Goodeniaceae
Goodeniaceae is a family (biology), family of flowering plants in the Order (biology), order Asterales. It contains about 404 species in twelve genera. The family is distributed mostly in Australia, except for the genus ''Scaevola (plant), Scaevola'', which is pantropical. Its species are found across most of Australia, being especially common in arid and semi-arid climates. Morphology Species in Goodeniaceae are generally Herbaceous plant, herbaceous with Phyllotaxis, spiral leaves. Flowers have a single plane of symmetry (monosymmetric; ''Brunonia'' being the sole exception), and are either fan-like (e.g., ''Scaevola (plant), Scaevola'') or bilabiate (as in ''Dampiera''). Corolla (flower), Corolla lobes often have two thin marginal wings, which also occur in other families of Asterales such as the Menyanthaceae and Argophyllaceae. The style bears a pollen-cup, also known as an indusium, at the tip, a unique character for the family. The indusium has a function in secondary polle ...

Endemic
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bracts
In botany, a bract is a modified or specialized leaf, especially one associated with a reproductive structure such as a flower, inflorescence axis or cone scale. Bracts are usually different from foliage leaves. They may be smaller, larger, or of a different color, shape, or texture. Typically, they also look different from the parts of the flower, such as the petals or sepals. A plant having bracts is referred to as bracteate or bracteolate, while one that lacks them is referred to as ebracteate and ebracteolate, without bracts. Variants Some bracts are brightly-coloured and serve the function of attracting pollinators, either together with the perianth or instead of it. Examples of this type of bract include those of ''Euphorbia pulcherrima'' (poinsettia) and ''Bougainvillea'': both of these have large colourful bracts surrounding much smaller, less colourful flowers. In grasses, each floret (flower) is enclosed in a pair of papery bracts, called the lemma (lower bract) and pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corolla (botany)
The perianth (perigonium, perigon or perigone in monocots) is the non-reproductive part of the flower, and structure that forms an envelope surrounding the sexual organs, consisting of the calyx (sepals) and the corolla (petals) or tepals when called a perigone. The term ''perianth'' is derived from Greek περί (, "around") and άνθος (, "flower"), while ''perigonium'' is derived from περί () and γόνος (, "seed, sex organs"). In the mosses and liverworts (Marchantiophyta), the perianth is the sterile tubelike tissue that surrounds the female reproductive structure (or developing sporophyte). Flowering plants In flowering plants, the perianth may be described as being either dichlamydeous/heterochlamydeous in which the calyx and corolla are clearly separate, or homochlamydeous, in which they are indistinguishable (and the sepals and petals are collectively referred to as tepals). When the perianth is in two whorls, it is described as biseriate. While the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Papilionaceous Flower
Papilionaceous flowers (from Latin: ''papilion'', a butterfly) are flowers with the characteristic irregular and butterfly-like corolla found in many, though not all, plants of the species-rich Faboideae subfamily of legumes. Tournefort suggested that the term ''Flores papilionacei'' originated with Valerius Cordus, who applied it to the flowers of the bean. Structure Corolla The flowers have a bilateral symmetry with the corolla consisting of five petals. A single, large, upper petal is known as the banner (also vexillum or standard petal). The semi-cylindrical base of the banner embraces and compresses two equal and smaller lateral wings (or alae). The wings in turn enclose a pair of small keel petals, that are situated somewhat lower than the wings, but are interior to them. They have concave sides and correspond with the shape of the wings. The two keel petals are fused at their bases or stuck together to form a boat-shaped structure that encloses the essential flower organs ...

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] |
Learmonth, Western Australia
RAAF Base Learmonth, also known as Learmonth Airport , is a joint use Royal Australian Air Force base and civil airport. It is located near the town of Exmouth on the north-west coast of Western Australia. RAAF Base Learmonth is one of the RAAF's three bare bases. No RAAF units are currently based at Learmonth and it is maintained by a small caretaker staff during peacetime. The RAAF also operates the Learmonth Air Weapons Range which covers about and is located south-west of the airbase. History During World War II a little-known landing field was constructed on the western shore of Exmouth Gulf. It was code-named "Potshot" and maintained by No. 76 Operational Base Unit, in support of Operation Potshot. In the 1950s the landing field was further developed as a military base and named RAAF Learmonth in honour of Wing Commander Charles Learmonth DFC and Bar, who, while leading No. 14 Squadron, was killed in a flying accident off Rottnest Island, Western Australia on 6 Janua ...

Scaevola (plant)
''Scaevola'' is a genus of flowering plants in the ''Goodenia'' family, Goodeniaceae. It consists of more than 130 species, with the center of diversity being Australia and Polynesia. There are around 80 species in Australia, occurring throughout the continent, in a variety of habitats. Diversity is highest in the South West, where around 40 species are endemic. Common names for ''Scaevola'' species include scaevolas, fan-flowers, half-flowers, and naupaka, the plants' Hawaiian name. The flowers are shaped as if they have been cut in half. Consequently, the generic name means "left-handed" in Latin. Many Hawaiian legends have been told to explain the formation of the shape of the flowers. In one version a woman tears the flower in half after a quarrel with her lover. The gods, angered, turn all naupaka flowers into half flowers and the two lovers remained separated while the man is destined to search in vain for another whole flower. ''Scaevola'' is the only Goodeniaceae genus t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
