Scaevola Glabrata
''Scaevola glabrata'' is a species of flowering plant in the family Goodeniaceae. It is a small, spreading shrub with fan-shaped blue flowers and elliptic to egg-shaped leaves. Description ''Scaevola glabrata'' is a spreading under-storey shrub to tall with upright needle-shaped stems that are glabrous or with occasional scattered hairs. The leaves are sessile or with a very short petiole, occasionally almost stem-clasping, egg-shaped, toothed, long and wide. The flowers are borne on spikes up to long, bracts elliptic-oval shaped and up to long. The blue corolla is long, hairy on the outside, bearded inside and the wings up to wide. Flowering occurs February to September and the fruit is cylinder-shaped, long, wrinkled and covered in soft hairs. Taxonomy and naming ''Scaevola glabrata'' was first formally described in 1986 by Roger Charles Carolin and the description was published in ''Flora of South Australia''. The specific epithet (''glabrata'') means glabrous. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Goodeniaceae
Goodeniaceae is a family of flowering plants in the order Asterales. It contains about 404 species in twelve genera. The family is distributed mostly in Australia, except for the genus '' 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 with spiral leaves. Flowers have a single plane of symmetry (monosymmetric; '' Brunonia'' being the sole exception), and are either fan-like (e.g., '' Scaevola'') or bilabiate (as in '' Dampiera''). 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 pollen presentation, a phenomenon also occurring in the related families Asteraceae and Campanulaceae. The ovary is ...

Glabrous (botany)
Glabrousness (from the Latin '' glaber'' meaning "bald", "hairless", "shaved", "smooth") is the technical term for a lack of hair, down, setae, trichomes or other such covering. A glabrous surface may be a natural characteristic of all or part of a plant or animal, or be due to loss because of a physical condition, such as alopecia universalis in humans, which causes hair to fall out or not regrow. In botany Glabrousness or otherwise, of leaves, stems, and fruit is a feature commonly mentioned in plant keys; in botany and mycology, a ''glabrous'' morphological feature is one that is smooth and may be glossy. It has no bristles or hair-like structures such as trichomes. In anything like the zoological sense, no plants or fungi have hair or wool, although some structures may resemble such materials. The term "glabrous" strictly applies only to features that lack trichomes at all times. When an organ bears trichomes at first, but loses them with age, the term used is ''glabrescen ...

Sessile (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 Substrate may refer to: Physical layers *Substrate (biology), the natural environment in which an organism lives, or the surface or medium on which ...

Petiole (botany)
In botany, the petiole () is the stalk that attaches the leaf blade to the stem, and is able to twist the leaf to face the sun. This gives a characteristic foliage arrangement to the plant. Outgrowths appearing on each side of the petiole in some species are called stipules. Leaves with a petiole are said to be petiolate, while leaves lacking a petiole are called sessile or apetiolate. Description The petiole is a stalk that attaches a leaf to the plant stem. In petiolate leaves, the leaf stalk may be long, as in the leaves of celery and rhubarb, or short. When completely absent, the blade attaches directly to the stem and is said to be sessile. Subpetiolate leaves have an extremely short petiole, and may appear sessile. The broomrape family Orobanchaceae is an example of a family in which the leaves are always sessile. In some other plant groups, such as the speedwell genus '' Veronica'', petiolate and sessile leaves may occur in different species. In the grasses ( Poacea ...

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 brac ... [...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 ca ... [...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 organ ...

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 w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arnhem Land
Arnhem Land is a historical region of the Northern Territory of Australia, with the term still in use. It is located in the north-eastern corner of the territory and is around from the territory capital, Darwin. In 1623, Dutch East India Company captain Willem Joosten van Colster (or Coolsteerdt) sailed into the Gulf of Carpentaria and Cape Arnhem is named after his ship, the ''Arnhem'', which itself was named after the city of Arnhem in the Netherlands. The area covers about and has an estimated population of 16,000, of whom 12,000 are Aboriginal and Torres Strait Islander people. Two regions are often distinguished as East Arnhem (Land) and West Arnhem (Land), and North-east Arnhem Land is known to the local Yolŋu people as Miwatj. The region's service hub is Nhulunbuy, east of Darwin, set up in the early 1970s as a mining town for bauxite. Other major population centres are Yirrkala (just outside Nhulunbuy), Gunbalanya (formerly Oenpelli), Ramingining, and Maningri ...

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 g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of South Australia
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is ''funga''. 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 Thurman ...
