Type Specimen
In biology, a type is a particular wikt:en:specimen, specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally associated. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set (mathematics), set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN), the ...

Sobralia Gentryi
''Sobralia'' is a genus of orchids native to Mexico, Central and South America. The plants are more commonly terrestrial, but are also found growing epiphytically, in wet forests from sea level to about 8,800 ft. The genus was named for Dr. Francisco Sobral, a Spanish botanist. The genus is abbreviated Sob in trade journals. Their reed-like stems range in height from about 1 ft (33 cm) (such as in ''Sobralia galeottiana'') to 44 ft. (13.4 m) (in ''Sobralia altissima''). They have typically heavily veined, bilobed, plicate, apical leaves all along the stem. The inflorescences on the apex of the stem carry one or two successive ephemeral flowers with large sepals and petals. The short duration of the flower is caused by a self-digesting enzyme. The lip is entire or lobed and clasps the column at its base. This columns carries eight soft pollinia. These flowers range in color from pure white to yellow, green, pink, purple, red, brown, and even a blue violet. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
