Question: Which is native to Africa, Cylindropuntia or Encephalartos?
Context: Cylindropuntia acanthocarpa, commonly referred to as buckhorn cholla, is a cholla native to the Mojave, Sonoran, and Colorado Deserts of North America.  Along with Cylindropuntia bigelovii (the "teddy bear" cholla), it is the most common cholla found in these deserts. Encephalartos cycadifolius is a species of cycad that is native to the Winterberg mountains to the north of Bedford in the Eastern Cape province, South Africa.  It is found at elevations from 1,200 to 1,800 meters. Encephalartos senticosus is a species of cycad in the family Zamiaceae native to the Lebombo Mountains of Mozambique, Swaziland and the KwaZulu-Natal province of South Africa.  Prior to its description in 1996, "Encephalartos senticosus" had been confused with the closely related and sympatric "Encephalartos lebomboensis".  Both species are commonly known as the Lebombo cycad. 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. Encephalartos brevifoliolatus, the escarpment cycad, is a cycad in the African genus "Encephalartos".  It is extinct in the wild.  The escarpment cycad is an African plant that was found in South Africa in short grasslands in the very open "Protea" savanna.  These plants are used to growing on large cliffs. Encephalartos woodii, Wood's cycad, is a rare cycad in the genus "Encephalartos", and is endemic to the oNgoye Forest of KwaZulu-Natal, South Africa.  It is one of the rarest plants in the world, being extinct in the wild with all specimens being clones of the type.  The specific and common name both honour John Medley Wood, curator of the Durban Botanic Garden and director of the Natal Government Herbarium of South Africa, who discovered the plant in 1895. Cylindropuntia is a genus of cacti (family Cactaceae), containing the cholla, native to northern Mexico and the Southwestern United States.  They are known for their barbed spines that tenaciously attach to skin, fur, and clothing. Encephalartos turneri is a species of cycad that is native to Mozambique.  The Encephalartos turneri was discovered by Ian Turner in Nampula, Mazambique. Encephalartos lebomboensis is a species of cycad in the family Zamiaceae.  Native to the Lebombo Mountains of South Africa, the species was first described in 1949 by the South African botanist Inez Verdoorn.  It is commonly known as the Lebombo cycad, although the name is also used for "Encephalartos senticosus" which also occurs in the same locality. Encephalartos horridus, the Eastern Cape blue cycad, is a small, low-growing cycad up to 0.9 m high and 0.9 m wide.  It is a native of Eastern Cape Province, South Africa, and found in arid shrublands, most commonly on ridges and slopes with shallow soils.  The species is particularly known for its distinctly blue-gray leaves, although the degree of coloration can vary significantly.  The species name "horridus" is Latin for 'bristly', after the plant's stiff, spiny leaflets.
Answer: Encephalartos
