Scaevola Densifolia
''Scaevola densifolia'' is a species of flowering plant in the family Goodeniaceae. It is a small, spreading shrub with fan-shaped cream or white flowers and is endemic to Western Australia. Description ''Scaevola densifolia'' is a small, prostrate, understorey perennial herb or shrub with hairy stems up to long. The leaves are sessile, oblong shaped, wider at the apex, sometimes in clusters, margins entire or a tooth on either side, long and wide. The flowers are borne in racemes at the end of branches, bracts leaf like. The corolla cream or white, long with thick more or less flattened hairs on the outside, bearded on the inside and the wings up to wide. Flowering occurs mostly from October to December and the fruit is cylinder shaped, long and covered with soft hairs. Taxonomy and naming ''Scaevola densifolia'' was first formally described in 1990 by Roger Charles Carolin and the description was published in '' Telopea''. The specific epithet (''densifolia'') mea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
Sessility (botany)
In botany, sessility (meaning "sitting", used in the sense of "resting on the surface") is a characteristic of plant parts (such as flowers and leaves) that have no stalk. Plant parts can also be described as subsessile, that is, not completely sessile. A sessile flower is one that lacks a pedicel (flower stalk). A flower that is not sessile is pedicellate. For example, the genus ''Trillium'' is partitioned into two subgenera, the sessile-flowered trilliums (''Trillium'' subg. ''Sessilium'') and the pedicellate-flowered trilliums. Sessile leaves lack petioles (leaf stalks). A leaf that is not sessile is petiolate. For example, the leaves of most monocotyledons lack petioles. The term sessility is also used in mycology to describe a fungal fruit body that is attached to or seated directly on the surface of the substrate, lacking a supporting stipe or pedicel Pedicle or pedicel may refer to: Human anatomy *Pedicle of vertebral arch, the segment between the transvers ...

Racemes
A raceme ( or ) or racemoid is an unbranched, indeterminate type of inflorescence bearing flowers having short floral stalks along the shoots that bear the flowers. The oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. Examples of racemes occur on mustard (genus ''Brassica'') and radish (genus ''Raphanus'') plants. Definition A ''raceme'' or ''racemoid'' is an unbranched, indeterminate type of inflorescence bearing pedicellate flowers (flowers having short floral stalks called ''pedicels'') along its axis. In botany, an ''axis'' means a shoot, in this case one bearing the flowers. In indeterminate inflorescence-like racemes, the oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. A plant that flowers on a showy raceme may have this reflected in its scientific name, e.g. the species ''Cimicifuga racemosa''. A compou ...

Bract
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 p ... [...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] |
Oldfield River
The Oldfield River is an ephemeral river in the Goldfields-Esperance region of Western Australia that rises inland from the South Coast at the edge of the Yilgarn plateau. The river starts at above sea level then flows in a south easterly direction crossing the South Coast Highway near Munglinup. The river gently undulates through sandstone forming gentle valleys with many granite outcrops, the river then carves deeper valleys through the siltstone before entering the coastal plain. The river is then joined by its tributary, the Munglinup River, before flowing into the Oldfield estuary which discharges into the Southern Ocean. The only other tributary of the Oldfield River is Coujinup Creek. The river is regarded as saline with high nutrient levels, moderate sedimentation, moderate fringing vegetation and has a low flood risk. Named as Oldfield river by the settler Michael Simon Dempster in a letter written in 1866, the river is thought to have been named after Augustus F ...

Fitzgerald River
The Fitzgerald River is a river in the Great Southern region of Western Australia. Surveyor General John Septimus Roe named the river during expeditions in the area in 1848 after the governor of Western Australia of the day, Charles Fitzgerald. The river rises near the Lake Magenta Nature Reserve about 300 m above sea level then flows in a southerly direction through farmland until it reaches the Fitzgerald River National Park. The headwaters are in a salt lake area where much of the land has been cleared for agricultural purposes; it is estimated that 40% of the catchment has been cleared. Once the river enters the national park it is flowing through unspoilt bush and has cut magnificent gorges into the plateau of spongolite. Some of the tributaries of the river include Sussetta River, Jacup Creek, Tertup Creek, Tooartup Creek and Martin Creek. The river discharges into Fitzgerald Inlet which covers a total area of , the central basin and barriers have an area of a ...
