Annonaceae
The Annonaceae are a family of flowering plants consisting of trees, shrubs, or rarely lianas commonly known as the custard apple family or soursop family. With 108 accepted genera and about 2400 known species, it is the largest family in the Magnoliales. Several genera produce edible fruit, most notably ''Annona'', ''Anonidium'', ''Asimina'', '' Rollinia'', and '' Uvaria''. Its type genus is ''Annona''. The family is concentrated in the tropics, with few species found in temperate regions. About 900 species are Neotropical, 450 are Afrotropical, and the remaining are Indomalayan. Description The species are mostly tropical, some are mid-latitude, deciduous or evergreen trees and shrubs, with some lianas, with aromatic bark, leaves, and flowers. ; Stems, stalks and leaves: Bark is fibrous and aromatic. Pith septate (fine tangential bands divided by partitions) to diaphragmed (divided by thin partitions with openings in them). Branching distichous (arranged in two rows/on one ...

Ovule
In seed plants, the ovule is the structure that gives rise to and contains the female reproductive cells. It consists of three parts: the '' integument'', forming its outer layer, the ''nucellus'' (or remnant of the megasporangium), and the female gametophyte (formed from a haploid megaspore) in its center. The female gametophyte — specifically termed a ''megagametophyte''— is also called the ''embryo sac'' in angiosperms. The megagametophyte produces an egg cell for the purpose of fertilization. The ovule is a small structure present in the ovary. It is attached to the placenta by a stalk called a funicle. The funicle provides nourishment to the ovule. Location within the plant In flowering plants, the ovule is located inside the portion of the flower called the gynoecium. The ovary of the gynoecium produces one or more ovules and ultimately becomes the fruit wall. Ovules are attached to the placenta in the ovary through a stalk-like structure known as a ''funiculus'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian Plant Name Index
The Australian Plant Name Index (APNI) is an online database of all published names of Australian vascular plants. It covers all names, whether current names, synonyms or invalid names. It includes bibliographic and typification details, information from the Australian Plant Census including distribution by state, links to other resources such as specimen collection maps and plant photographs, and the facility for notes and comments on other aspects. History Originally the brainchild of Nancy Tyson Burbidge, it began as a four-volume printed work consisting of 3,055 pages, and containing over 60,000 plant names. Compiled by Arthur Chapman, it was part of the Australian Biological Resources Study (ABRS). In 1991 it was made available as an online database, and handed over to the Australian National Botanic Gardens. Two years later, responsibility for its maintenance was given to the newly formed Centre for Plant Biodiversity Research. Scope Recognised by Australian herbaria as t ...

Elemicin
Elemicin is a phenylpropene, a natural organic compound, and is a constituent of several plant species' essential oils. Natural occurrence Elemicin is a constituent of the oleoresin and the essential oil of '' Canarium luzonicum'' (also referred to as elemi). Elemicin is named after this tree. One study found it to compose 2.4% of the fresh essential oil. Elemicin is also present in the oils of the spices nutmeg and mace, with it composing 2.4% and 10.5% of those oils respectively. Structurally, elemicin is similar to myristicin, differing only by myristicin's methyl group that joins the two oxygen atoms that make up its dioxymethy moiety, with both constituents being found in nutmeg and mace. Isolation Elemicin was first isolated from elemi oil using vacuum distillation. Specifically, the substance was collected between 162-165 °C at a reduced pressure of 10 torr. Preparation Elemicin has been synthesized from syringol and allyl bromide using Williamson ethe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Least-concern Species
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the "Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15636) in the IUCN database still use the code "LR/lc", which indicates they have not been re-evalu ...

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] |
Port Douglas
Port Douglas is a coastal town and locality in the Shire of Douglas, Queensland, Australia, approximately 60 km north of Cairns. In the , Port Douglas had a population of 3,504 people. The town's population can often double, however, with the influx of tourists during the peak tourism season from May to September. The town is named in honour of a former Premier of Queensland, John Douglas. Port Douglas developed quickly based on the mining industry. Other parts of the area were established with timber cutting occurring in the area surrounding the Daintree River and with settlement starting to occur on lots around the Mossman River by 1880. Previous names for the town included Terrigal, Island Point, Port Owen and Salisbury. The town is situated adjacent to two World Heritage areas, the Great Barrier Reef and the Daintree Rainforest.

Mount Bellenden Ker
Mount Bellenden Ker is the second-highest mountain in Queensland, Australia, with a height of . It is named after the botanist John Bellenden Ker Gawler. Located south of Cairns near Babinda, it is adjacent to Mount Bartle Frere, the state's highest peak, part of the Bellenden Ker Range which is also known as the Wooroonooran Range. The two mountains dominate the Josephine Falls section of the Wooroonooran National Park. Both peaks are made of resistant granite and are remnants of an escarpment that has been eroded by the Russell and Mulgrave Rivers. Several television transmitter towers have been built on the mountain. The only access to the television transmitter site and the mountain top weather station is by a privately owned cable car. History In 1873, Walter Hill, Queensland's first Colonial botanist, undertook an expedition to northern Queensland to collect native plants and included a trip to Mount Bellenden Ker.
