Gardenia Actinocarpa
''Gardenia actinocarpa'' is a rare and endangered plant in the madder family Rubiaceae that grows in a very restricted area within the Wet Tropics rainforest of north-east Queensland. Description This species grows as an evergreen understory plant, reaching up to in height but flowering and fruiting once it reaches around . It is a spindly arborescent shrub with a stem diameter of around at breast height. The leaves are opposite and chartaceous (papery) with wavy edges, glossy mid green above and paler below, and attached to the twigs with a petiole around long. They measure between long and wide, and are generally obovate in shape. They have a long attenuate (tapering) base and an extended "drip tip". Stipules are conical, up to long and resinous. Flowers are terminal, solitary, actinomorphic and 6-merous, borne on pedicels between long. The calyx tube is green, coriaceous, and has six external longitudinal ridges extending into the laterally compressed calyx l ...

Floral Symmetry
Floral symmetry describes whether, and how, a flower, in particular its perianth, can be divided into two or more identical or mirror-image parts. Uncommonly, flowers may have no axis of symmetry at all, typically because their parts are spirally arranged. Actinomorphic Most flowers are actinomorphic ("star shaped", "radial"), meaning they can be divided into 3 or more identical sectors which are related to each other by rotation about the center of the flower. Typically, each sector might contain one tepal or one petal and one sepal and so on. It may or may not be possible to divide the flower into symmetrical halves by the same number of longitudinal planes passing through the axis: Oleander is an example of a flower without such mirror planes. Actinomorphic flowers are also called radially symmetrical or regular flowers. Other examples of actinomorphic flowers are the lily (''Lilium'', Liliaceae) and the buttercup (''Ranunculus'', Ranunculaceae). Zygomorphic Zygomorp ...

Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koine. Dia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Botanical Name
A botanical name is a formal scientific name conforming to the '' International Code of Nomenclature for algae, fungi, and plants'' (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the ''International Code of Nomenclature for Cultivated Plants'' (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae ( Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia)." The purpose of a formal name is to have a single name that is accepted and used worldwide for a particular plant or plant group. For example, the botanical name ''Bellis perennis'' denotes a plant species which is native to most of the countries of Europe and the Middle East, where it has accumulated various names in many languages. Later, the plant was intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Queensland Herbarium
The Queensland Herbarium ( Index Herbariorum code: BRI) is situated at the Brisbane Botanic Gardens, Mount Coot-tha, in Brisbane, Queensland, Australia. It is part of Queensland's Department of Environment and Science. It is responsible for discovering, describing, monitoring, modelling, surveying, naming and classifying Queensland's plants, and is the focus for information and research on the state's plants and plant communities. Origins The history of the Herbarium as an institution starts in 1855 with the appointment of Walter Hill as Superintendent of the Brisbane Botanic Gardens, four years before Queensland separated from New South Wales as a colony. In 1859, with Separation, Hill was appointed Colonial Botanist as well as remaining Director of the Gardens, a position he was to hold until 1881. At the time the main function of colonial botanic gardens was usually to facilitate the introduction of suitable economic plants, although native plants would be collected as wel ...

Leonard Webb (academic)
Leonard James Webb (28 October 1920 – 25 November 2008) was a widely awarded Australian ecologist and ethnobotanist who was the author or joint-author of over 112 scientific papers throughout the course of his professional career. His pioneering work as Senior Principal Research Scientist alongside Geoff Tracey in the CSIRO Rainforest Ecology Research Unit in the 1950s led to the publication of the first systematic classification of Australian rainforest vegetation in the ''Journal of Ecology'' in 1959. In the early '80s, after decades of ongoing research, Webb and Tracey had accumulated a large corpus of scientific evidence which confirmed that Australian tropical rainforests had evolved from Gondwana over 100 million years ago and were not, as previously believed, relatively recent arrivals from South East Asia. This discovery served to consolidate the scientific basis for a number of major conservation campaigns across Queensland and paved the way for the subsequent succe ...

Geoff Tracey
John Geoffrey Tracey (1930 – 30 July 2004) was an Australian ecologist and botanist whose pioneering research work in partnership with Dr. Leonard Webb within the Rainforest Ecology Unit of the CSIRO in the 1950s led to the publication of the first systematic classification of Australian rainforest vegetation in the ''Journal of Ecology'' in 1959. By the early 80's, after decades of ongoing research, Tracey and Webb had accumulated a significant corpus of scientific evidence in support of the theory that Australian tropical rainforests had evolved in Gondwana over 100 million years ago and were not, as previously believed, relatively recent arrivals from South East Asia. This evidence, in combination with Tracey and Webb's 1975 publication of a collection of 15 vegetation maps entitled "Vegetation of the Humid Tropical Region of North Queensland", and Tracey's 1982 paper "The Vegetation of the Humid Tropical Region of North Queensland", helped to establish the scientif ...

Dioecy
Dioecy (; ; adj. dioecious , ) is a characteristic of a species, meaning that it has distinct individual organisms (unisexual) that produce male or female gametes, either directly (in animals) or indirectly (in seed plants). Dioecious reproduction is biparental reproduction. Dioecy has costs, since only about half the population directly produces offspring. It is one method for excluding self-fertilization and promoting allogamy (outcrossing), and thus tends to reduce the expression of recessive deleterious mutations present in a population. Plants have several other methods of preventing self-fertilization including, for example, dichogamy, herkogamy, and self-incompatibility. Dioecy is a dimorphic sexual system, alongside gynodioecy and androdioecy. In zoology In zoology, dioecious species may be opposed to hermaphroditic species, meaning that an individual is either male or female, in which case the synonym gonochory is more often used. Most animal species are dioecious (gon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petal
Petals are modified Leaf, leaves that surround the reproductive parts of flowers. They are often advertising coloration, brightly colored or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually accompanied by another set of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include Genus, genera such as ''Aloe'' and ''Tulipa''. Conversely, genera such as ''Rose, Rosa'' and ''Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly colored tepals. Sinc ...
