Pimelea Ciliolaris
''Pimelea ciliolaris'' is a species of flowering plant in the family Thymelaeaceae and is endemic to a restricted area of New South Wales. It is a stunted shrub with narrowly elliptic leaves and heads of densely hairy, cream-coloured to pale yellow flowers. Description ''Pimelea ciliolaris'' is a stunted shrub that typically grows to a height of up to and has hairy stems. Its leaves are narrowly elliptic or linear, long and wide with a few hairs on the edge when young. The flowers are borne in compact heads on a peduncle long, surrounded by 9 to 15 involucral bracts long and wide tinged with purple. The sepals are about long, the floral tube about long and the stamens usually shorter than the sepals. Flowering occurs from October to December. Taxonomy This pimelea was first formally described in 1983 by S. Threlfall who gave it the name ''Pimelea octophylla'' subsp. ''ciliolaris'' in the journal ''Brunonia'' from specimens collected in the Warrumbungle Ranges in 1899. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian National Botanic Gardens
The Australian National Botanic Gardens (ANBG) is a heritage-listed botanical garden located in , Canberra, in the Australian Capital Territory, Australia. Established in 1949, the Gardens is administered by the Australian Government's Department of Agriculture, Water and the Environment. The botanic gardens was added to the Commonwealth Heritage List on 22 June 2004. The botanic gardens is the largest living collection of native Australian flora. The mission of the ANBG is to "study and promote Australia's flora". The gardens maintains a wide variety of botanical resources for researchers and cultivates native plants threatened in the wild. The herbarium code for the Australian National Botanic Gardens is ''CANB''. History When Canberra was being planned in the 1930s, the establishment of the gardens was recommended in a report in 1933 by the Advisory Council of Federal Capital Territory. In 1935, The Dickson Report set forth a framework for their development. A large site fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barbara Lynette Rye
Barbara Lynette Rye is an Australian botanist born in 1952. Barbara Rye has been associated with the Western Australian Herbarium, where her work as a taxonomist has been the source of many new descriptions of plants. The number of taxa recorded as described by women authors is historically very low, of the terrestrial plant species this amount is around three percent, yet in analysis published in 2019 Rye is amongst the ten most prolific women taxonomists. Born in Perth, Western Australia, she spent her childhood investigating the local flora and fauna of the Southwest Australia region, a biodiversity hotspot, and later began studies at the University of Western Australia. Barbara Rye entered the fields of zoology and botany, taking a special interest in genetics and evolutionary biology. The first description of a new species was a '' Darwinia'', a genus of the family Myrtaceae that Rye investigated for her doctoral thesis, separating '' Darwinia capitellata'' from a more widel ...

Thymelaeaceae
The Thymelaeaceae are a cosmopolitan family of flowering plants composed of 50 genera (listed below) and 898 species.Zachary S. Rogers (2009 onwards)A World Checklist of Thymelaeaceae (version 1) Missouri Botanical Garden Website, St. Louis. It was established in 1789 by Antoine Laurent de Jussieu.Antoine Laurent de Jussieu ''Genera Plantarum'', page 76. Herrisant & Barrois, Paris. The Thymelaeaceae are mostly trees and shrubs, with a few vines and herbaceous plants. Description This is not intended as a full botanical description, but only as a few notes on some of the conspicuous or unusual traits of the family when ''Tepuianthus'' is excluded. The bark is usually shiny and fibrous. Attempts to break the stem often result in a strip of bark peeling down the side.Ernst Schmidt, Mervyn Lotter and Warren McCleland The number of stamens is usually once or twice the number of calyx lobes. If twice, then they often occur in two well separated series. Exceptions include ''Gonystylu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peduncle (botany)
In botany, a peduncle is a stalk supporting an inflorescence or a solitary flower, or, after fecundation, an infructescence or a solitary fruit. The peduncle sometimes has bracts (a type of cataphylls) at nodes. The main axis of an inflorescence above the peduncle is the rachis. There are no flowers on the peduncle but there are flowers on the rachis. When a peduncle arises from the ground level, either from a compressed aerial stem or from a subterranean stem (rhizome, tuber, bulb, corm), with few or no bracts except the part near the rachis or receptacle, it is referred to as a scape. The acorns of the pedunculate oak are borne on a long peduncle, hence the name of the tree. See also *Pedicel (botany) *Scape (botany) In botany, a scape is a peduncle arising from a subterranean or very compressed stem, with the lower internodes very long and hence few or no bracts except the part near the rachis or receptacle. Typically it takes the form of a long, leafles ... Re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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, as ...

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''; ...

Stamen
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains ''sporangium, microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna (plant), Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea'' ...

Warrumbungles
The Warrumbungles is a mountain range in the Orana region of New South Wales, Australia. The nearest town is Coonabarabran. The area is easiest accessed from the Newell Highway which is the major road link directly between Melbourne, Victoria and Brisbane, Queensland and cuts across inland New South Wales from the north to the south. As the range is between the moist eastern coastal zone and the dryer plains to the west, it has provided protection for flora and fauna suited to both habitats. There are over 120 bird species identified on the range, including lories and lorikeets, rosellas and parrots. The centre of the range has served as an area of protection for a healthy and content colony of grey kangaroos. These animals have become fairly tame due to constant visitor attention and are easily approached. The Siding Spring Observatory is located on Mount Woorut, an eastern peak. The area has little to no light pollution to disturb astronomical viewing. In 2016, the I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pimelea
''Pimelea'', commonly known as rice flowers, is a genus of plants belonging to the family Thymelaeaceae. There are about 150 species, including 110 in Australia and thirty six in New Zealand. Description Plants in the genus ''Pimelea'' are herbs or small shrubs usually with leaves arranged in opposite pairs. The leaves are usually paler on the lower surface and the 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 has a single ovule and the fruit is usually a 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. The first species Gaertner described was ''Pimelea laevigata'', now known as ''Pimelea prostrata''. The name ''Pimelea'' is from the Ancient Greek word ''pimele'' meaning "fat or "lard", possibly referring ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
