Normanbya
''Normanbya'' is a monotypic genus of palms containing the single species ''Normanbya normanbyi'', which is known by the common name black palm It is endemic to Queensland, Australia and is threatened by habitat destruction. Description ''Normanbya normanbyi'' is visually very similar to the more well-known Foxtail palm but is slightly smaller in all respects. It is a single-stemmed palm with attractive "bushy" fronds, similar to a bottlebrush. It grows to a height of with a small crown of fronds each measuring around long with a petiole about long. The fronds have 75-95 whorled pinnae (leaflets) up to in length, each of which are divided longitudinally into 7-11 radiating segments, giving the fronds the bushy appearance. The pinnae are dark green on the upper surface and silvery underneath and the tips are abruptly truncated (like a fishtail). The inflorescence (grouping of flowers) is a panicle and is borne on the trunk just below the crownshaft. They are around long ...

Odoardo Beccari
Odoardo Beccari (16 November 1843 – 25 October 1920) was an Italian botanist famous for his discoveries in Indonesia, particularly New Guinea, and Australia. He has been called the greatest botanist to ever study Malesia. His author abbreviation is when citing a botanical name. Life Youth and education (1843–1864) Odoardo Beccari was born in Florence as the third child of Giuseppe di Luigi Beccari and the first child of Antonietta Minucci. After he lost his mother in early infancy and his father in 1849, he was brought up by a maternal uncle Minuccio Minucci. From 1853–1861, he attended the prestigious secondary school Real Collegio in Lucca. Here, one of his teachers was abbot Ignazio Mezzetti (1821–1876), a passionate collector of botanical specimens, who inspired him to pursue botany and assemble a herbarium. He later named the genus Mezzettia in his honor. In August 1861, he commenced his studies at the University of Pisa. Here he quickly captured the attent ...

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 (Poaceae), ...

Daintree River
The Daintree River is a river that rises in the Daintree Rainforest near Cape Tribulation in Far North Queensland, Australia. The river is located about northwest of Cairns in the UNESCO World Heritagelisted Wet Tropics of Queensland. The area is now primarily a tourist attraction. Course and features The river rises on the slopes of the Great Dividing Range within the Daintree National Park below Kalkajaka at an elevation of . The river flows in highly meandering course generally north, then east, then south and then east, through the rainforest where the water is fresh. At this convergence point, an abundance of wildlife congregate, particularly fish. The river is joined by two minor tributaries before flowing through the Cairns Marine Park through thick mangrove swamps where the water is highly saline; and then empties into the Coral Sea, north of . The mouth of the Daintree River opens onto a giant sandbar that shifts with each changing tide. The river descends over its ...

Walter Hill (garden Curator)
Walter Hill (1820–1904) was the first curator of the Brisbane Botanic Gardens at Gardens Point in Brisbane, Australia. Personal life Walter Hill was born at Scotsdyke, Dumfriesshire, Scotland, on 31 December 1819, the son of David Hill and Elizabeth Beattie. Scotsdyke is virtually on the border of England and Scotland and is presumably a reference to the moat about south of the village of Canobie (now spelled ''Canonbie''). Hill married Jane Smith, the daughter of John Smith and Jane Brunton, on 16 September 1849 at Holy Trinity Brompton Church, Middlesex, England. They had a daughter Ann (born 25 April 1850 in England, died 1 November 1871 in Brisbane). The family immigrated to Sydney, Australia in 1852 on the "Maitland", where Hill initially tried his luck on the goldfields. In 1854, Hill undertook an expedition (as a botanist) to North Queensland in which most of the party were murdered by Aborigines. After this, Walter accepted the position of superintendent o ...

Basionym
In the scientific name of organisms, basionym or basyonym means the original name on which a new name is based; the author citation of the new name should include the authors of the basionym in parentheses. The term "basionym" is used in both botany and zoology. In zoology, alternate terms such as original combination or protonym are sometimes used instead. Bacteriology uses a similar term, basonym, spelled without an ''i''. Although "basionym" and "protonym" are often used interchangeably, they have slightly different technical definitions. A basionym is the ''correct'' spelling of the original name (according to the applicable nomenclature rules), while a protonym is the ''original'' spelling of the original name. These are typically the same, but in rare cases may differ. Use in botany The term "basionym" is used in botany only for the circumstances where a previous name exists with a useful description, and the '' International Code of Nomenclature for algae, fungi, and plants' ...

