Question: Are Aphelandra and Pithecellobium both genera of flowering plants?

full_context: Document 1: Phytelephas: Phytelephas is a genus containing six known species of palms (family Arecaceae), occurring from southern Panama along the Andes to Ecuador, Bolivia, Colombia, northwestern Brazil, and Peru. They are commonly known as ivory palms, ivory-nut palms or tagua palms; the scientific name "Phytelephas" means "plant elephant". This and the first two of the common names refer to the very hard white endosperm of their seeds (tagua nuts or jarina seeds), which resembles elephant ivory.
Document 2: Arachis: Arachis is a genus of about 70 species of annual and perennial flowering plants in the pea family (Fabaceae), native to South America, and was recently assigned to the informal monophyletic "Pterocarpus" clade of the Dalbergieae. At least one species, the peanut ("Arachis hypogaea"), is a major food crop species of global importance; some of the other species are cultivated for food to a small extent in South America. Other species such as "A. pintoi" are cultivated worldwide as forage and soil conditioner plants, with the leaves providing high-protein feed for grazing livestock and a nitrogen source in agroforestry and permaculture systems.
Document 3: Fabaceae: The Fabaceae or Papilionoideae, commonly known as the legume, pea, or bean family, is a large and economically important family of flowering plants. It includes trees, shrubs, and perennial or annual herbaceous plants, which are easily recognized by their fruit (legume) and their compound, stipulated leaves. Many legumes have characteristics of flowers and fruits. The family is widely distributed, and is the third-largest land plant family in terms of number of species, behind only the Orchidaceae and Asteraceae, with about 751 genera and some 19,000 known species. The five largest of the genera are "Astragalus" (over 3,000 species), "Acacia" (over 1000 species), "Indigofera" (around 700 species), "Crotalaria" (around 700 species) and "Mimosa" (around 500 species), which constitute about a quarter of all legume species. The ca. 19,000 known legume species amount to about 7% of flowering plant species. Fabaceae is the most common family found in tropical rainforests and in dry forests in the Americas and Africa.
Document 4: Peltops: Peltops is a genus of bird in the family Artamidae. The genus contains two species endemic to the island of New Guinea. The genus was once placed with the monarch flycatchers, but molecular and morphometric studies place it closer to the butcherbirds, possibly as a sister taxon to this group. The genus is named for the Greek "pelte" meaning small shield and "ops" meaning face. The species have also had the common name of shieldbill.
Document 5: Pithecellobium: Pithecellobium is a genus of flowering plants in the legume family, Fabaceae. The generic name is derived from the Greek words πιθηκος ("pithekos"), meaning "ape" or "monkey," and ελλοβιον ("ellobion"), meaning "earring," which refers to the coiled shape of the fruit pods. Plants of the genus are known generally as blackbeads.
Document 6: Acanthaceae: Acanthaceae is a family (the acanthus family) of dicotyledonous flowering plants containing almost 250 genera and about 2500 species. Most are tropical herbs, shrubs, or twining vines; some are epiphytes. Only a few species are distributed in temperate regions. The four main centres of distribution are Indonesia and Malaysia, Africa, Brazil, and Central America. The representatives of the family can be found in nearly every habitat, including dense or open forests, scrublands, wet fields and valleys, sea coast and marine areas, swamps, and mangrove forests.
Document 7: Eupatorieae: Eupatorieae is a tribe of over 2000 species of plants in the aster family. Most of the species are native to tropical, subtropical, and warm temperate areas of the Americas, but some are found elsewhere. Well-known members are "Stevia rebaudiana" (used as a sugar substitute), a number of medicinal plants ("Eupatorium"), and a variety of late summer to autumn blooming garden flowers, including "Ageratum" (flossflower) and "Conoclinium" (mistflower).
Document 8: Tillandsia: Tillandsia is a genus of around 650 species of evergreen, perennial flowering plants in the family Bromeliaceae, native to the forests, mountains and deserts of Central and South America, the southern United States and the West Indies. They have naturally been established in diverse environments such as equatorial tropical rain forests, high elevation Andes mountains, rock dwelling (saxicolous) regions, and Louisiana swamps, such as Spanish Moss ("T. usneoides"), a species that grows atop tree limbs. Airplant is a common name for plants in this genus. Most "Tillandsia" species are epiphytes – i.e. they normally grow without soil while attached to other plants. Some are aerophytes or "air plants", which have no roots and grow on shifting desert soil. Generally, the thinner-leafed varieties grow in rainy areas and the thick-leafed varieties in areas more subject to drought. Most species absorb moisture and nutrients through the leaves from rain, dew, dust, decaying leaves and insect matter, aided by structures called trichomes.
Document 9: Centrolobium: Centrolobium is a Neotropical genus of legume in the Fabaceae family, assigned to the informal monophyletic "Pterocarpus" clade of the Dalbergieae. The genus comprises mostly large trees to 30 m tall, characterised by an abundance of orange peltate glands that cover most parts of the plant, and fruits that are large winged samaras to 30 cm long with a spiny basal seed chamber.
Document 10: 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 11: Aphelandra: Aphelandra is a genus of about 170 species of flowering plants in the family Acanthaceae, native to tropical regions of the Americas.
Document 12: Guzmania: Guzmania (tufted airplant) is a genus of over 120 species of flowering plants in the botanical family Bromeliaceae, subfamily Tillandsioideae. They are mainly stemless, evergreen, epiphytic perennials native to Florida, the West Indies, southern Mexico, Central America, and northern and western South America. They are found at altitudes of up to 3500 m in the Andean rainforests.
Document 13: Colobanthus: Colobanthus is a large genus of small, cushion-like herbaceous plants, sometimes known as "pearlworts", a name they share with plants of the related genus "Sagina". "C. quitensis" is the world's southernmost dicot, and one of only two original flowering plants of Antarctica.
Document 14: Dieffenbachia: Dieffenbachia is a genus of tropical flowering plants in the family Araceae. It is native to the New World Tropics from Mexico and the West Indies south to Argentina. Some species are widely cultivated as ornamental plants, especially as houseplants, and have become naturalized on a few tropical islands.
Document 15: Ptelea: Ptelea is a genus of flowering plants in the citrus family, Rutaceae. The name, of Greek derivation, is the classical name of the elm tree. Carl Linnaeus used that word for this genus because of the resemblance of its fruit to that of the elm. Members of the genus are commonly known as hoptrees.
