Question: Which is a genus, Dill or Koelreuteria? 

full_context: Document 1: Dill oil: Dill oil is an essential oil extracted from the seeds or leaves/stems (dillweed) of the Dill plant. It can be used with water to create "dill water".

Document 2: Petroselinum: Petroselinum (parsley) is a genus of two species of flowering plants in the family Apiaceae, native to western and southern Europe and northern Africa. They are bright green hairless biennial herbaceous plants, rarely annual plants. In the first year, they form a rosette of pinnate to tripinnate leaves and a tap root used as a food store over the winter. In the second year they grow a flowering stem up to 1 m tall with sparser leaves and umbels of white or pinkish to yellowish-green flowers.
Document 3: Perilla frutescens: Perilla frutescens, commonly called perilla or Korean perilla, is a species of "Perilla" in the mint family Lamiaceae. It is an annual plant native to Southeast Asia and Indian highlands, and grown in the Korean peninsula, Southern China and India. Known as "deulkkae" (들깨 ) in Korean, the plant was introduced into Korea before the Unified Silla era, when it started to be widely cultivated.
Document 4: Corokia: Corokia is a genus in the Argophyllaceae family comprising about ten species native to New Zealand and one native to Australia. "Corokia" species are shrubs or small trees with zigzagging (divaricating) branches. In fact, "Corokia cotoneaster" is commonly known as "wire-netting bush". The stems of the shrubs are dark when mature, covered with downy or silky hairs (tomentum) when young. In spring, they produce clusters of small, star shaped yellow blossoms. Berries are red or yellow. The shrubs prefer forests and rocky areas, sun or light shade, reasonably well drained soil, and moderate watering.
Document 5: Perilla: Perilla is a genus consisting of one major Asiatic crop species "P. frutescens" and a few recognized wild species in nature, belonging to the mint family, Lamiaceae. It encompasses several distinct varieties of Asian herb, seed, and vegetable crop, including "P. frutescens" (deulkkae) and "P. frutescens" var. "crispa" (shiso). The genus name "Perilla" is also a frequently employed common name ("perilla"), applicable to all varieties. Perilla varieties are cross-fertile and intra-specific hybridization occurs naturally. Some varieties are considered invasive.
Document 6: Stewartia: Stewartia (sometimes spelled Stuartia) is a genus of 8-20 species of flowering plants in the family Theaceae, related to "Camellia". Most of the species are native to eastern Asia in China, Japan, Korea, Laos, Myanmar, Thailand, and Vietnam, with two ("S. malacodendron, S. ovata") in southeast North America, from Virginia and Kentucky south to Florida and Louisiana.
Document 7: Dill: Dill ("Anethum graveolens") is an annual herb in the celery family Apiaceae. It is the only species in the genus "Anethum". Dill is widely grown in Eurasia where its leaves and seeds are used as a herb or spice for flavouring food.
Document 8: Paulownia: Paulownia is a genus of six to 17 species (depending on taxonomic authority) of flowering plants in the family Paulowniaceae, related to and sometimes included in the Scrophulariaceae. They are present in much of China, south to northern Laos and Vietnam and are long cultivated elsewhere in eastern Asia, notably in Japan and Korea. They are deciduous trees 12 – tall, with large, heart-shaped leaves 15–40 cm across, arranged in opposite pairs on the stem. The flowers are produced in early spring on panicles 10–30 cm long, with a tubular purple corolla resembling a foxglove flower. The fruit is a dry capsule, containing thousands of minute seeds.

There are eight species, with "Sophora microphylla" and "S. tetraptera" being the most recognised as large trees. Their natural habitat is beside streams and on the edges of forest, in lowland or mountain open areas. Kōwhai trees grow throughout the country and are a common feature in New Zealand gardens. Outside of New Zealand, kōwhai tend to be restricted to mild temperate maritime climates.
Document 11: Apiaceae: Apiaceae or Umbelliferae, is a family of mostly aromatic flowering plants named after the type genus "Apium" and commonly known as the celery, carrot or parsley family. It is the 16th-largest family of flowering plants, with more than 3,700 species in 434 genera including such well-known and economically important plants such as angelica, anise, asafoetida, caraway, carrot, celery, chervil, coriander, cumin, dill, fennel, hemlock, lovage, cow parsley, parsley, parsnip, sea holly, giant hogweed and silphium (a plant whose identity is unclear and which may be extinct).
Document 12: Kaempferia: Kaempferia is a genus of plants in the ginger family. It is native to China, India, and Southeast Asia (Thailand, Malaysia, Indonesia, Philippines, etc.).
Document 13: Cassia fistula: Cassia fistula, known as the golden rain tree, canafistula and by other names, is a flowering plant in the family Fabaceae. The species is native to the Indian subcontinent and adjacent regions of Southeast Asia. It ranges from southern Pakistan eastward throughout India to Myanmar and Thailand and south to Sri Lanka. It is the state flower of Kerala in India and of immense importance amongst the Malayali population. It is a popular ornamental plant and is also used in herbal medicine. In ancient Tamil literature, it is called கொன்றை (kondrai) and is closely associated with the Mullai (forest) region of Sangam landscape. It is the national tree of Thailand, and its flower is Thailand's national flower.
Document 14: Chervil: Chervil ( ; Anthriscus cerefolium), sometimes called garden chervil to distinguish it from similar plants also called chervil, or French parsley, is a delicate annual herb related to parsley. It is commonly used to season mild-flavoured dishes and is a constituent of the French herb mixture fines herbes.
Document 15: Colocasia: Colocasia is a genus of flowering plants in the family Araceae, native to southeastern Asia and the Indian subcontinent. Some species are widely cultivated and naturalized in other tropical and subtropical regions. Common names include tarul, karkala ko ganu, elephant-ear, taro, cocoyam, dasheen, chembu, champadhumpa, shavige gadde, and eddoe. Elephant-ear and cocoyam are also used for some other large-leaved genera in the Araceae, notably "Xanthosoma" and "Caladium". The generic name is derived from the ancient Greek word "kolokasion", which in the Greek botanist Dioscorides (1st century AD) meant the edible roots of both "Colocasia esculenta" and "Nelumbo nucifera". It is thought that the edible roots of "Colocasia esculenta" have been cultivated in Asia for more than ten thousand years. The species "Colocasia esculenta" is an invasive species in wetlands along the American Gulf coast, where it threatens to displace native wetland plants.
