Question: Which is native to China, Encephalartos or Ginkgo biloba?
Context: "Gingo biloba" (later: "Ginkgo biloba") is a poem written by the German poet Johann Wolfgang von Goethe.  The poem was published in his work "West-östlicher Diwan" "(West-Eastern Divan)", first published in 1819.  Goethe used "Gingo" instead of "Ginkgo" in the first version to avoid the hard sound of the letter "k". Yimaiaceae is a family of extinct plants, in the order Ginkgoales.  It closely related to the "Ginkgo biloba", the only remaining species of Ginkgoales. Ginkgo gardneri is an extinct ginkgo species in the family Ginkgoaceae from the Paleocene of Scotland.  The Ginkgo gardneri is found fossilized in Western Europe.  This species is very closely related to the Ginkgo biloba, the only living species of the genus Ginkgo.  Michael Ward, a scientist, found the fossils in 2017. Ginkgoidae is a subclass of Equisetopsida in the sense used by Mark W. Chase and James L. Reveal in their 2009 article "A phylogenetic classification of the land plants to accompany APG III."  This subclass contains the single extant genus "Ginkgo" under order Ginkgoales, family Ginkgoaceae.  Its only extant species is "Ginkgo biloba", the Maidenhair Tree. The Botanischer Garten Kaiserberg (2 hectares) is a botanical garden located at Schweizer Straße 24, Duisburg, North Rhine-Westphalia, Germany.  The garden was established in 1890 and primarily cultivates native plants, but also includes exotic flora such as "Araucaria", "Ginkgo biloba", "Sequoiadendron".  It is open daily without charge, and should not be confused with the Botanischer Garten Duisburg-Hamborn, another botanical garden in Duisburg. Ginkgoales or Ginkgophyte is a gymnosperm order containing only one extant species: "Ginkgo biloba", the ginkgo tree.  It is monotypic, (the only taxon) within the class Ginkgoopsida, which itself is monotypic within the division Ginkgophyta.  The order includes five families, of which only Ginkgoaceae remains extant. The Ginkgoaceae is a family of gymnosperms which appeared during the Mesozoic Era, of which the only extant representative is "Ginkgo biloba", which is for this reason sometimes regarded as a living fossil.  Formerly, however, there were several other genera, and forests of ginkgo existed.  Because leaves can take such diverse forms within a single species, these are a poor measure of diversity, although differing structures of wood point to the existence of diverse ginkgo forests in ancient times. Encephalartos is a genus of cycad native to Africa.  Several species of "Encephalartos" are commonly referred to as bread trees, bread palms or kaffir bread, since a bread-like starchy food can be prepared from the centre of the stem.  The genus name is derived from the Greek words "en" (within), "kephali" (head), and "artos" (bread), referring to the use of the pith to make food.  They are, in evolutionary terms, some of the most primitive living gymnosperms. Ginkgo is a genus of highly unusual non-flowering plants.  The scientific name is also used as the English name.  The order to which it belongs, Ginkgoales, first appeared in the Permian, 270 million years ago, possibly derived from "seed ferns" of the order Peltaspermales.  The rate of evolution within the genus has been slow, and almost all its species had become extinct by the end of the Pliocene; the exception is the sole living species, "Ginkgo biloba", which is only found in the wild in China, but is cultivated across the world.  The relationships between ginkgos and other groups of plants are not fully resolved. Ginkgo biloba, commonly known as ginkgo or gingko (both pronounced ), also known as the ginkgo tree or the maidenhair tree, is the only living species in the division Ginkgophyta, all others being extinct.  It is found in fossils dating back 270 million years.  Native to China, the tree is widely cultivated and was introduced early to human history.  It has various uses in traditional medicine and as a source of food.  The genus name "Ginkgo" is regarded as a misspelling of the Japanese "gin kyo", "silver apricot".
Answer: Ginkgo biloba
