Information: - 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. - Vienna is the capital and largest city of Austria and one of the nine states of Austria. Vienna is Austria's primary city, with a population of about 1.8million (2.6million within the metropolitan area, nearly one third of Austria's population), and its cultural, economic, and political centre. It is the 7th-largest city by population within city limits in the European Union. Until the beginning of the 20th century, it was the largest German-speaking city in the world, and before the splitting of the Austro-Hungarian Empire in World War I, the city had 2 million inhabitants. Today, it has the second largest number of German speakers after Berlin. Vienna is host to many major international organizations, including the United Nations and OPEC. The city is located in the eastern part of Austria and is close to the borders of the Czech Republic, Slovakia, and Hungary. These regions work together in a European Centrope border region. Along with nearby Bratislava, Vienna forms a metropolitan region with 3million inhabitants. In 2001, the city centre was designated a UNESCO World Heritage Site. - Melbourne is the capital and most populous city of the Australian state of Victoria, and the second-most populous city in Australia. The name "Melbourne" refers to an urban agglomeration spanning which comprises the broader metropolitan area, as well as being the common name for its city centre. The metropolis is located on the large natural bay of Port Phillip and expands into the hinterlands towards the Dandenong and Macedon mountain ranges, Mornington Peninsula and Yarra Valley. Melbourne consists of 31 municipalities. It has a population of 4,529,500 , and its inhabitants are called Melburnians. - Senecioneae is the largest tribe of the Asteraceae, or the sunflower family, comprising approximately 150 genera and 3,000 species. Almost one-third of the species in this tribe are placed in the genus "Senecio". Its members exhibit probably the widest possible range of form to be found anywhere in the entire plant kingdom and include annuals, minute creeping alpines, perennial herbs, shrubs, climbers, succulents, trees and semi-aquatic plants. - 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. - 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 code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae (Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia)." - 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). What entity does 'cacalia' has the relation 'parent taxon' with?
The answer to this question is:
asteraceae
