Question: Are Duvalia and Sprekelia both types of plants?

full_context: Document 1: Griffineae: The tribe Griffineae (in the family Amaryllidaceae, subfamily Amaryllidoideae) includes 2 genera with 22 species from South America which are actually endemic to Brazil. A typical character of the representatives of the tribe are the flowers - They are with blue or lilac color collected into an umbel. Only the members of this tribe and the genus "Lycoris" are able to form flowers with such color in the whole Amaryllidaceae family. The plants in this group are typical perennial flowers which are producing bulbs. The leaves are green, with elliptical form in the most of the cases but in some members as in "Worsleya" they are sword-shaped.
Document 2: Eupatorieae: Eupatorieae is a tribe of over 2000 species of plants in the aster family. Most of the species are native to tropical, subtropical, and warm temperate areas of the Americas, but some are found elsewhere. Well-known members are "Stevia rebaudiana" (used as a sugar substitute), a number of medicinal plants ("Eupatorium"), and a variety of late summer to autumn blooming garden flowers, including "Ageratum" (flossflower) and "Conoclinium" (mistflower).
Document 3: Spathiphyllum: Spathiphyllum is a genus of about 40 species of monocotyledonous flowering plants in the family Araceae, native to tropical regions of the Americas and southeastern Asia. Certain species of "Spathiphyllum" are commonly known as Spath or peace lilies.
Document 4: Amaryllis: Amaryllis ( ) is the only genus in the subtribe Amaryllidinae (tribe Amaryllideae). It is a small genus of flowering bulbs, with two species. The better known of the two, "Amaryllis belladonna", is a native of the Western Cape region of South Africa, particularly the rocky southwest area between the Olifants River Valley to Knysna. For many years there was confusion among botanists over the generic names "Amaryllis" and "Hippeastrum", one result of which is that the common name "amaryllis" is mainly used for cultivars of the genus "Hippeastrum", widely sold in the winter months for their ability to bloom indoors. Plants of the genus "Amaryllis" are known as belladonna lily, Jersey lily, naked lady, amarillo, Easter lily in Southern Australia or, in South Africa, March lily due to its propensity to flower around March. This is one of numerous genera with the common name "lily" due to their flower shape and growth habit. However, they are only distantly related to the true lily, "Lilium".
Document 5: Duvalia: Duvalia is a succulent plant genus in the tribe Stapeliae, milkweed subfamily Asclepiadoideae, in the family Apocynaceae (dogbane).
Document 6: Dischidia: Dischidia is a genus of plants in the Milkweed family, Apocynaceae. They are epiphytes native to tropical areas of China, India and most areas of Indo-China. "Dischidia" are closely aligned with the sister genus "Hoya". Unlike "Hoya", the genus "Dischidia" is poorly known and has not been studied as closely.
Document 7: Tigridia: Tigridia , the peacock flowers, tiger-flowers or shell flowers, is a genus of bulbous or cormous plants, belonging to the family Iridaceae. They have large showy flowers and one species, "Tigridia pavonia", is often cultivated for this. The approximately thirty five species in this family grow in the Western Hemisphere, from Mexico to Chile. The tigridia flower is short lived, each often blooming for only one day, but often several flowers will bloom from the same stalk. Usually they are dormant during the winter dry-season. Its roots are edible and were eaten by the Aztecs of Mexico who called it "cacomitl" and its flower "ocēlōxōchitl" "Jaguar flower". The genus name means "tiger-like" and alludes to the coloration and spotting of the flowers of the type species "Tigridia pavonia".
Document 8: 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.
Document 9: 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 10: Sphaeralcea: Sphaeralcea is a genus of flowering plants in the mallow family (Malvaceae). There are about 40-60 species, including annuals, perennials, and shrubs. Most originate in the drier regions of North America, with some known from South America. They are commonly known as globemallows, globe mallows, or falsemallows. The name of the genus is derived from the Greek words σφαῖρα ("sphaira"), meaning "sphere," and αλκεα ("alkea"), meaning "mallow."
Document 11: Quaqua: The genus Quaqua falls within the tribe of plants known collectively as stapeliads. All stapeliads, including "Quaqua", are old world stem succulents.
Document 12: Stapeliae: The genera of plants within the tribe Stapeliae are all to varying degrees stem succulents. Many of the species resemble cacti, though are not closely related, as an example of convergent evolution. The stems are often angular, mostly four-angled in cross-section, but in some species there are six or more, with some species of "Hoodia" having more than thirty angles. In size they vary from less than 2.5 cm/1" in length to over 2 m/6" tall. The leaves are in most species reduced to rudiments, sometimes hardened and thorn-like, arranged on bumps or tubercles on the angles. Some species, however, still have recognisable leaves, most notably the Indian species "Frerea indica", and some members of "Tridentea". Stapeliads are most abundant in warm, dry climates. In Africa, there are two separate regions where Stapeliads have most diversified: northeast Africa, and Southern Africa. Several species are endemic to the small island of Socotra off the Horn of Africa. The Arabian Peninsula, and most specifically the country of Yemen, contain another concentration of species. Several more are found in the drier parts of Pakistan, Afghanistan, India, Nepal, and Myanmar. A single species, "Caralluma europea" is found in Europe, in the very southern part of the Iberian peninsula. Stapeliads are often regarded as a climax group within the family because of their often structurally complex flowers. Certain aspects of these reproductive parts mirror the pollination systems in the Orchid family and represent a case of parallel evolution though both groups are quite unrelated and have developed similar, though not identical means to achieve the ultimate goal of pollination and therefore reproduction. Most stapeliads use flies as pollinators, that are attracted to odours resembling dung or rotting meat, emanating from the flowers. Many of the flowers also bear some physical resemblance to rotting animal carcasses, leading to their popular name of Carrion Flowers. However, not all stapeliads smell bad, or attract flies. Some species use beetles, bees, wasps, butterflies or moths as pollinators. Stapeliad flowers range in size from mere millimetres in species of "Echidnopsis" and "Pseudolithos" to those of "Stapelia gigantea" that can reach 40 cm/16" in diameter, and are some the largest of flowers to be found on any species of succulent.
Document 13: Delairea: Delairea is a plant genus within the family Asteraceae. It is classified within tribe Senecioneae. It contains only one species, Delairea odorata, which was previously included in the genus Senecio as "Senecio mikanioides", and is known as Cape ivy in some parts of the world and German ivy in others.
Document 14: Sprekelia: Sprekelia is a genus of Mesoamerican plants in the Amaryllis family, subfamily Amaryllidoideae. "Sprekelia" plants are sometimes called Aztec lilies or Jacobean lilies although they are not true lilies.
Document 15: Zantedeschia: Zantedeschia is a genus of 8 species of herbaceous, perennial, flowering plants in the family Araceae, native to southern Africa from South Africa north to Malawi. The genus has been introduced on all continents except Antarctica. Common names include arum lily for "Z. aethiopica" and calla and calla lily for "Z. elliottiana" and "Z. rehmannii", although members of the genus are neither true lilies of Liliaceae, true "Arums", or true "Callas" (related genera in Araceae). They are also often confused with "Anthurium". The colourful flowers and leaves of both species and cultivars are greatly valued and commonly grown as ornamental plants.
