Whorl (botany)
In botany, a whorl or verticil is an arrangement of leaves, sepals, petals, stamens, or carpels that radiate from a single point and surround or wrap around the stem or stalk. A leaf whorl consists of at least three elements; a pair of opposite leaves is not called a whorl. For leaves to grow in whorls is fairly rare except in plant species with very short internodes and some other genera (Galium, Nerium, Elodea etc.). Leaf whorls occur in some trees such as ''Brabejum stellatifolium'' and other species in the family Proteaceae (e.g., in the genus ''Banksia''). In plants such as these, crowded internodes within the leaf whorls alternate with long internodes between the whorls. The morphology of most flowers (called cyclic flowers) is based on four types of whorls: # The calyx: zero or more whorls of sepals at the base # The corolla: zero or more whorls of petals above the calyx # The androecium: zero or more whorls of stamens, each comprising a filament and an anther # The gyn ...

Myrtales Of Australia
The Myrtales are an order of flowering plants placed as a sister to the eurosids II clade as of the publishing of the ''Eucalyptus grandis'' genome in June 2014. The APG III system of classification for angiosperms still places it within the eurosids. This finding is corroborated by the placement of the Myrtales in the Malvid clade by the One Thousand Plant Transcriptomes Initiative. The following families are included as of APGIII: * Alzateaceae S. A. Graham * Combretaceae R. Br. ( leadwood family) * Crypteroniaceae A. DC. * Lythraceae J. St.-Hil. ( loosestrife and pomegranate family) * Melastomataceae Juss. (including Memecylaceae DC.) * Myrtaceae Juss. (myrtle family; including Heteropyxidaceae Engl. & Gilg, Psiloxylaceae Croizat) * Onagraceae Juss. (evening primrose and Fuchsia family) * Penaeaceae Sweet ex Guill. (including Oliniaceae Arn., Rhynchocalycaceae L. A. S. Johnson & B. G. Briggs) * Vochysiaceae A. St.-Hil. The Cronquist system gives essentially the same co ...

Plants Described In 2016
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 t ...

Flora Of Queensland
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kunzea
''Kunzea'' is a genus of plants in the family Myrtaceae and is endemic to Australasia. They are shrubs, sometimes small trees and usually have small, crowded, rather aromatic leaves. The flowers are similar to those of plants in the genus '' Leptospermum'' but differ in having stamens that are longer than the petals. Most kunzeas are endemic to Western Australia but a few occur in eastern Australia and a few are found in New Zealand. The taxonomy of the genus is not settled and is complicated by the existence of a number of hybrids. Description Plants in the genus ''Kunzea'' are shrubs or small trees, usually with their leaves arranged alternately along the branches. The flowers are arranged in clusters near the ends of the branches, which in some species, continue to grow after flowering. The flowers of most species lack a stalk but those that have one are usually solitary or in groups of two or three. In some species, the flowers are surrounded by enlarged bracts. There are ...

Nature Conservation Act 1992
The ''Nature Conservation Act 1992'' is an act of the Parliament of Queensland, Australia, that, together with subordinate legislation, provides for the legislative protection of Queensland's threatened biota. As originally published, it provided for biota to be declared ''presumed extinct'', ''endangered'', ''vulnerable'', ''rare'' or ''common''. In 2004 the act was amended to more closely align with the IUCN Red List categories: ''presumed extinct'' was changed to ''extinct in the wild'' and ''common'' was changed to ''least concern''. ''Near threatened'' was introduced as an eventual replacement for ''rare'', but the latter was to be phased out over time rather than immediately abandoned. The act is administered by the state's Environmental Protection Agency (EPA). There are provisions under the act which allow landholders to negotiate voluntary conservation agreements with the EPA. New regulations came into effect on 22 August 2020: Text may have been copied from this s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eungella National Park
Eungella National Park ( ; meaning "Land of the clouds") is a protected area in Queensland, Australia. It is on the Clarke Range at the end of the Pioneer Valley 80 km west of Mackay, and 858 km northwest of Brisbane. Eungella is noted for the national park which surrounds it. It is considered to be the longest continual stretch of sub-tropical rainforest in Australia. The original inhabitants are the Wirri people. The park is covered by dense rainforest and is known for its platypuses. Regional description Eungella National Park is located on an isolated massif about 80 km west of Mackay in North–central Queensland.Winter, J., and K. R. McDonald. 1986.

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 Nomenclature
Botanical nomenclature is the formal, scientific naming of plants. It is related to, but distinct from Alpha taxonomy, taxonomy. Plant taxonomy is concerned with grouping and classifying plants; botanical nomenclature then provides names for the results of this process. The starting point for modern botanical nomenclature is Carl Linnaeus, Linnaeus' ''Species Plantarum'' of 1753. Botanical nomenclature is governed by the ''International Code of Nomenclature for algae, fungi, and plants'' (''ICN''), which replaces the ''International Code of Botanical Nomenclature'' (''ICBN''). Fossil plants are also covered by the code of nomenclature. Within the limits set by that code there is another set of rules, the ''International Code of Nomenclature for Cultivated Plants, International Code of Nomenclature for Cultivated Plants (ICNCP)'' which applies to plant cultivars that have been deliberately altered or selected by humans (see cultigen). History and scope Botanical nomenclature has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adelaide Botanic Gardens
The Adelaide Botanic Garden is a public garden at the north-east corner of the Adelaide city centre, in the Adelaide Park Lands. It encompasses a fenced garden on North Terrace (between Lot Fourteen, the site of the old Royal Adelaide Hospital, and the National Wine Centre) and behind it the Botanic Park (adjacent to the Adelaide Zoo). Work was begun on the site in 1855, with its official opening to the public on 4 October 1857. The Adelaide Botanic Garden and adjacent State Herbarium of South Australia, together with the Wittunga Botanic Garden and Mount Lofty Botanic Garden, comprise the ''Botanic Gardens of South Australia'', administered by the Board of the Botanic Gardens and State Herbarium, a state government statutory authority. Early history From the first official survey carried out for the map of Adelaide, Colonel William Light intended for the planned city to have a "botanical garden". To this end, he designated a naturally occurring ait that had formed in the cour ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stamen
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains ''sporangium, microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna (plant), Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea'' ...
