Cheilotheca Sleumerana
''Cheilotheca'' is a small genus of myco-heterotrophy, myco-heterotrophic plants in the family Ericaceae. They obtain their nutrients by parasitising fungi in the Russulaceae family. As of 2025, the genus includes four species. Etymology The genus was named by Joseph Dalton Hooker in 1876.Bentham, G., Hooker, J.D. (1876) Genera Plantarum Vol. 2. Reeve & Co., London. The name is derived from the Greek word "cheilos", meaning a lip or an edge. The "theca" is a Latin term, meaning covering or sheath. Together they essentially mean "lipped sheath". Taxonomy Based on morphological analyses, ''Cheilotheca'' has been placed in the Ericaceae subfamily Monotropoideae.Kron, K.A., Judd, W.S., Stevens, P.F., Crayn, D.M., Anderberg, A.A., Gadek, P.A., Quinn, C.J., Luteyn, J.L. 2002.

Joseph Dalton Hooker
Sir Joseph Dalton Hooker (30 June 1817 – 10 December 1911) was a British botanist and explorer in the 19th century. He was a founder of geographical botany and Charles Darwin's closest friend. For 20 years he served as director of the Royal Botanical Gardens, Kew, succeeding his father, William Jackson Hooker, and was awarded the highest honours of British science. Biography Early years Hooker was born in Halesworth, Suffolk, England. He was the second son of Maria Sarah Turner, eldest daughter of the banker Dawson Turner and sister-in-law of Francis Palgrave, and the famous botanist Sir William Jackson Hooker, Regius Professor of Botany, Glasgow, Regius Professor of Botany. From the age of seven, Hooker attended his father's lectures at the University of Glasgow, taking an early interest in plant geography, plant distribution and the voyages of explorers like Captain James Cook. He was educated at the High School of Glasgow, Glasgow High School and went on to study med ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

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] |
Ericaceae
The Ericaceae () are a Family (biology), family of flowering plants, commonly known as the heath or heather family, found most commonly in acidic and infertile growing conditions. The family is large, with about 4,250 known species spread across 124 genera, making it the 14th most species-rich family of flowering plants. The many well known and economically important members of the Ericaceae include the cranberry, blueberry, huckleberry, rhododendron (including azaleas), and various common heaths and heathers (''Erica (plant), Erica'', ''Cassiope'', ''Daboecia'', and ''Calluna'' for example). Description The Ericaceae contain a morphologically diverse range of taxa, including Herbaceous plant, herbs, chamaephyte, dwarf shrubs, shrubs, and trees. Their leaves are usually evergreen, alternate or whorled, simple and without stipules. Their flowers are Plant sexuality#Individual plant sexuality, hermaphrodite and show considerable variability. The petals are often fused (sympetalous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russulaceae
The Russulaceae are a diverse family (biology), family of fungi in the order Russulales, with roughly 1,900 known species and a worldwide distribution. They comprise the Russula, brittlegills and the milk-caps, well-known mushroom-forming fungi that include some Edible fungi, edible species. These Lamella (mycology), gilled mushrooms are characterised by the brittle trama (mycology), flesh of their basidiocarp, fruitbodies. In addition to these typical agaricoid forms, the family contains species with fruitbodies that are laterally striped (Pleurotoid fungi, pleurotoid), closed (secotioid or Gasteroid fungi, gasteroid), or crust-like (Corticioid fungi, corticioid). Molecular phylogenetics has demonstrated close affinities between species with very different fruitbody types and has discovered new, distinct Lineage (evolution), lineages. An important group of root-symbiosis, symbiotic ectomycorrhizal fungi in forests and shrublands around the world includes ''Lactifluus'', ''Multi ...

Theca
In biology, a theca (: thecae) is a sheath or a covering. Botany In botany, the theca is related to plant's flower anatomy. The theca of an angiosperm consists of a pair of microsporangia that are adjacent to each other and share a common area of dehiscence called the stomium. Larry Hufford, "The origin and early evolution of angiosperm stamens" i''The Anther: form, function, and phylogeny'' William G. D'Arcy and Richard C. Keating (editors), Cambridge University Press, 1996, 351pp, p.60, (from Google Books) Any part of a microsporophyll that bears microsporangia is called an anther. Most anthers are formed on the apex of a filament. An anther and its filament together form a typical (or filantherous) stamen, part of the male floral organ. The typical anther is bilocular, i.e. it consists of two thecae. Each theca contains two microsporangia, also known as pollen sacs. The microsporangia produce the microspores, which for seed plants are known as pollen grains. If the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monotropa
''Monotropa'' is a genus of four species of herbaceous perennial flowering plants. The genus was formerly classified in the family Monotropaceae and presently classified in Ericaceae. They are native to temperate regions of the Northern Hemisphere and are generally rare. Unlike most plants they do not have chlorophyll and therefore are non-photosynthetic; rather, they are myco-heterotrophs that obtain food through parasitism on subterranean fungi. Because they do not need any sunlight to live, they can live in very dark sites such as the floor of deep forest A forest is an ecosystem characterized by a dense ecological community, community of trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, .... The name "Monotropa" is Greek for "one turn" as every plant has one large turn near the top of the plant. Species The genus consists of the following three species: '' Mo ...
