Acradenia
''Acradenia'' is a genus of two species of tree or shrub in the family Rutaceae and is endemic to Australia. These plants have leaves that are trifoliate, arranged in opposite pairs and flowers that have five sepals, five petals and usually ten stamens of unequal lengths. Description Plants in the genus ''Acradenia'' are evergreen trees, sometimes shrubs with trifoliate leaves arranged in opposite pairs and lacking domatia. The flowers are arranged in panicles in leaf axils or on the ends of branchlets. The flowers are bisexual usually with five (rarely six) sepals and petals. The sepals are long, joined at the base and remain attached to the fruit. The petals overlap at the base and there are twice as many stamens as petals, usually alternating in length. There are usually five carpels in each ovary and two ovules in each locule. The fruit has up to five follicles joined at the base, each follicle with a single, smooth brown seed about long.

Richard Kippist
Richard Kippist (1812–1882) was an English botanist and librarian. Life Kippist was born in Stoke Newington, London, on 11 June 1812. He worked as a clerk in the office of Joseph Woods, F.L.S., architect, with whom he shared an interest in botany. He was employed by the Linnean Society from 1830, holding the position of librarian from 1842 to 1881. His special interest was Australian flora, and he advised George Bentham, Ferdinand von Mueller and others on this subject. His published works include "On ''Jansonia'', a new genus of Leguminosae from Western Australia" and "On ''Acradenia'', a new genus of Diosmae" in the ''Transactions'' of the society, describing the genera ''Jansonia'' (''Gastrolobium'') and '' Acradenia''. He assisted with the editing of Wood's ''The Tourists Flora'', published in 1830. His important papers include one on the discovery of spiral cells in the seeds of the family Acanthaceae. Kippist was a founding member of The Microscopical Society of Londo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

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.

Follicle (fruit)
In botany, a follicle is a dry unilocular fruit formed from one carpel, containing two or more seeds. It is usually defined as dehiscing by a suture in order to release seeds, for example in ''Consolida'' (some of the larkspurs), peony and milkweed (''Asclepias''). Some difficult cases exist however, so that the term indehiscent follicle is sometimes used, for example with the genus ''Filipendula'', which has indehiscent fruits that could be considered intermediate between a (dehiscent) follicle and an (indehiscent) achene. An aggregate fruit that consists of follicles may be called a follicetum. Examples include hellebore, aconite, ''Delphinium'', ''Aquilegia'' or the family Crassulaceae, where several follicles occur in a whorl on a shortened receptacle, or ''Magnolia'', which has many follicles arranged in a spiral on an elongated receptacle. The follicles of some species dehisce by the ventral suture (as in ''Banksia''), or by the dorsal suture (as in ''Magnolia'').Kapil, R. ...

Locule
A locule (plural locules) or loculus (plural loculi) (meaning "little place" in Latin) is a small cavity or compartment within an organ or part of an organism (animal, plant, or fungus). In angiosperms (flowering plants), the term ''locule'' usually refers to a chamber within an Ovary (plants), ovary (gynoecium or carpel) of the flower and fruits. Depending on the number of locules in the ovary, fruits 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. The term may also refer to chambers within anthers containing pollen. In Ascomycete fungi, locules are chambers within the hymenium in which the perithecium, perithecia develop.

Ovule
In seed plants, the ovule is the structure that gives rise to and contains the female reproductive cells. It consists of three parts: the ''integument'', forming its outer layer, the ''nucellus'' (or remnant of the megasporangium), and the female gametophyte (formed from a haploid megaspore) in its center. The female gametophyte — specifically termed a ''megagametophyte''— is also called the ''embryo sac'' in angiosperms. The megagametophyte produces an egg cell for the purpose of fertilization. The ovule is a small structure present in the ovary. It is attached to the placenta by a stalk called a funicle. The funicle provides nourishment to the ovule. Location within the plant In flowering plants, the ovule is located inside the portion of the flower called the gynoecium. The ovary of the gynoecium produces one or more ovules and ultimately becomes the fruit wall. Ovules are attached to the placenta in the ovary through a stalk-like structure known as a ''funiculus'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
