Question: Are both Rhapidophyllum and Spartium flowering plants?

full_context: Document 1: Sparganium: Sparganium (bur-reed) is a genus of flowering plants, described as a genus by Linnaeus in 1753. It is widespread in wet areas in temperate regions of both the Northern and Southern Hemispheres. The plants are perennial marsh plants that can grow to 3.5 m (depending on the species), with epicene flowers.
Document 2: Spartium: Spartium junceum, commonly known as Spanish broom or weaver's broom, is a species of flowering plant in the family Fabaceae.
Document 3: Rhapidophyllum: Rhapidophyllum hystrix, the needle palm, is a palm, the sole member of the genus Rhapidophyllum. It is native to the subtropical southeastern United States. Endemic populations can be found from coastal southeast South Carolina, southward to Florida and west across the coastal plain of Mississippi and southern Alabama. It is one of the most cold-hardy palms in the world, and can be found growing in several areas with warm temperate climates.
Document 4: Dypsis lutescens: Dypsis lutescens, also known as golden cane palm, areca palm, yellow palm, or butterfly palm, is a species of flowering plant in the Arecaceae family, native to Madagascar and naturalized in the Andaman Islands, Réunion, El Salvador, Cuba, Puerto Rico, the Canary Islands, southern Florida, Haiti, the Dominican Republic, Jamaica, the Leeward Islands and the Venezuelan Antilles.
Document 5: Sphaeralcea: Sphaeralcea is a genus of flowering plants in the mallow family (Malvaceae). There are about 40-60 species, including annuals, perennials, and shrubs. Most originate in the drier regions of North America, with some known from South America. They are commonly known as globemallows, globe mallows, or falsemallows. The name of the genus is derived from the Greek words σφαῖρα ("sphaira"), meaning "sphere," and αλκεα ("alkea"), meaning "mallow."
Document 6: Polygonum spergulariiforme: Polygonum spergulariiforme is a North American species of flowering plants in the buckwheat family known by the common name spurry knotweed or fall knotweed. It grows in western Canada (British Columbia and Saskatchewan) and the western United States (primarily Washington, Oregon, and northern and central California but with a few isolated populations in Idaho, Wyoming and Montana).
Document 7: Phoenix (plant): Phoenix is a genus of 14 species of palms, native to an area starting from the Canary Islands in the west, across northern and central Africa, to the extreme southeast of Europe (Crete), and continuing throughout southern Asia from Turkey east to southern China and Malaysia. The diverse habitats they occupy include swamps, deserts, and mangrove sea coasts. Most "Phoenix" species originate in semiarid regions, but usually occur near high groundwater levels, rivers, or springs. The genus is unusual among members of the subfamily Coryphoideae, with it and "Arenga" being the only ones with pinnate, rather than palmate leaves.
Document 8: Ulex europaeus: Ulex europaeus (gorse, common gorse, furze or whin) is a species of flowering plant in the family Fabaceae, native to portions of Europe from the northern United Kingdom south to Portugal, and from the western Republic of Ireland east to Galicja in Poland and Ukraine.
Document 9: Retama: Retama is a genus of flowering bushes in the legume family, Fabaceae. It belongs to the broom tribe, Genisteae. "Retama" broom bushes are found natively in North Africa, the Levant and some parts of southern Europe. "Retama raetam" and "Retama monosperma" have white flowers, while "Retama sphaerocarpa" has yellow flowers. It remains an open question in taxonomy whether the members of the "Retama" genus should be incorporated into the genus "Genista" (see Genisteae). The name traces itself to the Hebrew "רותם (Pronounced Rotem)"
Document 10: 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 11: Lygodium palmatum: Lygodium palmatum is the only species of its genus native to North America. Unlike most species in the genus, this one, called the American climbing fern (or Hartford fern, after Hartford, Connecticut), is extremely hardy in temperate zones.
Document 12: Roystonea: Roystonea is a genus of eleven species of monoecious palms, native to the Caribbean Islands, and the adjacent coasts of Florida and Central and northern South America. Commonly known as the royal palms, the genus was named for Roy Stone, a U.S. Army engineer. It contains some of the most recognizable and commonly cultivated palms in tropical and subtropical regions.
Document 13: Genista: Genista is a genus of flowering plants in the legume family Fabaceae, native to open habitats such as moorland and pasture in Europe and western Asia. They include species commonly called broom, though the term may also refer to other genera, including "Cytisus" and "Chamaecytisus". Brooms in other genera are sometimes considered synonymous with "Genista": "Echinospartum", "Retama", "Spartium", "Stauracanthus", and "Ulex".
Document 14: Colpothrinax: Colpothrinax is a genus of palms native to Central America and the Caribbean. "Colpothrinax aphanopetala" is found in southern Central America (from southeast Nicaragua to Panama), while "Colpothrinax cookii" is found in northern Central America (from Belize to Honduras). The third species, "Colpothrinax wrightii", is endemic to southwest Cuba including the Isle of Youth.
Document 15: Sarcopoterium: Sarcopoterium is a genus of flowering plants in the rose family. The genus is synonymous to "Poterium". The sole species within this genus, Sarcopoterium spinosum, is common to the southeast Mediterranean region and Middle East. It is a perennial bush with small flowers in inflorescence. "Sarcopoterium spinosum" flowers in February to April and its fruits mature in autumn, then fall to earth to germinate with the rain water.
