Information: - North Carolina is a state in the southeastern region of the United States. The state borders South Carolina and Georgia to the south, Tennessee to the west, Virginia to the north, and the Atlantic Ocean to the east. North Carolina is the 28th most extensive and the 9th most populous of the U.S. states. The state is divided into 100 counties. The capital is Raleigh. The most populous municipality is Charlotte, and it is the second largest banking center in the United States after New York City. - Asteraceae or Compositae (commonly referred to as the aster, daisy, composite, or sunflower family) is an exceedingly large and widespread family of flowering plants (Angiospermae). - Tennessee ("Tanasi") is a state located in the southeastern region of the United States. Tennessee is the 36th largest and the 16th most populous of the 50 United States. Tennessee is bordered by Kentucky and Virginia to the north, North Carolina to the east, Georgia, Alabama, and Mississippi to the south, and Arkansas and Missouri to the west. The Appalachian Mountains dominate the eastern part of the state, and the Mississippi River forms the state's western border. Tennessee's capital and second largest city is Nashville, which has a population of 654,610. Memphis is the state's largest city, with a population of 655,770. - Appalachia is a cultural region in the Eastern United States that stretches from the Southern Tier of New York to northern Alabama, Mississippi and Georgia. While the Appalachian Mountains stretch from Belle Isle (Newfoundland and Labrador) in Canada to Cheaha Mountain in Alabama, the cultural region of Appalachia typically refers only to the central and southern portions of the range. As of the 2010 United States Census, the region was home to approximately 25 million people. - A mountain range (also mountain barrier, belt, or system) is a geographic area containing numerous geologically related mountains. A mountain system or system of mountain ranges, sometimes is used to combine several geological features that are geographically (regionally) related. On Earth, most significant mountain ranges are the result of plate tectonics, though mountain ranges are formed by a range of processes, are found on many planetary mass objects in the Solar System and are likely a feature of most terrestrial planets. - The genus Cacalia L. is a "nomen rejiciendum" (rejected name) under the International Code of Nomenclature for algae, fungi, and plants. The type species "C. alpina" L. has been transferred to "Adenostyles alpina" (L.) Bluff & Fingerh., and the former species of "Cacalia" now reside in a few different genera. - The Great Smoky Mountains are a mountain range rising along the TennesseeNorth Carolina border in the southeastern United States. They are a subrange of the Appalachian Mountains, and form part of the Blue Ridge Physiographic Province. The range is sometimes called the Smoky Mountains and the name is commonly shortened to the Smokies. The Great Smokies are best known as the home of the Great Smoky Mountains National Park, which protects most of the range. The park was established in 1934, and, with over 9 million visits per year, it is the most-visited national park in the United States. - Adenostyles is a genus of flowering plants in the sunflower family Asteraceae, and of the tribe Senecioneae. It was described as a genus in 1816. "Adenostyles" occur in the temperate climates of the northern hemisphere, mainly in Europe and Asia Minor. - Senecio is a genus of the daisy family (Asteraceae) that includes ragworts and groundsels. The scientific Latin genus name, "Senecio", means "old man." - The International Code of Nomenclature for algae, fungi, and plants (ICN) is the set of rules and recommendations dealing with the formal botanical names that are given to plants, fungi and a few other groups of organisms, all those "traditionally treated as algae, fungi, or plants". It was formerly called the International Code of Botanical Nomenclature (ICBN); the name was changed at the International Botanical Congress in Melbourne in July 2011 as part of the "Melbourne Code" which replaces the "Vienna Code" of 2005. As with previous codes, it took effect as soon as it was ratified by the congress (on Saturday 23 July 2011), but the documentation of the code in its final form was not finished until some time after the congressional meeting. Preliminary wording of some of the articles with the most significant changes has been published in September 2011. - Rugelia nudicaulis , Rugel 's Indian plantain or Rugels ragwort , is the sole species of the genus Rugelia which blooms in summer , is a wildflower endemic to higher elevations in the Great Smoky Mountains . It is a rare species in Tennessee . It was first placed in the genus Senecio , then moved to Cacalia and finally placed in a genus of its own , Rugelia . Genetic diversity in this plant , assessed using allozymes , is so low that the species may not survive changing environmental conditions . - Great Smoky Mountains National Park is a United States National Park and UNESCO World Heritage Site that straddles the ridgeline of the Great Smoky Mountains, part of the Blue Ridge Mountains, which are a division of the larger Appalachian Mountain chain. The border between Tennessee and North Carolina runs northeast to southwest through the centerline of the park. It is the most visited national park in the United States. On its route from Maine to Georgia, the Appalachian Trail also passes through the center of the park. The park was chartered by the United States Congress in 1934 and officially dedicated by President Franklin Delano Roosevelt in 1940. It encompasses , making it one of the largest protected areas in the eastern United States. The main park entrances are located along U.S. Highway 441 (Newfound Gap Road) at the towns of Gatlinburg, Tennessee, and Cherokee, North Carolina. It was the first national park whose land and other costs were paid for in part with federal funds; previous parks were funded wholly with state money or private funds. Due to the 2016 Great Smoky Mountains wildfires, the Park was under evacuation orders, along with some towns and cities located nearby. What is the relationship between 'rugelia' and 'asteraceae'?
