriptions of the cell nucleus and cytoplasmic streaming; the observation of Brownian motion; early work on plant pollination and fertilisation, including being the first to recognise the fundamental difference between gymnosperms and angiosperms; and some of the earliest studies in palynology. He also made numerous contributions to plant taxonomy, notably erecting a number of plant families that are still accepted today; and numerous Australian plant genera and species, the fruit of his exploration of that continent with Matthew Flinders. Early life Robert Brown was born in Montrose on 21 December 1773, in a house that existed on the site where Montrose Library currently stands. He was the son of James Brown, a minister in the ...

Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually related to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant Dyes
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ability ...

Dry Season
The dry season is a yearly period of low rainfall, especially in the tropics. The weather in the tropics is dominated by the tropical rain belt, which moves from the northern to the southern tropics and back over the course of the year. The temperate counterpart to the tropical dry season is summer or winter. Rain belt The tropical rain belt lies in the southern hemisphere roughly from October to March; during that time the northern tropics have a dry season with sparser precipitation, and days are typically sunny throughout. From April to September, the rain belt lies in the northern hemisphere, and the southern tropics have their dry season. Under the Köppen climate classification, for tropical climates, a dry season month is defined as a month when average precipitation is below . The rain belt reaches roughly as far north as the Tropic of Cancer and as far south as the Tropic of Capricorn. Near these latitudes, there is one wet season and one dry season annually. At the ...

Vegetative Propagation
Vegetative reproduction (also known as vegetative propagation, vegetative multiplication or cloning) is any form of asexual reproduction occurring in plants in which a new plant grows from a fragment or cutting of the parent plant or specialized reproductive structures, which are sometimes called vegetative propagules. Many plants naturally reproduce this way, but it can also be induced artificially. Horticulturists have developed asexual propagation techniques that use vegetative propagules to replicate plants. Success rates and difficulty of propagation vary greatly. Monocotyledons typically lack a vascular cambium, making them more challenging to propagate. Background Plant propagation is the process of plant reproduction of a species or cultivar, and it can be sexual or asexual. It can happen through the use of vegetative parts of the plants, such as leaves, stems, and roots to produce new plants or through growth from specialized vegetative plant parts. While man ...

Australian Aboriginal Fibre Sculpture
The production of sculptural fibre objects has a long history within Aboriginal Australian culture. Historically, such objects had practical or ceremonial purposes, and some appeared in both contexts. The terms “art” and “craft” are difficult to apply in historical contexts, as they are not originally Aboriginal conceptual divisions. However, in a contemporary context, these objects are now generally regarded as contemporary art whenever they are presented as such. This categorisation is often applied to objects with historically practical or ceremonial applications, as well as a growing category of new fibre forms which have been innovated in the past decades and produced for a fine art market. The border between Aboriginal fibre sculpture and fibre craft is not clearly delineated, and some works may be regarded as either depending on the context of their display and use. Traditional Aboriginal fibre sculpture There are various examples of sculptural fibre works in pre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Livistona Humilis
''Livistona humilis'', the sand palm, is an Australian plant species of the family Arecaceae. It is a small, slender palm, growing to about 7 m tall and 5–8 cm dbh. It has 8 to 15 fan-shaped leaves, 30–50 cm long with petioles 40–70 cm long. It is endemic to the Top End of the Northern Territory in Australia. Genetic investigation suggests that its closest relation is ''Livistona inermis''. This palm is fire tolerant and usually grows in environments where it is exposed to frequent fires. ''Livistona humilis'' is dioecious and sexually dimorphic. The flower stalks on the female plant are erect and up to 230 cm long, while the male plant's flower stalks are up to 180 cm long and curved. The flowers are small and yellow, 2 mm to 4 mm across. Fruit is shiny purple black, ellipsoid, pyriform, or obovoid, 11–19 mm long and 8–10 mm in diameter. Taxonomy The first description of the species was by Robert Brown in his ''Pr ...

Pandanus Spiralis
''Pandanus spiralis'' is native to northern Australia. It is commonly called common screwpine, iidool, pandanus palm, screw pine, screw palm or spring pandanus. It is neither a true palm, nor a pine. Distribution ''Pandanus spiralis'' occurs in Queensland, Northern NSW, the Northern Territory and the extreme north of Western Australia. The plant is most commonly found growing along watercourses or coastal fringes and dune systems. Description ''Pandanus spiralis'' is a shrub or small tree up to 10 metres in height. It has long, spiny leaves organised in a spiral arrangement. The plant bears a large, pineapple-like cluster of fruit that turn orange-red when ripe. Wildlife including birds take advantage of the spiny leaves by living in the tree for protection. They also favor its fruit. Uses The leaves of ''P. spiralis'' can be used to weave neckbands and armbands. The fibre of the leaves can be used as string for dillybags. Other uses include baskets, mats, and shel ...

Lateritic Soils
Laterite is both a soil and a rock type rich in iron and aluminium and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content. They develop by intensive and prolonged weathering of the underlying parent rock, usually when there are conditions of high temperatures and heavy rainfall with alternate wet and dry periods. Tropical weathering (''laterization'') is a prolonged process of chemical weathering which produces a wide variety in the thickness, grade, chemistry and ore mineralogy of the resulting soils. The majority of the land area containing laterites is between the tropics of Cancer and Capricorn. Laterite has commonly been referred to as a soil type as well as being a rock type. This and further variation in the modes of conceptualizing about laterite (e.g. also as a complete weathering profile or theory about weathering) has led to calls for the term to be abandoned alto ...

Australasian Virtual Herbarium
The ''Australasian Virtual Herbarium'' (AVH) is an online resource that allows access to plant specimen data held by various Australian and New Zealand herbaria. It is part of the Atlas of Living Australia (ALA), and was formed by the amalgamation of ''Australia's Virtual Herbarium'' and ''NZ Virtual Herbarium''. As of 12 August 2014, more than five million specimens of the 8 million and upwards specimens available from participating institutions have been databased. Uses This resource is used by academics, students, and anyone interested in research in botany in Australia or New Zealand, since each record tells all that is known about the specimen: where and when it was collected; by whom; its current identification together with the botanist who identified it; and information on habitat and associated species. ALA post processes the original herbarium data, giving further fields with respect to taxonomy and quality of the data. When interrogating individual specimen record ...
