Question: Are Hoodia and Monardella both plant genus names?

full_context: Document 1: Hoodia macrantha: Hoodia macrantha is a succulent plant native to Namibia and the Cape Province of South Africa. It is regarded by some sources as a synonym of the accepted name for the plant, "Hoodia currorii" subsp. "currorii".
Document 2: Rhodohypoxis: Rhodohypoxis is a small genus of tuberous flowering plants in the family Hypoxidaceae, native to southern Africa (South Africa, Lesotho, Swaziland). The small flowers, no more than 15 cm high, are constructed so that their centres are not visible. Some species are in cultivation.
Document 3: Monardella exilis: Monardella exilis, with the common names Mojave monardella and desert monardella, is an annual plant in the "Monardella" genus of the mint family (Lamiaceae).
Document 4: Gomphocarpus fruticosus: Gomphocarpus fruticosus (syn. "Asclepias fruticosa") is a species of milkweed native to South Africa. It is also common in New Zealand where it is the main host of the monarch butterfly. The plant's tissues contain sufficient cardenolides that consumption of significant quantities of the plant's leaves, stems, or fruit may lead to death in livestock and humans.
Document 5: Monardella: Monardella is a genus of approximately 40 species of annual and perennial plants native to western North America from British Columbia to northwestern Mexico. They are grown for their highly aromatic foliage, which in some species is used for herbal teas. The two-lipped, tubular flowers are formed in terminal clusters and are most usually red, pink, or purple.
Document 6: Monardella hypoleuca: Monardella hypoleuca is a species of flowering plant in the mint family, known by the common names thickleaf monardella and white leaf monardella.
Document 7: Hoodia: Hoodia (known locally as "ghaap" or "bobbejaanghaap") is a genus of flowering plants in the family Apocynaceae, under the subfamily Asclepiadoideae, native to Southern Africa.
Document 8: Monardella lanceolata: Monardella lanceolata is a species of flowering plant in the mint family known by the common names mustang mint and mustang monardella. It is native to the mountains of California and Baja California, where it grows in chaparral, woodland, rocky slopes, and often disturbed habitat types.
Document 9: Verbena menthifolia: Verbena menthifolia is a species of verbena known by the common name mint-leaved vervain or mint vervain. It is native to the southwestern United States and northern Mexico, where it occurs in many types of open, dry habitat such as desert scrub. This perennial herb produces one or more rough-haired, erect stems up to about 75 centimeters in maximum height. The hairy leaves are a few centimeters long and are divided near the base into a few narrow lobes which have serrated edges. The inflorescence is made up of one to three narrow, erect spikes of flowers up to 30 centimeters long. The flowers are spaced, not densely packed on the slender spike. Each flower has a small purple corolla 2 or 3 millimeters wide.
Document 10: Fockea edulis: Fockea edulis is a species of plant in the Apocynaceae family that is native to South Africa and Namibia. A common name is Hottentot bread due to the milky, somewhat sweetish flavour of the edible root which is sometimes gathered from the wild for local use. The plant's latex is said to be poisonous. In Afrikaans the plant is called Bergbaroe, Bergkambroo, Kambaroo, Kambroo, Kambro, or Hotnotswaatlemoen. In Khoi it is called !Koo, !Ku, or !Kuu. A semi-deciduous perennial caudiciform with fat, twisted grey roots, it grows in warmer drier areas, dry savannah and rockery. In the wild, the caudex is partially or totally buried and tends to grow faster this way up to 60 cm in diameter. Fockeas are dioecious, so a male plant and a female plant are needed to produce seeds. The flowers are whitish-green, not very showy but lightly scented, small (0.6-1.5 cm wide) vygie-like flowers surrounded by a large, thick, spider-like calyx. The flowers are pollinated by fruit flies. The plant produces grey-greenish pods. The thin vine branches may reach a length of up to 4 meters, and climb on any type of available support. The leaves are green, entire and oblong. Although it shows decreased activity in the January – April period, it never goes into complete dormancy and always carries some leaves. Plants cannot tolerate more than occasional light frosts with temperatures dropping as low as -2°C. This species is of easy cultivation and hardy when kept reasonably dry and watered only enough to keep the tuber from shriveling.
Document 11: 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 12: Monardella stebbinsii: Monardella stebbinsii is a rare species of flowering plant in the mint family known by the common names Feather River monardella and Stebbins' monardella. It is endemic to Plumas County, California, where it is known from only about ten occurrences along the North Fork of the Feather River in the High Sierra. It is a member of the serpentine soils flora in rocky mountain habitat.
Document 13: Penstemon rupicola: Penstemon rupicola is a species of penstemon known by the common name cliff beardtongue. It is native to the west coast of the United States from Washington to the Klamath Mountains of far northern California, where it grows in rocky mountainous habitat. It is a clumpy, mat-forming subshrub growing no more than 14 centimeters high. The thick, waxy, oppositely arranged leaves are round or oval and up to 2 centimeters long. The showy wide-mouthed tubular flowers emerging from the mat may be nearly 4 centimeters in length and are shades of light purple to bright pink.
Document 14: Monardella purpurea: Monardella purpurea is a species of flowering plant in the mint family known by the common names Siskiyou monardella and serpentine monardella.
Document 15: Hoodia gordonii: Hoodia gordonii, also known as Bushman's hat, is a leafless spiny succulent plant supposed to have therapeutic properties in folk medicine. It grows naturally in Botswana, South Africa and Namibia. The species became internationally known and threatened by collectors, after a marketing campaign falsely claimed that it was an appetite suppressant for weight loss. The flowers smell like rotten meat and are pollinated mainly by flies. The indigenous San people (Bushmen) of the Namib desert call this plant ǁhoba (pronounced – the initial sound is a lateral click) – and the Afrikaans name ghaap is used to refer to all species of "Hoodia".
