Question: Are the following plants members of the different families: Nerium and Mitchella?

full_context: Document 1: Mitchella: Mitchella is a genus of flowering plants in the Rubiaceae family. It is found from China to temperate eastern Asia, and from eastern Canada to Guatemala.
Document 2: Plumeria: Plumeria ( ) is a genus of flowering plants in the dogbane family, Apocynaceae. Most species are deciduous shrubs or small trees. The species variously are indigenous to Mexico, Polynesia, Central America, and the Caribbean, and as far south as Brazil, but are grown as cosmopolitan ornamentals in warm regions. Common names for plants in the genus vary widely according to region, variety, and whim, but frangipani or variations on that theme are the most common. Plumeria also is used directly as a common name, especially in horticultural circles.
Document 3: Micromeria: Micromeria is a genus of flowering plants in the mint family, Lamiaceae, widespread across Europe, Asia, Africa, and North America, with a center of diversity in the Mediterranean region and the Canary Islands. It is sometimes placed within the genus "Satureja". The name is derived from the Greek words
Document 4: Moringa oleifera: Moringa oleifera is the most widely cultivated species of the genus "Moringa", which is the only genus in the family Moringaceae. English common names include: moringa, drumstick tree (from the appearance of the long, slender, triangular seed-pods), horseradish tree (from the taste of the roots, which resembles horseradish), ben oil tree, or benzoil tree (from the oil which is derived from the seeds). It is a fast-growing, drought-resistant tree, native to the southern foothills of the Himalayas in northwestern India, and widely cultivated in tropical and subtropical areas where its young seed pods and leaves are used as vegetables. It can also be used for water purification and hand washing, and is sometimes used in herbal medicine.
Document 5: Mitchella repens: Mitchella repens (partridge berry, or squaw vine) is the best known plant in the genus "Mitchella".
Document 6: Nerium: Nerium oleander is a shrub or small tree in the dogbane family Apocynaceae, toxic in all its parts. It is the only species currently classified in the genus Nerium. It is most commonly known as nerium or oleander, from its superficial resemblance to the unrelated olive "Olea". It is so widely cultivated that no precise region of origin has been identified, though southwest Asia has been suggested. The ancient city of Volubilis in Morocco may have taken its name from the Berber name "oualilt" for the flower. Oleander is one of the most poisonous commonly grown garden plants.
Document 7: 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 8: Mimulus: Mimulus is a plant genus in the family Phrymaceae, which was traditionally placed in family Scrophulariaceae. The genus now contains only seven species, two native to eastern North America and the other five native to Asia, Australia, Africa, or Madagascar. In the past, about 150 species were placed in this genus, most of which have since been assigned to other genera, the majority to genus "Erythranthe". "Mimulus
Document 9: Oleaceae: The Oleaceae are a family of flowering plants in the order Lamiales. It presently comprises 26 genera, one of which is recently extinct. The 25 extant genera include "Cartrema", which was resurrected in 2012. The number of species in the Oleaceae is variously estimated in a wide range around 700. The Oleaceae consist of shrubs, trees, and a few lianas. The flowers are often numerous and highly odoriferous. The family has a subcosmopolitan distribution, ranging from the subarctic to the southernmost parts of Africa, Australia, and South America. Notable members of the Oleaceae include olive, ash, jasmine, and several popular ornamental plants including privet, forsythia, fringetrees, and lilac.
Document 10: Thevetia: Thevetia is a genus of flowering plants in the dogbane family, Apocynaceae, first described for modern science as a genus in 1758. It is native to Mexico, Central America, South America, and Cuba. The taxonomy of the genus is controversial, with some authors including "Cascabela" within "Thevetia", while others accept the two genera as separate.
Document 11: Michauxia: Michauxia is a genus of plants in the Campanulaceae. It contains 7 known species native to southwestern Asia.
Document 12: Gomphocarpus fruticosus: Gomphocarpus fruticosus (syn. "Asclepias fruticosa") is a species of milkweed native to South Africa. It is also common in New Zealand where it is the main host of the monarch butterfly. The plant's tissues contain sufficient cardenolides that consumption of significant quantities of the plant's leaves, stems, or fruit may lead to death in livestock and humans.
Document 13: Manettia: Manettia is a genus of flowering plants in the family Rubiaceae. There are between 80 and 123 species. They are distributed in the West Indies, Mexico, and Central and South America. Most are vines. The genus was named after Saverio Manetti.
Document 14: Scadoxus multiflorus: Scadoxus multiflorus (formerly "Haemanthus multiflorus") is a bulbous plant native to most of sub-Saharan Africa from Senegal to Somalia to South Africa. It is also native to Arabian Peninsula (Saudi Arabia, Yemen, Oman) and to the Seychelles. It is naturalized in Mexico and in the Chagos Archipelago. It is grown as an ornamental plant for its brilliantly coloured flowers, either in containers or in the ground in where the climate is suitable. There are three recognized subspecies. Strongly toxic like other "Scadoxus" species, it has been used as a component of arrow poisons and fishing poisons, as well as in traditional medicine. Common names, some of which are used for other species, include blood lily, ball lily, blood flower, Katherine-wheel, oxtongue lily, poison root and powderpuff lily.
Document 15: Datura: Datura is a genus of nine species of poisonous vespertine flowering plants belonging to the family Solanaceae. They are commonly known as daturas, but also known as devil's trumpets, not to be confused with angel's trumpets, its closely related genus "Brugmansia". They are also sometimes called moonflowers, jimsonweed, devil's weed, hell's bells, thorn-apple, and many more. Its precise and natural distribution is uncertain, owing to its extensive cultivation and naturalization throughout the temperate and tropical regions of the globe. Its distribution within the Americas and North Africa, however, is most likely restricted to the United States and Mexico and Southern Canada in North America, and Tunisia in Africa, where the highest species diversity occurs.
