Parmelia Semansiana
''Punctelia graminicola'' is a species of foliose (leafy) lichen in the family Parmeliaceae. It grows on rocks, and, less frequently, on bark in North America, South America, and East Africa. It has a blue-grey thallus measuring up to about , covered with tiny pores called pseudocyphellae. Sometimes the lichen forms small lobes that project out from the surface. Fruiting bodies are uncommon in this species; if present, they resemble small cups with a brown internal disc measuring in diameter. A lookalike species, '' Punctelia hypoleucites'', is not readily distinguishable from ''Punctelia graminicola'' by appearance or habitat alone; these species can only be reliably differentiated by examining the length of their conidia (asexual spores). First described in 1942 from specimens collected in New Mexico by Brother Arsène Brouard, the type specimen, stored in Dunkirk, was destroyed during World War II. After that, the name was relegated to synonymy with ''Punctelia subrudec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arkansas
Arkansas ( ) is a landlocked state in the South Central United States. It is bordered by Missouri to the north, Tennessee and Mississippi to the east, Louisiana to the south, and Texas and Oklahoma to the west.

Type (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. 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 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 scientific name of every taxon is almost al ...

Las Vegas, New Mexico
Las Vegas is a city in and the county seat of San Miguel County, New Mexico, United States. Once two separate municipalities (one a city and the other a town), both were named Las Vegas—West Las Vegas ("Old Town") and East Las Vegas ("New Town"); they are separated by the Gallinas River and retain distinct characters and separate, rival school districts. The population was 13,166 at the 2020 census. Las Vegas is located south of Raton, east of Santa Fe, northeast of Albuquerque, south of Colorado Springs, Colorado, and south of Denver. History Las Vegas was established in 1835 after a group of settlers received a land grant from the Mexican government. The town was laid out in the traditional Spanish Colonial style, with a central plaza surrounded by buildings which could serve as fortifications in case of attack. Las Vegas soon prospered as a stop on the Santa Fe Trail. During the Mexican–American War in 1846, Stephen W. Kearny delivered an address at the Plaza ...
