Question: Is Lysichiton and Ageratum geus in the same family?

full_context: Document 1: 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 2: Tridax procumbens: Tridax procumbens, commonly known as coatbuttons or tridax daisy, is a species of flowering plant in the daisy family. It is best known as a widespread weed and pest plant. It is native to the tropical Americas, but it has been introduced to tropical, subtropical, and mild temperate regions worldwide. It is listed as a noxious weed in the United States and has pest status in nine states.
Document 3: Achillea ageratum: Achillea ageratum, also known as sweet yarrow, sweet-Nancy, or sweet maudlin, is a flowering plant in the sunflower family, native to southern Europe (Spain, Portugal, France, Italy, Greece, Balkans). It is cultivated in many places for its pleasant fragrance and sparingly naturalized in a few places outside its native range.
Document 4: Arum: Arum is a genus of flowering plants in the family Araceae, native to Europe, northern Africa, and western and central Asia, with the highest species diversity in the Mediterranean region. Frequently called "arum lilies", they are not closely related to the true lilies "Lilium". Plants in closely related "Zantedeschia" are also called "arum lilies".
Document 5: Antennaria: Antennaria is a genus of herbaceous perennial plants in the family Asteraceae, native to temperate regions of the Northern Hemisphere, with one species ("A. chilensis") in temperate southern South America; the highest species diversity is in North America. Common names include catsfoot or cat's-foot, pussytoes and everlasting.
Document 6: Zantedeschia aethiopica: Zantedeschia aethiopica (known as calla lily and arum lily) is a species in the family Araceae, native to southern Africa in Lesotho, South Africa, and Swaziland.
Document 7: Matricaria discoidea: Matricaria discoidea, commonly known as pineappleweed, wild chamomile, and disc mayweed is an annual plant native to North America and Northeast Asia but which has become a cosmopolitan weed. It is in the family Asteraceae. The flowers exude a chamomile/pineapple aroma when crushed. They are edible and have been used in salads (although they may become bitter by the time the plant blooms) and to make herbal tea. Pineapple weed has been used for medicinal purposes, including for relief of gastrointestinal upset, infected sores, fevers, and postpartum anemia.
Document 8: Ageratum: Ageratum ( ), (whiteweed in the USA), is a genus of 40 to 60 tropical and warm temperate flowering annuals and perennials from the family Asteraceae, tribe Eupatorieae. Most species are native to Central America and Mexico but four are native to the United States.
Document 9: 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.
Document 10: Lysichiton: Lysichiton is a genus in the family Araceae. These plants are known commonly as skunk cabbage or less often as swamp lantern. The spelling Lysichitum is also found. The genus has two species, one found in north-east Asia (Japan and Russian Far East), the other in north-west America (Aleutians to Santa Cruz County in California).
Document 11: Lysichiton americanus: Lysichiton americanus, also called western skunk cabbage (USA), yellow skunk cabbage (UK), American skunk-cabbage (Britain and Ireland) or swamp lantern, is a plant found in swamps and wet woods, along streams and in other wet areas of the Pacific Northwest, where it is one of the few native species in the arum family. The plant is called skunk cabbage because of the distinctive "skunky" odor that it emits when it blooms. This odor will permeate the area where the plant grows, and can be detected even in old, dried specimens. The distinctive odor attracts its pollinators, scavenging flies and beetles. Although similarly named and with a similar smell, the plant is easy to distinguish from the eastern skunk cabbage ("Symplocarpus foetidus"), another species in the arum family found in eastern North America.
Document 12: 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 13: 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 14: Ribes glandulosum: Ribes glandulosum, the skunk currant, is a North American species of flowering plant in the currant family. It is widespread in Canada (all 10 provinces and all 3 territories) and is also found in parts of the United States (Alaska, the Great Lakes region, the Appalachian Mountains, and the Northeast).
Document 15: Erigeron annuus: Erigeron annuus (annual fleabane, daisy fleabane, or eastern daisy fleabane) is a North American plant species in the daisy family.
