Question: Are Ornithogalum and Monstera both flowering plants?

full_context: Document 1: Galanthus elwesii: Galanthus elwesii (Elwes's snowdrop, greater snowdrop) is one of a number of species of the genus "Galanthus", herbaceous, perennial, bulbous plants belonging to the family Amaryllidaceae. It is a native of the Caucasus.
Document 2: Spathiphyllum: Spathiphyllum is a genus of about 40 species of monocotyledonous flowering plants in the family Araceae, native to tropical regions of the Americas and southeastern Asia. Certain species of "Spathiphyllum" are commonly known as Spath or peace lilies.
Document 3: 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 4: Monstera adansonii: Monstera adansonii, the Adanson's monstera or five holes plant, is a species of flowering plant from Araceae family which is widespread across much of South America and Central America. Besides South American countries it can also be found in the West Indies on islands such as Antigua, Grenada, Saba, St. Kitts, Guadeloupe, Marie Galante, Dominica, Martinique, St. Lucia, St. Vincent, Tobago, and Trinidad. The species are quite common near river valleys at lower elevations.
Document 5: Ipheion: The flowering plant genus Ipheion (starflower, spring starflower) belongs to Allioideae subfamily of the Amaryllidaceae family. The World Checklist of Selected Plant Families no longer recognize the genus, regarding it as a synonym of "Tristagma", although The Plant List accepts two species.
Document 6: Nepenthes: Nepenthes ( ), also known as tropical pitcher plants, is a genus of carnivorous plants in the monotypic family Nepenthaceae. The genus comprises roughly 150 species, and numerous natural and many cultivated hybrids. They are mostly liana-forming plants of the Old World tropics, ranging from South China, Indonesia, Malaysia and the Philippines; westward to Madagascar (two species) and the Seychelles (one); southward to Australia (three) and New Caledonia (one); and northward to India (one) and Sri Lanka (one). The greatest diversity occurs on Borneo, Sumatra, and the Philippines, with many endemic species. Many are plants of hot, humid, lowland areas, but the majority are tropical montane plants, receiving warm days but cool to cold, humid nights year round. A few are considered tropical alpine, with cool days and nights near freezing. The name "monkey cups" refers to the fact that monkeys have been observed drinking rainwater from these plants.
Document 7: Galanthus nivalis: Galanthus nivalis, the snowdrop or common snowdrop, is the best-known and most widespread of the 20 species in its genus, "Galanthus". Snowdrops are among the first bulbs to bloom in spring and can form impressive carpets of white in areas where they are native or have been naturalised. They should not be confused with the snowflakes, in the genera "Leucojum" and "Acis".
Document 8: Monstera: Monstera is a genus of about 50 species of flowering plants in the arum family, Araceae, native to tropical regions of the Americas. The genus is named from the Latin word for "monstrous" or "abnormal", and refers to the unusual leaves with natural holes that members of the genus have.
Document 9: Montrichardia arborescens: Montrichardia arborescens, yautia madera, or moco-moco, is a tropical plant grows along river banks, swamps, or creeks to a maximum height of 9'. They consist of arrow shaped leaves that are food sources for animal species. The plant produces inflorescences which then leave a fruit of "Montrichardia arborescens" which is edible and can be cooked. Its fruiting spadices produces large infructescences, which contain about 80 edible yellow fruits.
Document 10: 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 11: Ornithogalum: Ornithogalum is a genus of perennial plants mostly native to southern Europe and southern Africa belonging to the family Asparagaceae. Some species are native to other areas such as the Caucasus. Growing from a bulb, species have linear basal leaves and a slender stalk, up to 30 cm tall, bearing clusters of typically white star-shaped flowers, often striped with green. The common name of the genus, Star-of-Bethlehem, is based on its star-shaped flowers, after the Star of Bethlehem that appeared in the biblical account of the birth of Jesus. The number of species has varied considerably, depending on authority, from 50 to 300.
Document 12: Epipremnum: Epipremnum is a genus of flowering plants in the family Araceae, found in tropical forests from China, the Himalayas, and Southeast Asia to Australia the western Pacific. They are evergreen perennial vines climbing with the aid of aerial roots. They may be confused with other Monstereae such as "Rhaphidophora", "Scindapsus" and "Amydrium".
Document 13: Galanthus: Galanthus (snowdrop; Greek "gála" "milk", "ánthos" "flower") is a small genus of about 20 species of bulbous perennial herbaceous plants in the family Amaryllidaceae. The plants have two linear leaves and a single small white drooping bell shaped flower with six petal-like (petaloid) tepals in two circles (whorls). The smaller inner petals have green markings.
Document 14: Globularia: Globularia is a genus of about 22 species of flowering plants in the family Plantaginaceae, native to central and southern Europe, Macaronesia, northwest Africa and southwest Asia. They are dense low evergreen mat-forming perennials or subshrubs, with leathery oval leaves 1–10 cm long. The flowers are produced in dense inflorescences (capitula) held above the plant on a 1–30 cm tall stem; the capitula is 1–3 cm in diameter, with numerous tightly packed purple, violet, pink or white flowers.
Document 15: Monsteroideae: Monsteroideae is a subfamily of flowering plants in the Araceae family. It contains genera including: "Alloschemone", "Amydrium", "Anadendrum", "Epipremnum", "Heteropsis", "Holochlamys", "Monstera", "Rhaphidophora", "Rhodospatha", "Scindapsus", "Spathiphyllum", and "Stenospermation". The subfamily is notable for having many trichosclereids in the vegetative and floral parts of the plants, but rarely in the roots.
