Question: Acorus and Clivia, are which specific genus?

full_context: Document 1: 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 2: Iris pseudacorus: Iris pseudacorus (yellow flag, yellow iris, water flag, lever) is a species in the genus "Iris", of the family Iridaceae. It is native to Europe, western Asia and northwest Africa. Its specific epithet, meaning "false acorus", refers to the similarity of its leaves to those of "Acorus calamus", as they have a prominently veined mid-rib and sword-like shape.
Document 3: Acorus calamus: Acorus calamus (also called sweet flag or calamus, among many common names) is a tall perennial wetland monocot of the Acoraceae family, in the genus "Acorus".
Document 4: 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 5: Calloideae: Calloideae is a monotypic subfamily of flowering plants in the Araceae family. The single genus in the family is Calla, although in the past under Engler's description of Araceae it included four genera, namely Lysichiton, Symplocarpus, Orontium, and Calla. The subfamily was subsequently made monotypic and given a single tribe, Callea. Species in Calloideae are often found in marshy habitats in the northern hemisphere. Trichosclereids are not found in the flowers.
Document 6: Clivia: Clivia is a genus of monocot flowering plants native to southern Africa. They are from the family Amaryllidaceae, subfamily Amaryllidoideae. Common names are "Natal lily" or "bush lily".
Document 7: Clivia nobilis: Clivia nobilis (green-tip forest lily), is a species of flowering plant in the genus "Clivia", of the family Amaryllidaceae, native to South Africa. It grows to about 38 cm . It has evergreen strap-shaped leaves, and bears pendent umbels of multiple narrow, trumpet-shaped, red and yellow flowers, tipped with green.
Document 8: Calamus (palm): Calamus is a genus of the palm family Arecaceae. These are among several genera known as rattan palms. There are an estimated 400 species in this genus, all native to tropical and subtropical Asia, Africa, and Australia. They are mostly leaf-climbing lianas with slender, reedy stems. To aid scrambling some species have evolved hooks on the underside of the midrib, or more commonly by modified "pinnae" or tendrils in the form of stout, backward-pointing spines. These stems may grow to lengths of 200 metres.
Document 9: Scadoxus: Scadoxus is a genus of African and Arabian plants in the Amaryllis family, subfamily Amaryllidoideae. The English name "blood lily" is used for some of the species. The genus has close affinities with "Haemanthus." Species of "Scadoxus" are grown as ornamental plants for their brilliantly coloured flowers, either in containers or in the ground in frost-free climates. Although some species have been used in traditional medicine, they contain poisonous alkaloids.
Document 10: 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 11: Clivia miniata: Clivia miniata (Natal lily, bush lily, Kaffir lily) is a species of flowering plant in the genus "Clivia" of the family Amaryllidaceae, native, growing in woodland habitats in South Africa (Eastern Cape, Mpumalanga and KwaZulu-Natal provinces) as well as in Swaziland. Given suitable conditions it grows into large clumps and is surprisingly water wise. It is also reportedly naturalized in Mexico. It is a popular plant for shady areas and is commonly seen growing in older established suburbs in most Australian states. It is also popular in New Zealand, Japan, China and southern parts of the USA , particularly California.
Document 12: Alismatid monocots: Alismatid monocots (alismatids, "basal monocots") is an informal name for a group of early branching (hence basal) monocots, consisting of two orders, the Acorales and Alismatales. The name has also been used to refer to the Alismatales alone. Monocots are frequently treated as three informal groupings based on their branching from ancestral monocots and shared characteristics: alismatid monocots, lilioid monocots (the five other non-commelenid monocots) and commelinid monocots. Research at the Royal Botanical Gardens, Kew is organised into two teams I: Alismatids and Lilioids and II: Commelinids. A similar approach is taken by Judd in his Plant systematics. They also organise their monocot research into two teams I: Alismatids and Lilioids, and II: Commelinids. A similar approach is taken by Judd in his "Plant systematics".
Document 13: 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 14: 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 15: Acorus gramineus: Acorus gramineus, commonly known as grass-leaf sweet flag, dwarf sedge, Japanese rush, and Japanese sweet flag, is a botanical species belonging to the genus Acorus, native to Japan, Korea in eastern Asia. The plant usually grows in wetlands and shallow water.
