Information:  - China, officially the People's Republic of China (PRC), is a unitary sovereign state in East Asia. With a population of over 1.381 billion, it is the world's most populous country. The state is governed by the Communist Party of China, and its capital is Beijing. It exercises jurisdiction over 22 provinces, five autonomous regions, four direct-controlled municipalities (Beijing, Tianjin, Shanghai, and Chongqing), and two mostly self-governing special administrative regions (Hong Kong and Macau), and claims sovereignty over Taiwan. The country's major urban areas include Shanghai, Guangzhou, Beijing, Chongqing, Shenzhen, Tianjin and Hong Kong. China is a great power and a major regional power within Asia, and has been characterized as a potential superpower.  - × Christieara , abbreviated Chtra . in the horticultural trade , is an intergeneric hybrid between the orchid genera Aerides , Ascocentrum and Vanda ( Aer . x Asctm . x V. ) .  - The Vandeae is a large monophyletic tribe within the family of orchids.  - A raceme (or ) is an unbranched, indeterminate type of inflorescence bearing "pedicellate" flowersflowers having short floral stalks called pedicelsalong its axis. In botany, an "axis" means a shoot, in this case one bearing the flowers. In indeterminate inflorescence-like racemes, the oldest flowers are borne towards the base and new flowers are produced as the shoot grows, with no predetermined growth limit. A plant that flowers on a showy raceme may have this reflected in its scientific name, e.g. "Cimicifuga racemosa". A compound raceme, also called a panicle, has a branching main axis. Examples of racemes occur on mustard (genus "Brassica") and radish (genus "Raphanus") plants.  - Vanda is a genus in the orchid family (Orchidaceae), which although not massive (about 80 species), is one of the genera more commonly found in the marketplace. This genus and its allies are considered to be among the most specifically adapted of all orchids within the Orchidaceae. The genus is highly prized in horticulture for its showy, fragrant, long-lasting, and intensely colorful flowers. "Vanda" species are widespread across East Asia, Southeast Asia, and New Guinea, with a few species extending into Queensland and some of the islands of the western Pacific. The genus is sometimes abbreviated as" V." in the floral trade. Systematic. In a recent molecular study of the genus "Vanda" , several Genera including the former Genus "Ascosentrum", "Neofinitea" and "Euanthe" were believed as a synonym of "Vanda",  - An epiphyte is a plant that grows harmlessly upon another plant (such as a tree) and derives its moisture and nutrients from the air, rain, and sometimes from debris accumulating around it. Epiphytes differ from parasites in that epiphytes grow on other plants for physical support and do not necessarily negatively affect the host. An epiphytic organism that is not a plant is called an epibiont. Epiphytes are usually found in the temperate zone (e.g., many mosses, liverworts, lichens, and algae) or in the tropics (e.g., many ferns, cacti, orchids, and bromeliads). Epiphyte species make good houseplants due to their minimal water and soil requirements. Epiphytes provide a rich and diverse habitat for other organisms including animals, fungi, bacteria, and myxomycetes.  - Queensland (abbreviated as QLD) is the second-largest and third-most-populous state in the Commonwealth of Australia. Situated in the north-east of the country, it is bordered by the Northern Territory, South Australia and New South Wales to the west, south-west and south respectively. To the east, Queensland is bordered by the Coral Sea and Pacific Ocean. Queensland has a population of 4,750,500, concentrated along the coast and particularly in the state's South East. The state is the world's sixth largest sub-national entity, with an area of 1,852,642 km. The capital and largest city in the state is Brisbane, Australia's third largest city. Often referred to as the "Sunshine State", Queensland is home to 10 of Australia's 30 largest cities and is the nation's third largest economy. Tourism in the state, fuelled largely by its warm tropical climate, is a major industry.  - The Orchidaceae are a diverse and widespread family of flowering plants, with blooms that are often colourful and often fragrant, commonly known as the orchid family.  - In plant systematics Epidendroideae is a subfamily of the orchid family, Orchidaceae. Epidendroideae is larger than all the other orchid subfamilies together, comprising more than 15,000 species in 576 genera. Most Epidendroid orchids are tropical epiphytes, typically with pseudobulbs. There are, however, some terrestrials such as "Epipactis" and even a few myco-heterotrophs, which are parasitic upon mycorrhizal fungi.  - Aerides, known commonly as cat's-tail orchids and fox brush orchids, is a genus belonging to the orchid family (Orchidaceae) (subfamily Epidendroideae, tribe Vandeae, subtribe Aeridinae). It is a group of tropical epiphyte orchids that grow mainly in the warm lowlands of tropical Asia from India to southern China to New Guinea. They are valued in horticulture for their racemes of showy, fragrant, colorful flowers.  - India, officially the Republic of India ("Bhrat Gaarjya"), is a country in South Asia. It is the seventh-largest country by area, the second-most populous country (with over 1.2 billion people), and the most populous democracy in the world. It is bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast. It shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the northeast; and Myanmar (Burma) and Bangladesh to the east. In the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives. India's Andaman and Nicobar Islands share a maritime border with Thailand and Indonesia. Its capital is New Delhi; other metropolises include Mumbai, Kolkata, Chennai, Bangalore, Hyderabad and Ahmedabad.  - A flower, sometimes known as a bloom or blossom, is the reproductive structure found in plants that are floral (plants of the division Magnoliophyta, also called angiosperms). The biological function of a flower is to effect reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) or allow selfing (fusion of sperm and egg from the same flower). Some flowers produce diaspores without fertilization (parthenocarpy). Flowers contain sporangia and are the site where gametophytes develop. Many flowers have evolved to be attractive to animals, so as to cause them to be vectors for the transfer of pollen. After fertilization, the ovary of the flower develops into fruit containing seeds.  - East Asia is the eastern subregion of the Asian continent, which can be defined in either geographical or ethno-cultural terms. Geographically and geopolitically, it includes China, Hong Kong, and Macao; Mongolia and Taiwan; North and South Korea; and Japan; it covers about , or about 28% of the Asian continent, about twice the area of Europe.  - In the botanical classification of plants, Aeridinae (formerly Sarcanthinae) is a subtribe of the Tribe Vandeae (Family Orchidaceae) whose representatives all have a monopodial growth habit and do not possess pseudobulbs.     After reading the paragraphs above, we are interested in knowing the entity with which 'christieara' exhibits the relationship of 'parent taxon'. Find the answer from the choices below.  Choices: - aerides  - aeridinae  - area  - areas  - axis  - brassica  - cimicifuga  - epidendroideae  - ferns  - fungi  - magnoliophyta  - orchidaceae  - plant  - raphanus  - sarcanthinae  - vanda  - vandeae
