Pinedrops
''Pterospora'', commonly known as pinedrops, woodland pinedrops, Albany beechdrops, or giant bird's nest, is a North American genus in the subfamily Monotropoideae of the Ericaceae, heath family, and includes only the species ''Pterospora andromedea''. It grows as a mycoheterotroph (relying on fungi rather than photosynthesis for nutrients) in Pinophyta, coniferous or mixed forests. It is widespread across much of Canada as well as the western and northeastern United States to Mexico. Along with ''Monotropa'' it is one of the more frequently encountered genera of the Monotropoideae. Description The visible portion of ''Pterospora andromedea'' is a fleshy, unbranched, reddish to yellowish flower spike (raceme) in height, though it has been reported to occasionally attain a height of . The above-ground stalks (inflorescences) resemble an emerging asparagus spear in shape and are usually found in small clusters between June and August. The inflorescences are hairy and noticeabl ...

Myco-heterotrophy
Myco-heterotrophy (from Greek , , and ) is a symbiotic relationship between certain kinds of plants and fungi, in which the plant gets all or part of its food from parasitism upon fungi rather than from photosynthesis. A myco-heterotroph is the parasitic plant partner in this relationship. Myco-heterotrophy is considered a kind of cheating relationship and myco-heterotrophs are sometimes informally referred to as "mycorrhizal cheaters". This relationship is sometimes referred to as mycotrophy, though this term is also used for plants that engage in mutualistic mycorrhizal relationships. Relationship between myco-heterotrophs and host fungi Full (or obligate) myco-heterotrophy exists when a non-photosynthetic plant (a plant largely lacking in chlorophyll or otherwise lacking a functional photosystem) gets all of its food from the fungi that it parasitizes. Partial (or facultative) myco-heterotrophy exists when a plant is capable of photosynthesis, but parasitizes fung ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Name
In biology, a common name of a taxon or organism (also known as a vernacular name, English name, colloquial name, country name, popular name, or farmer's name) is a name that is based on the normal language of everyday life; and is often contrasted with the scientific name for the same organism, which is often based in Latin. A common name is sometimes frequently used, but that is not always the case. In chemistry, IUPAC defines a common name as one that, although it unambiguously defines a chemical, does not follow the current systematic naming convention, such as acetone, systematically 2-propanone, while a vernacular name describes one used in a lab, trade or industry that does not unambiguously describe a single chemical, such as copper sulfate, which may refer to either copper(I) sulfate or copper(II) sulfate. Sometimes common names are created by authorities on one particular subject, in an attempt to make it possible for members of the general public (including s ...

Morphology (biology)
Morphology (from Ancient Greek μορφή (morphḗ) "form", and λόγος (lógos) "word, study, research") is the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, color, pattern, size), as well as the form and structure of internal parts like bones and organs, i.e., anatomy. This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of the overall structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Fried ...

Sarcodes
''Sarcodes'' is a monotypic genus of flowering plants in the heath family (Ericaceae) native to northwest North America, containing the single species ''Sarcodes sanguinea'', commonly called the snow plant or snow flower. It is a parasitic plant that derives sustenance and nutrients from mycorrhizal fungi that attach to tree roots. Lacking chlorophyll, it is unable to photosynthesize. Ectomycorrhizal (EM) symbioses involve a mutualism between a plant root and a fungus; the plant provides fixed carbon to the fungus and in return, the fungus provides mineral nutrients, water, and protection from pathogens to the plant. The snow plant takes advantage of this mutualism by tapping into the network and stealing sugars from the photosynthetic partner by way of the fungus. This is known as mycoheterotrophy. The snow plant is host-specific and can only form relationships with the ectomycorrhizal Basidiomycete '' Rhizopogon ellenae.'' The plant's aboveground tissue is its inflorescence, ...

Monotypic Taxon
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 Genus, 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 o ...

Amos Eaton
Amos Eaton (May 17, 1776 – May 10, 1842) was an American botany, botanist, geologist, and educator who is considered the founder of the modern scientific prospectus in education, which was a radical departure from the American liberal arts tradition of classics, theology, lecture, and recitation. Eaton co-founded the Rensselaer Polytechnic Institute, Rensselaer School in 1824 with Stephen van Rensselaer, Stephen van Rensselaer III "in the application of science to the common purposes of life". His books in the eighteenth century were among the first published for which a systematic treatment of the United States was attempted, and in a language that all could read. His teaching laboratory for botany in the 1820s was the first of its kind in the country. Eaton's popular lectures and writings inspired numerous thinkers, in particular women, whom he encouraged to attend his public talks on experimental philosophy. Emma Willard would found the Emma Willard School, Troy Female Sem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
5 Pterospora Andromedea - John Lindley - Collectanea Botanica (1821)
5 (five) is a number, numeral and digit. It is the natural number, and cardinal number, following 4 and preceding 6, and is a prime number. Humans, and many other animals, have 5 digits on their limbs. Mathematics 5 is a Fermat prime, a Mersenne prime exponent, as well as a Fibonacci number. 5 is the first congruent number, as well as the length of the hypotenuse of the smallest integer-sided right triangle, making part of the smallest Pythagorean triple ( 3, 4, 5). 5 is the first safe prime and the first good prime. 11 forms the first pair of sexy primes with 5. 5 is the second Fermat prime, of a total of five known Fermat primes. 5 is also the first of three known Wilson primes (5, 13, 563). Geometry A shape with five sides is called a pentagon. The pentagon is the first regular polygon that does not tile the plane with copies of itself. It is the largest face any of the five regular three-dimensional regular Platonic solid can have. A conic is determined ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pine
A pine is any conifer tree or shrub in the genus ''Pinus'' () of the family Pinaceae. ''Pinus'' is the sole genus in the subfamily Pinoideae. ''World Flora Online'' accepts 134 species-rank taxa (119 species and 15 nothospecies) of pines as current, with additional synonyms, and ''Plants of the World Online'' 126 species-rank taxa (113 species and 13 nothospecies), making it the largest genus among the conifers. The highest species diversity of pines is found in Mexico. Pines are widely species distribution, distributed in the Northern Hemisphere; they occupy large areas of boreal forest, but are found in many habitats, including the Mediterranean Basin, and dry tropical forests in southeast Asia and Central America. Wood from pine trees is one of the most extensively used types of timber, and some pines are widely used as Christmas trees.

Rhizopogon Subg
''Rhizopogon'' is a genus of ectomycorrhizal basidiomycetes in the family Rhizopogonaceae. Species form hypogeous sporocarps commonly referred to as "false truffles". The general morphological characters of ''Rhizopogon'' sporocarps are a simplex or duplex peridium surrounding a loculate gleba that lacks a columnella. Basidiospores are produced upon basidia that are borne within the fungal hymenium that coats the interior surface of gleba locules. The peridium is often adorned with thick mycelial cords, also known as rhizomorphs, that attach the sporocarp to the surrounding substrate. The scientific name ''Rhizopogon'' is Greek for 'root' (Rhiz-) 'beard' (-pogon) and this name was given in reference to the rhizomorphs found on sporocarps of many species. ''Rhizopogon'' species are primarily found in ectomycorrhizal association with trees in the family Pinaceae and are especially common symbionts of pine, fir, and Douglas fir trees. Through their ectomycorrhizal relationships ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
