Philotheca Spicata
''Philotheca'' is a genus of about fifty species of flowering plants in the family Rutaceae. Plants in this genus are shrubs with simple leaves arranged alternately along the stems, flowers that usually have five sepals, five petals and ten stamens that curve inwards over the ovary. All species are endemic to Australia and there are species in every state, but not the Northern Territory. Description Plants in the genus ''Philotheca'' are shrubs that are either glabrous or have tiny, simple hairs. The leaves are arranged alternately along the stems, narrow oblong to almost cylindrical and sessile or on a very short petiole. From a single to many flowers are arranged in leaf axils or on the ends of the branchlets. The flowers have five sepals and five petals (except in '' P. virgata'' which has four). The sepals are free from each other and the petals usually overlap at their bases. There are ten stamens that curve inwards over the ovary with anthers that have an appendage calle ...

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 ''glabrescent ...

Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia le ...

Nomen Illegitimum
''Nomen illegitimum'' (Latin for illegitimate name) is a technical term, used mainly in botany. It is usually abbreviated as ''nom. illeg.'' Although the International Code of Nomenclature for algae, fungi, and plants uses Latin terms for other kinds of name (e.g. ''nomen conservandum'' for " conserved name"), the glossary defines the English phrase "illegitimate name" rather than the Latin equivalent.''Melbourne Code''Glossary/ref> However, the Latin abbreviation is widely used by botanists and mycologists. A superfluous name is often an illegitimate name. Again, although the glossary defines the English phrase, the Latin equivalent ''nomen superfluum'', abbreviated ''nom. superfl.'' is widely used by botanists. Definition A ''nomen illegitimum'' is a validly published name, but one that contravenes some of the articles laid down by the International Botanical Congress.

Linnean Society Of London
The Linnean Society of London is a learned society dedicated to the study and dissemination of information concerning natural history, evolution, and taxonomy. It possesses several important biological specimen, manuscript and literature collections, and publishes academic journals and books on plant and animal biology. The society also awards a number of prestigious medals and prizes. A product of the 18th-century enlightenment, the Society is the oldest extant biological society in the world and is historically important as the venue for the first public presentation of the theory of evolution by natural selection on 1 July 1858. The patron of the society was Queen Elizabeth II. Honorary members include: King Charles III of Great Britain, Emeritus Emperor Akihito of Japan, King Carl XVI Gustaf of Sweden (both of latter have active interests in natural history), and the eminent naturalist and broadcaster Sir David Attenborough.

Port Jackson
Port Jackson, consisting of the waters of Sydney Harbour, Middle Harbour, North Harbour and the Lane Cove and Parramatta Rivers, is the ria or natural harbour of Sydney, New South Wales, Australia. The harbour is an inlet of the Tasman Sea (part of the South Pacific Ocean). It is the location of the Sydney Opera House and Sydney Harbour Bridge. The location of the first European settlement and colony on the Australian mainland, Port Jackson has continued to play a key role in the history and development of Sydney. Port Jackson, in the early days of the colony, was also used as a shorthand for Sydney and its environs. Thus, many botanists, see, e.g, Robert Brown's ''Prodromus Florae Novae Hollandiae et Insulae Van Diemen'', described their specimens as having been collected at Port Jackson. Many recreational events are based on or around the harbour itself, particularly Sydney New Year's Eve celebrations. The harbour is also the starting point of the Sydney to Hobart Yacht ...

Capsule (botany)
In botany a capsule is a type of simple, dry, though rarely fleshy dehiscent fruit produced by many species of angiosperms (flowering plants). Origins and structure The capsule (Latin: ''capsula'', small box) is derived from a compound (multicarpeled) ovary. A capsule is a structure composed of two or more carpels. In (flowering plants), the term locule (or cell) is used to refer to a chamber within the fruit. Depending on the number of locules in the ovary, fruit can be classified as uni-locular (unilocular), bi-locular, tri-locular or multi-locular. The number of locules present in a gynoecium may be equal to or less than the number of carpels. The locules contain the ovules or seeds and are separated by septa. Dehiscence In most cases the capsule is dehiscent, i.e. at maturity, it splits apart (dehisces) to release the seeds within. A few capsules are indehiscent, for example those of ''Adansonia digitata'', ''Alphitonia'', and '' Merciera''. Capsules are often classifie ...

Gynoecium
Gynoecium (; ) is most commonly used as a collective term for the parts of a flower that produce ovules and ultimately develop into the fruit and seeds. The gynoecium is the innermost whorl of a flower; it consists of (one or more) ''pistils'' and is typically surrounded by the pollen-producing reproductive organs, the stamens, collectively called the androecium. The gynoecium is often referred to as the "female" portion of the flower, although rather than directly producing female gametes (i.e. egg cells), the gynoecium produces megaspores, each of which develops into a female gametophyte which then produces egg cells. The term gynoecium is also used by botanists to refer to a cluster of archegonia and any associated modified leaves or stems present on a gametophyte shoot in mosses, liverworts, and hornworts. The corresponding terms for the male parts of those plants are clusters of antheridia within the androecium. Flowers that bear a gynoecium but no stamens are called ''pi ...

Anthers
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 ''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'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea''). The androecium in var ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
