Philesia
''Philesia'' is a South American genus of flowering plants in the monocot family Philesiaceae first described as a genus in 1789. The native name is Coicopihue. There is only one known species in this genus, ''Philesia magellanica'', which is native to southern Chile (from Los Ríos to Magallanes regions) and southern Argentina. This species is, unusually for a monocot, a suckering shrub, growing to tall and spreading by stolons. The leaves are linear, 15–35 mm long and 3–8 mm broad, glossy green above, and with two white stomatal bands below. The flowers have six tepal A tepal is one of the outer parts of a flower (collectively the perianth). The term is used when these parts cannot easily be classified as either sepals or petals. This may be because the parts of the perianth are undifferentiated (i.e. of very ...s, the outer three short, 15–22 mm long, the inner three long, 45–65 mm long; they are mostly pink, but some darker, more purple variations have been reco ...

Liliales
Liliales is an order (biology), order of monocotyledonous flowering plants in the Angiosperm Phylogeny Group and Angiosperm Phylogeny Web List of systems of plant classification, system, within the lilioid monocots. This order of necessity includes the family (biology), family Liliaceae. The APG III system (2009) places this order in the monocot clade. In APG III, the family Luzuriagaceae is combined with the family Alstroemeriaceae and the family Petermanniaceae is recognized. Both the order Lililiales and the family Liliaceae have had a widely disputed history, with the circumscription (taxonomy), circumscription varying greatly from one taxonomist to another. Previous members of this order, which at one stage included most monocots with conspicuous tepals and lacking starch in the endosperm are now distributed over three orders, Liliales, Dioscoreales and Asparagales, using predominantly molecular phylogenetics. The newly delimited Liliales is monophyletic, with ten families. W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philesiaceae
Philesiaceae is a family of flowering plants, including two genera, each with a single species. The members of the family are woody shrubs or vines endemic to southern Chile. The APG III system, of 2009 (unchanged from the APG II system of 2003 and the APG system, of 1998) places the family in the order Liliales, in the clade monocots. They are a sister to the family Ripogonaceae which is endemic to Australia, New Zealand and New Guinea.

Magallanes Region
The Magallanes Region (), officially the Magallanes y la Antártica Chilena Region () or Magallanes and the Chilean Antarctica Region in English, is one of Chile's 16 first order administrative divisions. It is the southernmost, largest, and second least populated Regions of Chile, region of Chile. It comprises four provinces of Chile, provinces: Última Esperanza Province, Última Esperanza, Magallanes Province, Magallanes, Tierra del Fuego Province, Chile, Tierra del Fuego, and Antártica Chilena. The region takes its name from the Strait of Magellan which runs through it, which was in turn named after Ferdinand Magellan, the leader of the European expedition that discovered it. Magallanes's geographical features include Torres del Paine, Cape Horn, Tierra del Fuego island, and the Strait of Magellan. It also includes the Chilean Antarctic Territory, Antarctic territory claimed by Chile. Despite its large area, much of the land in the region is rugged or closed off for sheep f ...

Monotypic Liliales Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical system. ...

Tepal
A tepal is one of the outer parts of a flower (collectively the perianth). The term is used when these parts cannot easily be classified as either sepals or petals. This may be because the parts of the perianth are undifferentiated (i.e. of very similar appearance), as in ''Magnolia'', or because, although it is possible to distinguish an outer whorl of sepals from an inner whorl of petals, the sepals and petals have similar appearance to one another (as in ''Lilium''). The term was first proposed by Augustin Pyramus de Candolle in 1827 and was constructed by analogy with the terms "petal" and "sepal". (De Candolle used the term ''perigonium'' or ''perigone'' for the tepals collectively; today, this term is used as a synonym for ''perianth''.) p. 39. Origin Undifferentiated tepals are believed to be the ancestral condition in flowering plants. For example, ''Amborella'', which is thought to have separated earliest in the evolution of flowering plants, has flowers with undiffer ...

Stomata
In botany, a stoma (: stomata, from Greek ''στόμα'', "mouth"), also called a stomate (: stomates), is a pore found in the epidermis of leaves, stems, and other organs, that controls the rate of gas exchange between the internal air spaces of the leaf and the atmosphere. The pore is bordered by a pair of specialized parenchyma cells known as guard cells that regulate the size of the stomatal opening. The term is usually used collectively to refer to the entire stomatal complex, consisting of the paired guard cells and the pore itself, which is referred to as the stomatal aperture. Air, containing oxygen, which is used in respiration, and carbon dioxide, which is used in photosynthesis, passes through stomata by gaseous diffusion. Water vapour diffuses through the stomata into the atmosphere as part of a process called transpiration. Stomata are present in the sporophyte generation of the vast majority of land plants, with the exception of liverworts, as well as so ...

Stolon
In biology, a stolon ( from Latin ''wikt:stolo, stolō'', genitive ''stolōnis'' – "branch"), also known as a runner, is a horizontal connection between parts of an organism. It may be part of the organism, or of its skeleton. Typically, animal stolons are exoskeletons (external skeletons). In botany In botany, stolons are plant stems which grow at the soil surface or just below ground that form adventitious roots at the Node (botany), nodes, and new plants from the buds. Stolons are often called runners. Rhizomes, in contrast, are root-like stems that may either grow horizontally at the soil surface or in other orientations underground. Thus, not all horizontal stems are called stolons. Plants with stolons are called stoloniferous. A stolon is a plant propagation strategy and the complex of individuals formed by a mother plant and all its Cloning, clones produced from stolons form a single genetic individual, a genet (biology), genet. Morphology Stolons may have long or shor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shrub
A shrub or bush is a small to medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen. They are distinguished from trees by their multiple Plant stem, stems and shorter height, less than tall. Small shrubs, less than tall are sometimes termed as subshrubs. Many botany, botanical groups have species that are shrubs, and others that are trees and herbaceous plants instead. Some define a shrub as less than and a tree as over 6 m. Others use as the cutoff point for classification. Many trees do not reach this mature height because of hostile, less than ideal growing conditions, and resemble shrub-sized plants. Others in such species have the potential to grow taller in ideal conditions. For longevity, most shrubs are classified between Perennial plant, perennials and trees. Some only last about five years in good conditions. Others, usually larger and more woody, live beyond ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Philibert Commerson
Philibert Commerson (; 18 November 1727 – 14 March 1773), sometimes spelled Commerçon by contemporaries, was a French naturalist, best known for accompanying Louis Antoine de Bougainville on his voyage of circumnavigation in 1766–1769. Biography Commerson was born at Châtillon-les-Dombes in France. He studied in Montpellier, and for a time was a practicing physician. He was in contact with Carl Linnaeus, who encouraged him to study fish of the Mediterranean. Commerson returned to live at Châtillon-les-Dombes, where he occupied himself in creating a botanical garden in 1758. After the death of his wife in 1762, he moved to Paris. In 1766, Commerson joined Bougainville on his voyage of circumnavigation after being recommended for the position of naturalist by the Paris Academy of Sciences. He had previously drawn up an extensive programme of nature studies for the Marine Ministry, in which he elaborated the "three natural kingdoms" which a naturalist should investiga ...
