Gastrodia Agnicellus
''Gastrodia agnicellus'' is a species of orchid in the genus ''Gastrodia'', found in Madagascar and described in '' Curtis's Botanical Magazine '' by Johan Hermans in 2020. It has been said to be "the ugliest orchid in the world", with "brown, fleshy and grotesque" flowers. Like all species in its genus, it is leafless and mycotrophic. ''Agnicellus'' means "little lamb" or "lambkin". The name "refers to the woolly covering on the rhizome, the ear-like petals and also alludes to the name of the botanical artist who brought the new species to life in her drawing." For her work on this species the illustrator, Deborah Lambkin, won the 2020 Margaret Flockton Award, an annual award "for excellence in scientific botanical illustration" made by the Royal Botanic Garden, Sydney. Distribution and habitat ''Gastrodia agnicellus'' has only been found in the Vatovavy-Fitovinany region in the southeast of Madagascar. It lives in the shade in the forests of Madagscar, often under leaf lit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Orchid
Orchids are plants that belong to the family Orchidaceae (), a diverse and widespread group of flowering plants with blooms that are often colourful and fragrant. Along with the Asteraceae, they are one of the two largest families of flowering plants. The Orchidaceae have about 28,000 currently accepted species, distributed in about 763 genera. (See ''External links'' below). The determination of which family is larger is still under debate, because verified data on the members of such enormous families are continually in flux. Regardless, the number of orchid species is nearly equal to the number of bony fishes, more than twice the number of bird species, and about four times the number of mammal species. The family encompasses about 6–11% of all species of seed plants. The largest genera are ''Bulbophyllum'' (2,000 species), ''Epidendrum'' (1,500 species), ''Dendrobium'' (1,400 species) and ''Pleurothallis'' (1,000 species). It also includes ''Vanilla'' (the genus of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gastrodia
''Gastrodia'', commonly known as potato orchids or as 天麻属 (tian ma shu), is a genus of terrestrial leafless orchids in the family Orchidaceae, about ninety of which have been described. Orchids in this genus have fleshy, upright stems and small to medium-sized resupinate flowers with narrow sepals and petals. They are native to Asia (China, the Russian Far East, Japan, Korea, Southeast Asia, the Indian Subcontinent), Australia, New Zealand, central Africa, and various islands of the Indian and Pacific Oceans. Description Orchids in the genus ''Gastrodia'' are leafless, terrestrial, mycotrophic herbs with a fleshy, underground rhizome and an upright flowering stem with a few to many brownish, resupinate flowers. The sepals and petals are fused to form a bell-shaped or irregular tube with the tips free. The petals are usually much smaller than the sepals and the labellum has three lobes and is fully enclosed in the tube. Taxonomy The genus ''Gastrodia'' was first formally ...

Madagascar
Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa across the Mozambique Channel. At Madagascar is the world's List of island countries, second-largest island country, after Indonesia. The nation is home to around 30 million inhabitants and consists of the island of Geography of Madagascar, Madagascar (the List of islands by area, fourth-largest island in the world), along with numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 90 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of wildlife of Madagascar, its wildlife is endemic. Human settlement of Madagascar occurred during or befo ...

Curtis's Botanical Magazine
''The Botanical Magazine; or Flower-Garden Displayed'', is an illustrated publication which began in 1787. The longest running botanical magazine, it is widely referred to by the subsequent name ''Curtis's Botanical Magazine''. Each of the issues contains a description, in formal yet accessible language, and is renowned for featuring the work of two centuries of botanical illustrators. Many plants received their first publication on the pages, and the description given was enhanced by the keenly detailed illustrations. History and profile The first issue, published on 1 February 1787, was begun by William Curtis, as both an illustrated gardening and botanical journal. Curtis was an apothecary and botanist who held a position at Kew Gardens, who had published the highly praised (but poorly sold) ''Flora Londinensis'' a few years before. The publication familiarized its readers with ornamental and exotic plants, which it presented in octavo format. Artists who had previously giv ...

Mycotroph
A mycotroph is a plant that gets all or part of its carbon, water, or nutrient supply through symbiotic association with fungi. The term can refer to plants that engage in either of two distinct symbioses with fungi: *Many mycotrophs have a mutualistic association with fungi in any of several forms of mycorrhiza. The majority of plant species are mycotrophic in this sense. Examples include Burmanniaceae. *Some mycotrophs are parasitic upon fungi in an association known as myco-heterotrophy Myco-heterotrophy (from Ancient Greek, Greek μύκης , "fungus", ἕτερος ', "another", "different" and τροφή ', "nutrition") is a symbiosis, symbiotic relationship between certain kinds of plants and fungi, in which the plant gets a ....

Margaret Flockton Award
Margaret Lilian Flockton (29 September 1861 Sussex – 12 August 1953 Sydney), is most commonly recognized as a botanical artist famous for her botanical illustrations of ''"The Forest Flora of New South Wales"'' (some 300 plates), ''"A Critical Revision of the Genus Eucalyptus"'', and the genus ''Opuntia'', all by the botanist and forester, Joseph Henry Maiden.

Plant Litter
Plant litter (also leaf litter, tree litter, soil litter, litterfall or duff) is dead plant material (such as leaves, bark, needles, twigs, and cladodes) that have fallen to the ground. This detritus or dead organic material and its constituent nutrients are added to the top layer of soil, commonly known as the litter layer or O horizon ("O" for "organic"). Litter is an important factor in ecosystem dynamics, as it is indicative of ecological productivity and may be useful in predicting regional nutrient cycling and soil fertility. Characteristics and variability Litterfall is characterized as fresh, undecomposed, and easily recognizable (by species and type) plant debris. This can be anything from leaves, cones, needles, twigs, bark, seeds/nuts, logs, or reproductive organs (e.g. the stamen of flowering plants). Items larger than 2 cm diameter are referred to as coarse litter, while anything smaller is referred to as fine litter or litter. The type of litterfall is ...

Humus
In classical soil science, humus is the dark organic matter in soil that is formed by the decomposition of plant and animal matter. It is a kind of soil organic matter. It is rich in nutrients and retains moisture in the soil. Humus is the Latin word for "earth" or "ground". In agriculture, "humus" sometimes also is used to describe mature or natural compost extracted from a woodland or other spontaneous source for use as a soil conditioner. It is also used to describe a topsoil horizon that contains organic matter (''humus type'', ''humus form'', or ''humus profile''). Humus has many nutrients that improve the health of soil, nitrogen being the most important. The ratio of carbon to nitrogen (C:N) of humus commonly ranges between eight and fifteen with the median being about twelve. It also significantly affects the bulk density of soil. Humus is amorphous and lacks the "cellular cake structure characteristic of plants, micro-organisms or animals". Description The primary ...
