Question: Are Argyranthemum and Orontium in the same family?

full_context: Document 1: Orontium aquaticum: Orontium aquaticum , sometimes called golden-club, floating arum, never-wets or tawkin, is a species of flowering plants in the Araceae family. It is the single living species in the genus "Orontium", which also contains several extinct species described from fossils. "O. aquaticum" is endemic to the eastern United States and is found growing in ponds, streams, and shallow lakes. It prefers an acidic environment. The leaves are pointed and oval with a water repellent surface. The inflorescence is most notable for having an extremely small almost indistinguishable sheath surrounding the spadix. Very early in the flowering this green sheath withers away leaving only the spadix. The sheath was originally classified by Adolf Engler as a spathe due it being the last foliar piece before the spadix. He also noted that species lacked a sympodial leaf. However, in a 1988 paper by Thomas Ray, he argued that the structure was misidentified by Engler and was actually a sympodial leaf. According to Ray the spathe was missing and not the sympodial leaf. This interpretation was determined based on observations of morphological charactestics namely the appearance of a two-keeled bracteole and its positioning. Despite this, the floral structure is still commonly identified in the literature as being a spathe. The flowering occurs in the spring. Native Americans once ate the seeds and rhizome by drying them out and grinding them into a starchy substance.
Document 2: Calendula: Calendula ( ), is a genus of about 15–20 species of annual and perennial herbaceous plants in the daisy family Asteraceae that are often known as marigolds. They are native to southwestern Asia, western Europe, Macaronesia, and the Mediterranean. Other plants are also known as marigolds, such as corn marigold, desert marigold, marsh marigold, and plants of the genus "Tagetes".
Document 3: Chamaemelum: Chamaemelum is a small genus of plants in the daisy family commonly known as chamomiles or dogfennels. Perhaps the best-known species is Roman chamomile, "Chamaemelum nobile". These are annual or perennial herbs, rarely exceeding half a meter in height and usually bearing solitary white daisylike flowers with yellow centers. They are native to Europe but most species can be found scattered in other continents where they have been introduced.
Document 4: Misopates orontium: Misopates orontium is a herbaceous annual plant of the family Plantaginaceae. It is a native of disturbed ground in Europe. It is also naturalised as a weed in other parts of the world such as North America. The pink flowers resemble a miniature Snapdragon and are followed by a hairy green fruit which is said to resemble a weasel's snout.
Document 5: Chrysanthemum: Chrysanthemums ( ), sometimes called mums or chrysanths, are flowering plants of the genus Chrysanthemum in the family Asteraceae. They are native to Asia and northeastern Europe. Most species originate from East Asia and the center of diversity is in China. There are countless horticultural varieties and cultivars.
Document 6: Orontioideae: Orontioideae is a subfamily of flowering plants in the Araceae family. The subfamily consists of three genera namely, "Lysichiton" (one to two species of skunk cabbage from North America and Asia), "Orontium" (golden club, one living species from eastern North America and two extinct species known from fossils), and "Symplocarpus" (several species of skunk cabbage from North America and Asia). Characteristics of Orontioideae include medium sized pollen grains and subterranean stems. Species in the subfamily have a base chromosome number of X=13.
Document 7: Argyranthemum: Argyranthemum (marguerite, marguerite daisy, dill daisy) is a genus of flowering plants belonging to the family Asteraceae. Members of this genus are sometimes also placed in the genus "Chrysanthemum".
Document 8: Cynareae: The Cynareae are a tribe of flowering plants in the daisy family (Asteraceae) and the subfamily Carduoideae. Most of them are commonly known as thistles; four of the best known genera are "Carduus", "Cynara" (containing the widely eaten artichoke), "Cirsium", and "Onopordum".
Document 9: Orontium mackii: Orontium mackii is an extinct golden club species in the family Araceae described from a series of isolated fossil leaves. The species is known from Late Cretaceous sediments exposed in the state of New Mexico in the United States of America. It is one of several extinct species placed in the living golden-club genus "Orontium".
Document 10: Argyreia: Argyreia is a genus of plants in the Convolvulaceae family.
Document 11: Orontium wolfei: Orontium wolfei is an extinct golden-club species in the family Araceae described from a series of isolated fossil leaves. The species is known from Eocene sediments exposed in the state of Washington in the United States of America and the province of British Columbia in Canada. It is one of several extinct species placed in the living golden-club genus "Orontium".
Document 12: Orontium: Orontium , sometimes called golden-club, is a genus of flowering plants in the family Araceae. The single living species in the genus is "Orontium aquaticum", while the two other described species, "Orontium mackii" and "Orontium wolfei", are known from fossils.
Document 13: Rhodanthemum: Rhodanthemum syn. "Chrysanthemopsis", "Pyrethropsis" (Moroccan daisy), is a genus of flowering plants in the family Asteraceae, mostly native to exposed rocky places in Northern Africa (Morocco and Algeria). Formerly included in either "Chrysanthemum" or "Leucanthemum", the 10 or 15 species of "Rhodanthemum" display many similarities to their former parents, with composite daisy-like flowers. They are mat-forming, prostrate perennials or subshrubs, and some are cultivated as ornamental plants.
Document 14: Acorus: Acorus is a genus of monocot flowering plants. This genus was once placed within the family Araceae (aroids), but more recent classifications place it in its own family Acoraceae and order Acorales, of which it is the sole genus of the oldest surviving line of monocots. Some older studies indicated that it was placed in a lineage (the order Alismatales), that also includes aroids (Araceae), Tofieldiaceae, and several families of aquatic monocots (e.g., Alismataceae, Posidoniaceae). However, modern phylogenetic studies demonstrate that "Acorus" is sister to all other monocots. Common names include calamus and sweet flag.
Document 15: Anthemis: Anthemis is a genus of aromatic flowering plants in the family Asteraceae, closely related to "Chamaemelum", and like that genus, known by the common name chamomile; some species are also called dog-fennel or mayweed. "Anthemis" are native to the Mediterranean region and southwest Asia east to Iran. A number of species have also become naturalized in the United Kingdom and other parts of the world.
