Calamus Radicalis
''Calamus radicalis'', commonly known as vicious hairy mary, is a plant in the palm family Arecaceae endemic to the rainforests of north east Queensland, Australia. Like other species in the genus ''Calamus'', this is a climbing plant with a very long and flexible stem. It uses sharp strong hooks on the fronds and tendrils to attach itself to other vegetation, such as taller established trees, thus gaining support that enables it to grow higher towards the canopy. This species is very similar to '' C. australis'', with which it coexists, but is larger in almost all respects. Description This species has a clustering habit, i.e. several stems are produced from the same base. Stems may reach lengths of up to and a diameter of . The leaves (or fronds) are produced on the youngest part of the stem, and the older sections are bare as the leaves age and fall off (exactly the same process as the more familiar upright palm with a stout stem). The older, leafless part of the stem of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hermann Wendland
Hermann Wendland (October 11, 1825 in Herrenhausen – January 12, 1903 in Hanover) was a German botanist and gardener. He was a noted authority on the family Arecaceae (palms), on which he published a major monograph which formed the basis for the modern classification of the family, including many of the generic names currently in use. The South American palm genus ''Wendlandiella ''Wendlandiella'' is a genus of one species of palms found in Peru, Bolivia and Acre state in Brazil Brazil ( pt, Brasil; ), officially the Federative Republic of Brazil (Portuguese: ), is the largest country in both South America and ...'' is named after him.

Rachis
In biology, a rachis (from the grc, ῥάχις [], "backbone, spine") is a main axis or "shaft". In zoology and microbiology In vertebrates, ''rachis'' can refer to the series of articulated vertebrae, which encase the spinal cord. In this case the ''rachis'' usually forms the supporting axis of the body and is then called the spine or vertebral column. ''Rachis'' can also mean the central shaft of pennaceous feathers. In the gonad of the invertebrate nematode '' Caenorhabditis elegans'', a rachis is the central cell-free core or axis of the gonadal arm of both adult males and hermaphrodites where the germ cells have achieved pachytene and are attached to the walls of the gonadal tube. The rachis is filled with cytoplasm. In botany In plants, a rachis is the main axis of a compound structure. It can be the main stem of a compound leaf, such as in ''Acacia'' or ferns, or the main, flower-bearing portion of an inflorescence above a supporting peduncle. Where it subdivides ...

Highland
Highlands or uplands are areas of high elevation such as a mountainous region, elevated mountainous plateau or high hills. Generally speaking, upland (or uplands) refers to ranges of hills, typically from up to while highland (or highlands) is usually reserved for ranges of low mountains. However, the two terms are sometimes interchangeable. Highlands internationally Probably the best-known area officially or unofficially referred to as ''highlands'' in the Anglosphere is the Scottish Highlands in northern Scotland, the mountainous region north and west of the Highland Boundary Fault. The Highland council area is a local government area in the Scottish Highlands and Britain's largest local government area. Other highland or upland areas reaching 400-500 m or higher in the United Kingdom include the Southern Uplands in Scotland, the Pennines, North York Moors, Dartmoor and Exmoor in England, and the Cambrian Mountains in Wales.

Lowland
Upland and lowland are conditional descriptions of a plain based on elevation above sea level. In studies of the ecology of freshwater rivers, habitats are classified as upland or lowland. Definitions Upland and lowland are portions of plain that are conditionally categorized by their elevation above the sea level. Lowlands are usually no higher than , while uplands are somewhere around to . On unusual occasions, certain lowlands such as the Caspian Depression lie below sea level. Upland habitats are cold, clear and rocky whose rivers are fast-flowing in mountainous areas; lowland habitats are warm with slow-flowing rivers found in relatively flat lowland areas, with water that is frequently colored by sediment and organic matter. These classifications overlap with the geological definitions of "upland" and "lowland". In geology an "upland" is generally considered to be land that is at a higher elevation than the alluvial plain or stream terrace, which are considered ...

Mackay, Queensland
} Mackay () is a city in the Mackay Region on the eastern or Coral Sea coast of Queensland, Australia. It is located about north of Brisbane, on the Pioneer River. Mackay is described as being in either Central Queensland or North Queensland, as these regions are not precisely defined. More generally, the area is known as the Mackay–Whitsunday Region. Mackay is nicknamed the sugar capital of Australia because its region produces more than a third of Australia's sugar. Name The city was named after John Mackay. In 1860, he was the leader of an expedition into the Pioneer Valley. Initially Mackay proposed to name the river Mackay River after his father George Mackay. Thomas Henry Fitzgerald surveyed the township and proposed it was called Alexandra after Princess Alexandra of Denmark, who married Prince Edward (later King Edward VII). However, in 1862 the river was renamed to be the Pioneer River, after in which Queensland Governor George Bowen travelled to the area, and t ...

Type (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost al ...

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 ...

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] |
