Sinadoxa
''Sinadoxa corydalifolia'' is the only species in the monotypic plant genus ''Sinadoxa'', in the family Adoxaceae. It is endemic to the Hengduan Mountains of the Tibetan Plateau in China. It is a perennial herb growing from a fibrous root system with rhizomes. It produces one to four upright, green stems up to 25 centimeters tall and just a few millimeters wide. The basal leaves are pinnate, made up of leaflets which may be lobed or subdivided. There is usually one opposite pair of leaves higher on the stem, each with three leaflets. The inflorescence In botany, an inflorescence is a group or cluster of flowers arranged on a plant's Plant stem, stem that is composed of a main branch or a system of branches. An inflorescence is categorized on the basis of the arrangement of flowers on a mai ... is a spike with interrupted clusters of 3 to 5 small, yellow-green to yellow-brown flowers. Flowering occurs in June and July. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adoxaceae
Adoxaceae, commonly known as moschatel family, is a small family of flowering plants in the order Dipsacales, now consisting of five genera and about 150–200 species. They are characterised by opposite toothed leaves, small five- or, more rarely, four-petalled flowers in cymose inflorescences, and the fruit being a drupe. They are thus similar to many Cornaceae. In older classifications, this entire family was part of Caprifoliaceae, the honeysuckle family. ''Adoxa'' (moschatel) was the first plant to be moved to this new group. Much later, the genera '' Sambucus'' (elders) and '' Viburnum'' were added after careful morphological analysis and biochemical tests by the Angiosperm Phylogeny Group. An additional monotypic genus '' Sinadoxa'' has been added based on molecular comparison with ''Adoxa''. Recent sources, including the Angiosperm Phylogeny Website, treat this family as Viburnaceae Raf., ''nom. cons.'' ''Adoxa'' is a small perennial herbaceous plant, flowering ea ...

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 ...

Endemism
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Hengduan Mountains
The Hengduan Mountains () are a group of mountain ranges in southwest China, southwest China that connect the southeast portions of the Tibetan Plateau with the Yunnan–Guizhou Plateau. The Hengduan Mountains are primarily large north-south mountain ranges that effectively separate lowlands in northern Myanmar from the lowlands of the Sichuan Basin. These ranges are characterized by significant vertical relief originating from the Indian subcontinent's collision with the Eurasian Plate, and further carved out by the major rivers draining the eastern Tibetan Plateau. These rivers, the Yangtze, Mekong, and Salween, are recognized today as the Three Parallel Rivers of Yunnan Protected Areas, Three Parallel Rivers UNESCO World Heritage Site. The Hengduan Mountains cover much of western present-day Sichuan province as well as the northwestern portions of Yunnan, the easternmost section of the Tibet Autonomous Region, and touching upon parts of southern Qinghai.

Rhizome
In botany and dendrology, a rhizome ( ) is a modified subterranean plant stem that sends out roots and Shoot (botany), shoots from its Node (botany), nodes. Rhizomes are also called creeping rootstalks or just rootstalks. Rhizomes develop from axillary buds and grow horizontally. The rhizome also retains the ability to allow new shoots to grow upwards. A rhizome is the main stem of the plant that runs typically underground and horizontally to the soil surface. Rhizomes have nodes and internodes and auxiliary buds. Roots do not have nodes and internodes and have a root cap terminating their ends. In general, rhizomes have short internodes, send out roots from the bottom of the nodes, and generate new upward-growing shoots from the top of the nodes. A stolon is similar to a rhizome, but stolon sprouts from an existing stem having long internodes and generating new shoots at the ends, they are often also called runners such as in the strawberry plant. A stem tuber is a thickene ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inflorescence
In botany, an inflorescence is a group or cluster of flowers arranged on a plant's Plant stem, stem that is composed of a main branch or a system of branches. An inflorescence is categorized on the basis of the arrangement of flowers on a main axis (Peduncle (botany), peduncle) and by the timing of its flowering (determinate and indeterminate). Morphology (biology), Morphologically, an inflorescence is the modified part of the Shoot (botany), shoot of spermatophyte, seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internode (botany), internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. General characteristics Inflorescences are described by many different charact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dipsacales Genera
The Dipsacales are an order (biology), order of flowering plants, included within the asterid group of dicotyledons. In the APG III system of 2009, the order includes only two families, Adoxaceae and a broadly defined Caprifoliaceae. Some well-known members of the Dipsacales order are honeysuckle, Sambucus, elder, viburnum, and Valerian (herb), valerian. Under the Cronquist system, the order included Adoxaceae, Caprifoliaceae sensu stricto, Dipsacaceae, and Valerianaceae. Under the 2003 APG II system, the circumscription of the order was much the same but the system allowed either a broadly circumscribed Caprifoliaceae including the families Diervillaceae, Dipsacaceae, Linnaeaceae, Morinaceae, and Valerianaceae, or these families being kept separate. The APG III system only uses the broadly circumscribed Caprifoliceae. The Dipsacales appear to be most closely related to the Paracryphiales. References *Bell, C. D., E. J. Edwards, S. T. Kim, & M.
