Hainanecio
''Hainanecio'' ( zh, s=海南菊属) is a genus of flowering perennial herb endemic to Hainan Island, China. A single species, ''Hainanecio hainanensis'', has been described from three populations on Hainan Island. It grows in shade in dense, broadleaved evergreen forests at 900–1200 m above sea level. It flowers from July to August and fruits in September to November. The sole species was first described as ''Senecio hainanensis'' by C. C. Chang & Y. C. Tseng (1974) before being transferred to '' Sinosenecio'' by C. Jeffrey & Y. L. Chen (1984). It was believed to be the southernmost-occurring species of ''Sinosenecio'' before being reclassified in 2011 by Y. Liu & Q. E. Yang as its own genus and species. Molecular phylogenetic analysis places ''H. hainanensis'' as an isolated member of the subtribe Senecioninae, being only distantly related to ''Sinosenecio'' species with basic chromosome number 30 or '' Tephroseris'' species with basic chromosome number 24.

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 ...

Hainan
Hainan is an island provinces of China, province and the southernmost province of China. It consists of the eponymous Hainan Island and various smaller islands in the South China Sea under the province's administration. The name literally means "South of the Sea". The province has a land area of , of which Hainan Island is and the rest is over 200 islands scattered across three archipelagos: Zhongsha Islands, Zhongsha, Xisha Islands, Xisha and Nansha Islands, Nansha. It was part of Guangdong from 1950 to 1988, after which it was made a province of its own and was designated as a special economic zones of China, special economic zone by Deng Xiaoping, as part of the Chinese economic reform program. The Han Han Chinese, Chinese population, who compose a majority of the population at 82%, speak a wide variety of languages including Standard Chinese, Hainanese, Hainam Min, Yue Chinese, Cantonese, Hakka Chinese, etc. Indigenous peoples such as the Hlai people, Hlai, a Kra–Dai l ...

Pollen
Pollen is a powdery substance produced by most types of flowers of seed plants for the purpose of sexual reproduction. It consists of pollen grains (highly reduced Gametophyte#Heterospory, microgametophytes), which produce male gametes (sperm cells). Pollen grains have a hard coat made of sporopollenin that protects the gametophytes during the process of their movement from the stamens to the pistil of flowering plants, or from the male Conifer cone, cone to the female cone of gymnosperms. If pollen lands on a compatible pistil or female cone, it Germination, germinates, producing a pollen tube that transfers the sperm to the ovule containing the female gametophyte. Individual pollen grains are small enough to require magnification to see detail. The study of pollen is called palynology and is highly useful in paleoecology, paleontology, archaeology, and Forensic science, forensics. Pollen in plants is used for transferring Ploidy#Haploid and monoploid, haploid male genetic ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of China
The flora of China consists of a diverse range of plant species including over 39,000 vascular plants, 27,000 species of fungi and 3000 species of bryophytes.Wu, Z. Y., P. H. Raven & D. Y. Hong, eds. 2006. Flora of China. Vol. 22 (Poaceae). Science Press, Beijing, and Missouri Botanical Garden Press, St. Louis - http://www.efloras.org/volume_page.aspx?volume_id=2022&flora_id=2 More than 30,000 plant species are native to China, representing nearly one-eighth of the world's total plant species, including thousands found nowhere else on Earth. China's land, extending over 9.6 million km, contains a variety of ecosystems and climates for plants to grow in. Some of the main climates include shores, tropical and subtropical forests, deserts, elevated plateaus and mountains. The events of the continental drift and early Paleozoic Caledonian movement also play a part in creating climatic and geographical diversity resulting in high levels of endemic vascular flora. These landscapes prov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monotypic Asteraceae 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. ...
