Pimelea Cremnophila
''Pimelea cremnophila'', commonly known as gorge rice-flower, is a species of flowering plant in the family Thymelaeaceae and is endemic to a restricted area of New South Wales. It is an erect shrub with narrowly elliptic to narrowly egg-shaped leaves arranged in opposite pairs, and groups of up to four flowers that are sometimes male-only or female-only. Description ''Pimelea cremnophila'' is an erect shrub that typically grows to a height of up to and has reddish-brown stems, covered with bristly hairs when young. Its leaves are narrowly elliptic to narrowly egg-shaped, long and wide on a densely hairy petiole about long. The flowers are borne on the ends of branches or in leaf axils, singly or in groups of up to four on a peduncle about long. There are leaf like bracts long at the base of the flowers but that fall off as the flowers develop. Some flowers are functionally male, others functionally female and the remainder bisexual. Bisexual flowers have a floral tube ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sepal
A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 The term ''sepalum'' was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively the sepals are called the calyx (plural calyces), the outermost whorl of parts that form a flower. The word ''calyx'' was adopted from the Latin ,Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 not to be confused with 'cup, goblet'. ''Calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet', and the words have been used interchangeably in botanical Latin. After flowering, most plants have no more use for the calyx which withers or becomes vestigial. Some plants retain a thorny calyx, either dried or live, ...

Malvales Of Australia
The Malvales are an order of flowering plants. As circumscribed by APG II-system, the order includes about 6000 species within 9 families. The order is placed in the eurosids II, which are part of the eudicots. The plants are mostly shrubs and trees; most of its families have a cosmopolitan distribution in the tropics and subtropics, with limited expansion into temperate regions. An interesting distribution occurs in Madagascar, where three endemic families of Malvales (Sphaerosepalaceae, Sarcolaenaceae and Diegodendraceae) occur. Many species of Malvaceae ''sensu lato'' are known for their wood, with that of '' Ochroma'' (balsa) being known for its lightness, and that of ''Tilia'' (lime, linden, or basswood) as a popular wood for carving. Fruit of the cacao tree (''Theobroma cacao'') are used as an ingredient for chocolate. Kola nuts (genus ''Cola'') are notable for their high content of caffeine and, in past, were commonly used for preparing of various cola drinks. Other ...

Pimelea
''Pimelea'', commonly known as rice flowers, is a genus of plants belonging to the Family (biology), family Thymelaeaceae. There are about 150 species, including 110 in Australia and thirty six in New Zealand. Description Plants in the genus ''Pimelea'' are Herbaceous plant, herbs or small shrubs usually with leaves arranged in opposite pairs. The leaves are usually paler on the lower surface and the Petiole (botany), petiole is usually very short. The flowers are usually arranged in groups on the ends of the branches and have no petals but four petal-like sepals and two stamens. The Ovary (botany), ovary has a single ovule and the fruit is usually a Nut (fruit), nut containing a single seed. Taxonomy and naming The genus ''Pimelea'' was first formally described in 1788 by Joseph Gaertner from unpublished descriptions by Joseph Banks and Daniel Solander.

Biodiversity Conservation Act 2016 (NSW)
The ''Biodiversity Conservation Act 2016'' (''BC Act'') is a state-based act of parliament in New South Wales (NSW). Its long title is ''An Act relating to the conservation of biodiversity; and to repeal the Threatened Species Conservation Act 1995, the Nature Conservation Trust Act 2001 and the animal and plant provisions of the National Parks and Wildlife Act 1974''. It supersedes the '' Threatened Species Conservation Act 1995'', and commenced on 25 August 2017. The purpose of the Act was to effect biodiversity reform in New South Wales, in particular to provide better environmental outcomes and reduce burdensome regulations. The Act lists many more purposes under the rubric of "ecologically sustainable development" than the former Act, and specifically mentions "biodiversity conservation in the context of a changing climate". and since mid-2019, the BC Act is administered by the NSW Department of Planning, Industry and Environment.

Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus '' Homo'' and within this genus to the species '' Homo sapiens''. '' Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxley Wild Rivers National Park
The Oxley Wild Rivers National Park is a protected national park that is located in the Northern Tablelands region of New South Wales, Australia in the Port Macquarie-Hastings City Council and Walcha Shire councils. The park is situated north of Sydney and is named in memory of the Australian explorer John Oxley, who passed through the area in 1818 and is one of the largest national parks in New South Wales. The park is part of the Hastings-Macleay Group World Heritage Site Gondwana Rainforests of Australia inscribed in 1986 and added to the Australian National Heritage List in 2007. The Oxley Wild Rivers National Park (OWRNP) was World Heritage listed in recognition of the extensive dry rainforest that occurs within the park, and the associated rich biodiversity that includes several rare or threatened plants and animals. There are at least fourteen waterfalls in the park. History For thousands of years, the Northern Tablelands and these valleys were the tribal lan ...

Ian Telford
Ian or Iain is a name of Scottish Gaelic origin, derived from the Hebrew given name (Yohanan, ') and corresponding to the English name John. The spelling Ian is an Anglicization of the Scottish Gaelic forename ''Iain''. It is a popular name in Scotland, where it originated, as well as other English-speaking countries. The name has fallen out of the top 100 male baby names in the United Kingdom, having peaked in popularity as one of the top 10 names throughout the 1960s. In 1900, Ian was the 180th most popular male baby name in England and Wales. , the name has been in the top 100 in the United States every year since 1982, peaking at 65 in 2003. Other Gaelic forms of "John" include "Seonaidh" ("Johnny" from Lowland Scots), "Seon" (from English), "Seathan", and "Seán" and "Eoin" (from Irish).

Hypanthium
In angiosperms, a hypanthium or floral cup is a structure where basal portions of the calyx, the corolla, and the stamens form a cup-shaped tube. It is sometimes called a floral tube, a term that is also used for corolla tube and calyx tube. It often contains the nectaries of the plant. It is present in many plant families, although varies in structural dimensions and appearance. This differentiation between the hypanthium in particular species is useful for identification. Some geometric forms are obconic shapes as in toyon, whereas some are saucer-shaped as in ''Mitella caulescens''. Its presence is diagnostic of many families, including the Rosaceae, Grossulariaceae, and Fabaceae. In some cases, it can be so deep, with such a narrow top, that the flower can appear to have an inferior ovary - the ovary is below the other attached floral parts. The hypanthium is known by different common names in differing species. In the eucalypts, it is referred to as the ''gum nut' ...

Plant Reproductive Morphology
Plant reproductive morphology is the study of the physical form and structure (the morphology) of those parts of plants directly or indirectly concerned with sexual reproduction. Among all living organisms, flowers, which are the reproductive structures of angiosperms, are the most varied physically and show a correspondingly great diversity in methods of reproduction. Plants that are not flowering plants (green algae, mosses, liverworts, hornworts, ferns and gymnosperms such as conifers) also have complex interplays between morphological adaptation and environmental factors in their sexual reproduction. The breeding system, or how the sperm from one plant fertilizes the ovum of another, depends on the reproductive morphology, and is the single most important determinant of the genetic structure of nonclonal plant populations. Christian Konrad Sprengel (1793) studied the reproduction of flowering plants and for the first time it was understood that the pollination process involve ...

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] |
