Pomaderris Crassifolia
''Pomaderris crassifolia'' is a species of flowering plant in the family Rhamnaceae and is endemic to eastern Australia. It is a shrub with hairy young stems, egg-shaped or elliptic leaves, and clusters of cream-coloured or yellow flowers. Description ''Pomaderris crassifolia'' is a shrub that typically grows to a height of , its young stems woolly-hairy. The leaves are egg-shaped to elliptic, mostly long and wide on a petiole long with egg-shaped stipules long at the base. The upper surface of the leaves is glabrous and the lower surface densely covered with woolly hairs. The flowers are borne in clusters or twenty to more than fifty, the clusters long on the ends of branchlets and are cream-coloured and densely hairy. The floral cup is about in diameter and the sepals are long but there are usually no petals. Flowering occurs in August and September. Taxonomy ''Pomaderris crassifolia'' was first formally described in 1997 by Neville Grant Walsh and Fiona Coates and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fiona Coates
Fiona is a feminine given name. The name is associated with the Gaelic traditions of Ireland and Scotland (through the poetry of James Macpherson), but has also become popular in England.. It can be considered either a Latinised form of the Gaelic word ''fionn'', meaning "white", "fair", or an Anglicisation of the Irish name ''Fíona'' (derived from an element meaning "vine"). The Scottish Gaelic feminine name ''Fionnghal'' (and variants) is sometimes equated with ''Fiona''. In ninth-century Welsh and Breton language 'Fion' (today: 'ffion') referred to the foxglove species and is also a female given name as in Ffion Hague. ''Fiona'' was the 49th most popular name for baby girls born in 2008 in Germany. ''Fiona'' was tied for third place in the ranking of most popular names for baby girls born in Liechtenstein in 2008. The name was the 347th most popular name for girls born in the United States in 2008, where it has ranked among the top 1,000 most popular names for girls since 19 ...

Rhamnaceae
The Rhamnaceae are a large family of flowering plants, mostly trees, shrubs, and some vines, commonly called the buckthorn family. Rhamnaceae is included in the order Rosales. The family contains about 55 genera and 950 species. The Rhamnaceae have a worldwide distribution, but are more common in the subtropical and tropical regions. The earliest fossil evidence of Rhamnaceae is from the Late Cretaceous. Fossil flowers have been collected from the Upper Cretaceous of Mexico and the Paleocene of Argentina. Leaves of family Rhamnaceae members are simple, i.e., the leaf blades are not divided into smaller leaflets.Flowering Plants of the Santa Monica Mountains, Nancy Dale, 2nd Ed. 2000, p. 166 Leaves can be either alternate or opposite. Stipules are present. These leaves are modified into spines in many genera, in some (e.g. '' Paliurus spina-christi'' and ''Colletia cruciata'') spectacularly so. ''Colletia'' stands out by having two axillary buds instead of one, one developing i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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 ...

Stipule
In botany, a stipule is an outgrowth typically borne on both sides (sometimes on just one side) of the base of a leafstalk (the petiole). Stipules are considered part of the anatomy of the leaf of a typical flowering plant, although in many species they may be inconspicuous —or sometimes entirely absent, and the leaf is then termed ''exstipulate''. (In some older botanical writing, the term "stipule" was used more generally to refer to any small leaves or leaf-parts, notably prophylls.) The word ''stipule'' was coined by Linnaeus''Concise English Dictionary'' Wordsworth Editions Ltd. 1994, from Latin ''stipula'', straw, stalk. Types of stipules General characteristics The position of stipules on a plant varies widely from species to species, though they are often located near the base of a leaf. Stipules are most common on dicotyledons, where they appear in pairs alongside each leaf. Some monocotyledon plants display stipule-like structures, but only display one per leaf ...

Glabrous
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 ''glabres ...

Floral Cup
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''; in roses ...

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, ...

Muelleria (journal)
''Muelleria'' is a peer-reviewed scientific journal on botany published by the Royal Botanic Gardens Melbourne. It focuses on topics relating to plants, algae, and fungi in the southern hemisphere and Australia in particular. The journal was named in honour of Victorian Government botanist Ferdinand von Mueller. ''Muelleria'' commenced publication in 1955 with funding from the Maud Gibson Trust. The trust was initiated in 1945 following the donation of £20,000 by Maud Gibson, a daughter of William Gibson, founder of the Foy & Gibson department store chain. ''Muelleria'' was one of a number of botanical journals initiated by Australian herbaria after World War II, reflecting the increased level of botanical research undertaken at this time. James Hamlyn Willis was the editor of the three initial issues. Editors-in-chief The following persons have been or are editor-in-chief: * James Hamlyn Willis (Vol 1. 1956–1967) * Rex Bertram Filson (Vol. 2-Vol. 3, no. 3. 1969–1976) * ...

Disjunct Distribution
In biology, a taxon with a disjunct distribution is one that has two or more groups that are related but considerably separated from each other geographically. The causes are varied and might demonstrate either the expansion or contraction of a species' range. Range fragmentation Also called range fragmentation, disjunct distributions may be caused by changes in the environment, such as mountain building and continental drift or rising sea levels; it may also be due to an organism expanding its range into new areas, by such means as rafting, or other animals transporting an organism to a new location (plant seeds consumed by birds and animals can be moved to new locations during bird or animal migrations, and those seeds can be deposited in new locations in fecal matter). Other conditions that can produce disjunct distributions include: flooding, or changes in wind, stream, and current flows, plus others such as anthropogenic introduction of alien introduced species either acci ...
