Question: Are both Cissus and Ruscus considered flowering plants?

full_context: Document 1: 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 2: Asperula: Asperula, commonly known as woodruff, is a genus of flowering plants in the Rubiaceae family. It contains about 195 species and has a wide distribution area from Europe, northern Africa, temperate and subtropicale Asia to Australasia.
Document 3: Rhoicissus: Rhoicissus is an Afrotropical plant genus in the grape family Vitaceae and Vitoideae subfamily. There are between 9 and 22 accepted species.
Document 4: Beaucarnea: Beaucarnea is a genus of flowering plants native to Mexico and Central America. In the APG III classification system, it is placed in the family Asparagaceae, subfamily Nolinoideae (formerly the family Ruscaceae). "Beaucarnea" is sometimes treated as a synonym of the genus "Nolina", with the species being then transferred to that genus. However, recent research shows that "Beaucarnea" should treated as an independent genus.
Document 5: Parthenocissus quinquefolia: Parthenocissus quinquefolia, known as Virginia creeper, Victoria creeper, five-leaved ivy, or five-finger, is a species of flowering plant in the grape family, Vitaceae. It is native to eastern and central North America, from southeastern Canada and the eastern United States west to Manitoba and Utah, and south to eastern Mexico and Guatemala.
Document 6: Ampelocissus africana: Ampelocissus africana is a type of vine that is woody, or liana of the grape family, bearing edible fruit. It is native to habitats in, and around forested areas in Guinea, Ivory Coast, Nigeria, Cameroon, Chad, Central African Republic, Sudan, Kenya, Rwanda, Burundi, Tanzania (including the Zanzibar Archipelago, from where the type specimen was collected), Malawi, Zambia, Mozambique, Zimbabwe and Botswana. It was originally described botanically in 1790 by João de Loureiro as "Botria africanus", which is the basionym for its treatment here under "Ampelocissus".
Document 7: Celastraceae: The Celastraceae (syn. Brexiaceae, Canotiaceae, Chingithamnaceae, Euonymaceae, Parnassiaceae, Siphonodontaceae, and Stackhousiaceae), are a family (the staff vine or bittersweet family) of 96 genera and 1,350 species of herbs, vines, shrubs and small trees, belonging to the order Celastrales. The great majority of the genera are tropical, with only "Celastrus" (the staff vines), "Euonymus" (the spindles) and "Maytenus" widespread in temperate climates.
Document 8: Parthenocissus vitacea: Parthenocissus vitacea (syn. "P. inserta"), also known as thicket creeper, false Virginia creeper, woodbine, or grape woodbine, is a woody vine native to North America, in southeastern Canada (west to southern Manitoba) and a large area of the United States, from Maine west to Montana and south to New Jersey and Missouri in the east, and Texas to Arizona in the west. It is present in California, but it may be an introduced species that far west.
Document 9: Ruscus: Ruscus is a genus of six species of flowering plants, native to western and southern Europe (north to southern England), Macaronesia, northwest Africa, and southwestern Asia east to the Caucasus. In the APG III classification system, it is placed in the family Asparagaceae, subfamily Nolinoideae (formerly the family Ruscaceae). Like many lilioid monocots, it was formerly classified in the family Liliaceae.
Document 10: Romulea bulbocodium: Romulea bulbocodium is one of the best-known species from the genus "Romulea". The plant, a member of the Iridaceae family, is native to the Mediterranean region (southern Europe, northern Africa, the Middle East) and Sudan. It has many varieties and is occasionally used as ornamental plant.
Document 11: Cissus elegans: Cissus elegans is a species of flowering plants in the family Vitaceae.
Document 12: Calibanus: Calibanus is a genus of two species of flowering plants, both evergreen succulents from dry areas of northeastern Mexico. The APG III classification system places it in the family Asparagaceae, subfamily Nolinoideae (formerly the family Ruscaceae. ) It was formerly included in the Agavaceae (now Agavoideae) but is now separated from them, for it is polycarpic and dioecious. Its name refers to the monster Caliban, an antagonist in Shakespeare's "The Tempest".
Document 13: Cissus: Cissus is a genus of approximately 350 species of lianas (woody vines) in the grape family (Vitaceae). They have a cosmopolitan distribution, though the majority are to be found in the tropics.
Document 14: Ruta: Ruta (commonly known as rue) is a genus of strongly scented evergreen subshrubs, 20–60 cm tall, in the family Rutaceae, native to the Mediterranean region, Macaronesia and southwest Asia. There are perhaps 8 to 40 species in the genus. The most well-known species is "Ruta graveolens" (rue or common rue).
Document 15: Vitaceae: The Vitaceae are a family of dicotyledonous flowering plants, with 14 genera and ca 910 known species, including the grapevine and Virginia creeper. The family name is derived from the genus "Vitis". The name sometimes appears as Vitidaceae, but Vitaceae is a conserved name and therefore has priority over both Vitidaceae and another name sometimes found in the older literature, Ampelidaceae. In the APG III system (2009) onwards, the family is placed in its own order, Vitales. Molecular phylogenetic studies place the Vitales as the most basal clade in the rosids.