Fruit
In botany, a fruit is the seed-bearing structure in flowering plants that is formed from the ovary after flowering. Fruits are the means by which flowering plants (also known as angiosperms) disseminate their seeds. Edible fruits in particular have long propagated using the movements of humans and animals in a symbiotic relationship that is the means for seed dispersal for the one group and nutrition for the other; in fact, humans and many animals have become dependent on fruits as a source of food. Consequently, fruits account for a substantial fraction of the world's agricultural output, and some (such as the apple and the pomegranate) have acquired extensive cultural and symbolic meanings. In common language usage, "fruit" normally means the seed-associated fleshy structures (or produce) of plants that typically are sweet or sour and edible in the raw state, such as apples, bananas, grapes, lemons, oranges, and strawberries. In botanical usage, the term "fruit" also i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stigma (botany)
The stigma () is the receptive tip of a carpel, or of several fused carpels, in the gynoecium of a flower. Description The stigma, together with the style and ovary (typically called the stigma-style-ovary system) comprises the pistil, which is part of the gynoecium or female reproductive organ of a plant. The stigma itself forms the distal portion of the style, or stylodia, and is composed of , the cells of which are receptive to pollen. These may be restricted to the apex of the style or, especially in wind pollinated species, cover a wide surface. The stigma receives pollen and it is on the stigma that the pollen grain germinates. Often sticky, the stigma is adapted in various ways to catch and trap pollen with various hairs, flaps, or sculpturings. The pollen may be captured from the air (wind-borne pollen, anemophily), from visiting insects or other animals ( biotic pollination), or in rare cases from surrounding water (hydrophily). Stigma can vary from long and sle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Staminate
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 vari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pistillate
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 ...

Sessility (botany)
In botany, sessility (meaning "sitting", used in the sense of "resting on the surface") is a characteristic of plant parts (such as flowers and leaves) that have no stalk. Plant parts can also be described as subsessile, that is, not completely sessile. A sessile flower is one that lacks a pedicel (flower stalk). A flower that is not sessile is pedicellate. For example, the genus ''Trillium'' is partitioned into two subgenera, the sessile-flowered trilliums (''Trillium'' subg. ''Sessilium'') and the pedicellate-flowered trilliums. Sessile leaves lack petioles (leaf stalks). A leaf that is not sessile is petiolate. For example, the leaves of most monocotyledons lack petioles. The term sessility is also used in mycology to describe a fungal fruit body that is attached to or seated directly on the surface of the substrate, lacking a supporting stipe or pedicel Pedicle or pedicel may refer to: Human anatomy *Pedicle of vertebral arch, the segment between the transvers ...

Crownshaft
An elongated circumferential leaf base formation present on some species of palm is called a crownshaft. The leaf bases of some pinnate leaved palms (most notable being ''Roystonea regia'' or the royal palm but also including the genera ''Areca'', ''Wodyetia'' and ''Pinanga'') form a sheath at the top of the trunk surrounding the bud where all the subsequent leaves are formed.Riffle, Robert L. and Craft, Paul (2003) ''An Encyclopedia of Cultivated Palms''. Portland: Timber Press. / The crownshaft takes the form of a column above the main trunk and beneath the main crown of leaves and is nothing but the collection of the leaf bases of the plant, all tightly wrapped around one another. It is usually green in color but may be a different color from that of the leaves themselves, including white, blue, red, brownish or orange. Each layer of the crownshaft is a distinct leaf base and is usually made of a tough fibrous material with a feel similar to leather and in many parts of th ...

Panicle
A panicle is a much-branched inflorescence. (softcover ). Some authors distinguish it from a compound spike inflorescence, by requiring that the flowers (and fruit) be pedicellate (having a single stem per flower). The branches of a panicle are often racemes. A panicle may have determinate or indeterminate growth. This type of inflorescence is largely characteristic of grasses such as oat and crabgrass, as well as other plants such as pistachio and mamoncillo. Botanists use the term paniculate in two ways: "having a true panicle inflorescence" as well as "having an inflorescence with the form but not necessarily the structure of a panicle". Corymb A corymb may have a paniculate branching structure, with the lower flowers having longer pedicels than the upper, thus giving a flattish top superficially resembling an umbel. Many species in the subfamily Amygdaloideae, such as hawthorns and rowans, produce their flowers in corymbs. up'' Sorbus glabrescens'' corymb with fruit See ...
