Question: Which species is native to Asia, Corokia or Rhodotypos?

Passages:
Brassica elongata, the elongated mustard or long-stalked rape, is a species of the mustard plant that is native to parts of Central Europe, Eastern Europe, the Balkan Peninsula, the Caucasus, Morocco and parts of Central Asia.  Through plant invasion this species has become naturalized in many other parts of the world.  Some of these naturalized regions include South Africa, North Western Europe, Australia and North America.  Given the wide range of climate and ecological conditions of these regions, "B. elongata" has been able to disrupt the ecosystems of their native plant habitats and has been label as an invasive species in many of its naturalized zones.  In North America, this species is often found as a roadside weed in the southwestern states, particularly in the state of Nevada.  Studies allude that the Cruciferae might have migrated through the Bering land bridge from what is now Central Asia.  Commonly known as the long-stalked rape or as "langtraubiger Kohl " in German, this species is a close cousin to "Brassica napus" (rapeseed) and a secondary genetic relative to "B. oleracea" (kale).  As a close genetic species of the rapeseed, the long-stalked rape has one of the highest counts of accumulated polyunsaturated linoleic and linolenic acid.  Both compounds are heavily used to manufacture vegetable oils.  "Brassica elongata" has the propagative potential of turning into a horticultural product from what is currently a noxious weed. A civet is a small, lithe-bodied, mostly nocturnal mammal native to tropical Asia and Africa, especially the tropical forests.  The term civet applies to over a dozen different mammal species.  Most of the species diversity is found in southeast Asia.  The best-known civet species is the African civet, "Civettictis civetta", which historically has been the main species from which was obtained a musky scent used in perfumery.  The word "civet" may also refer to the distinctive musky scent produced by the animals. Starlings are small to medium-sized passerine birds in the family Sturnidae.  The name "Sturnidae" comes from the Latin word for starling, "sturnus".  Many Asian species, particularly the larger ones, are called mynas, and many African species are known as glossy starlings because of their iridescent plumage.  Starlings are native to Europe, Asia and Africa, as well as northern Australia and the islands of the tropical Pacific.  Several European and Asian species have been introduced to these areas as well as North America, Hawaii and New Zealand, where they generally compete for habitats with native birds and are considered to be invasive species.  The starling species familiar to most people in Europe and North America is the common starling, and throughout much of Asia and the Pacific, the common myna is indeed common. 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. 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. Agrilus planipennis, commonly known as the emerald ash borer, is a green buprestid or jewel beetle native to northeastern Asia that feeds on ash species.  Females lay eggs in bark crevices on ash trees, and larvae feed underneath the bark of ash trees to emerge as adults in one to two years.  In its native range, it is typically found at low densities and does not cause significant damage to trees native to the area.  Outside its native range, it is an invasive species and is highly destructive to ash trees native to northwest Europe and North America.  Prior to being found in North America, very little was known about emerald ash borer in its native range; this has resulted in much of the research on its biology being focused in North America.  Local governments in North America are attempting to control it by monitoring its spread, diversifying tree species, insecticides, and biological control. Rhodotypos scandens, the sole species of the genus Rhodotypos, is a deciduous shrub in the family Rosaceae, closely related to "Kerria" and included in that genus by some botanists.  It is native to China, possibly also Japan. The giant gourami ("Osphronemus goramy") is a species of large gourami native to Southeast Asia, with its occurrence in other locations due to introductions.  They are native to Chao Phraya and Mekong basin in mainland Southeast Asia, and also rivers of Borneo, Java and Sumatra.  This species is commercially important as a food fish and is also farmed.  It can also be found in the aquarium trade.  The species has also been used for weed control, as it can be a voracious herbivore. Flemingia is a genus of flowering plants in the legume family Fabaceae.  It is native to Asia and the species are distributed in Bhutan, Burma, China, India; Indonesia, Laos, Malaysia, Nepal, Pakistan, Papua New Guinea, Philippines, Sri Lanka, Taiwan, Thailand and Vietnam.  The genus was founded in 1812.  The number of known species is ambiguous due to taxonomic problems; and is usually enumerated as more than 30.  Burma and China have the highest record of "Flemingia" species with 16 each, followed by India (with 15 species), Thailand (11 species), Laos (10 species), Vietnam (8 species), Bhutan (1 species) and Nepal (5 species). Cyrtandra is a genus of flowering plants containing about 600 species, with more being discovered often, and is thus the largest genus in the family Gesneriaceae.  These plants are native to Southeast Asia, Australia, and the Pacific Islands, with the centre of diversity in Southeast Asia and the Malesian region.  The genus is common, but many species within it are very rare, localized, endangered endemic plants.  The species can be difficult to identify because they are highly polymorphic and because they readily hybridize with each other.  The plants may be small herbs, vines, shrubs, epiphytes, or trees.  The genus is characterized in part by having two stamens, and most species have white flowers, with a few red-, orange-, yellow- and pink-flowered species known.  Almost all species live in rainforest habitats.
