Question: Are both Hottonia and Othonna geniuses of plants?

full_context: Document 1: Nymphaea: Nymphaea is a genus of hardy and tender aquatic plants in the family Nymphaeaceae. The genus has a cosmopolitan distribution. Many species are cultivated as ornamental plants, and many cultivars have been bred. Some taxa occur as introduced species where they are not native, and some are weeds. Plants of the genus are known commonly as water lilies. The genus name is from the Greek νυμφαια, "nymphaia" and the Latin "nymphaea", which mean "water lily" and were inspired by the nymphs of Greek and Latin mythology.
Document 2: Aponogeton distachyos: Aponogeton distachyos or "Aponogeton distachyum", also known as waterblommetjie ("lit. trans." water-floret), Cape-pondweed, water hawthorn, vleikos and Cape pond weed is an aquatic flowering plant.
Document 3: Dimorphotheca: Dimorphotheca is a genus of plants in the sunflower family, native to Africa and Australia. is one of eight genera of the Calenduleae, with a centre of diversity in Southern Africa. Some species can hybridize with "Osteospermum", and crosses are sold as cultivated ornamentals. The name ""Dimorphotheca"" comes from the Greek "Dis" "Morphe" and "Theka", meaning "two shaped fruit", referring to the dimorphic cypselae, a trait inherent to members of the Calenduleae. Plants of this genus usually have bisexual flowers.
Document 4: Ochna: Ochna is a genus comprising 86 species of evergreen trees, shrubs and shrublets belonging to the family "Ochnaceae". These species are native to tropical woodlands of Africa, the Mascarenes and Asia. Species of this genus are usually called Ochnas, Bird's-eye bushes or Mickey-mouse plants, a name derived from the shape of the drupelet fruit. The name of this genus comes from the Greek word "Ochne", used by Homer and meaning "wild pear", as the leaves are similar in appearance. Some species, especially "Ochna serrulata" (bird's eye plant), are widely cultivated as decorative plants.
Document 5: Thonningia: Thonningia is a monotypic genus of flowering plants in the family Balanophoraceae containing the single species Thonningia sanguinea. It is distributed throughout much of southern and western Africa, particularly the tropical regions. Common names for the plant include ground pineapple. A familiar plant to humans, it has an extremely long list of common names in many African languages. Many names are inspired by the resemblance of the plant's inflorescence to a pineapple or palm tree. Some of the names can be translated as pineapple of the bush (from Anyi), duiker's kolanut (from Igala), and crown of the ground (from Yoruba).
Document 6: Aeonium: Aeonium (tree houseleek) is a genus of about 35 species of succulent, subtropical plants of the family Crassulaceae. Many species are popular in horticulture. The genus name comes from the ancient Greek "aionos" (ageless). While most of them are native to the Canary Islands, some are found in Madeira, Morocco, and in East Africa (for example in the Semien Mountains of Ethiopia).
Document 7: Opuntia: Opuntia is a genus in the cactus family, Cactaceae.
Document 8: Nelumbonaceae: Nelumbonaceae, sometimes called the sacred lotus family, is a family of flowering plants, including the single genus "Nelumbo" with two species, "N. lutea" (North America) and "N. nucifera" (widespread in tropical Asia).
Document 9: Othonna: Othonna is a genus of African plants in the sunflower family.
Document 10: Alismataceae: The water-plantains (Alismataceae) are a family of flowering plants, comprising 11 genera and between 85 and 95 species. The family has a cosmopolitan distribution, with the greatest number of species in temperate regions of the Northern Hemisphere. Most of the species are herbaceous aquatic plants growing in marshes and ponds.
Document 11: Hottonia: Hottonia is a genus of aquatic flowering plants in the family Primulaceae. It comprises two species:
Document 12: Kleinia: Kleinia is a genus of African flowering plants in the sunflower family.
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: 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 15: Boltonia: Boltonia is a genus of plants in the sunflower family native primarily to North America with one species in eastern Asia.
