Question: Cestrum and Ericaceae, are types of what?

full_context: Document 1: Epacris: Epacris is a genus of about 35–40 species of flowering plants in the family Ericaceae. It was formerly treated in a closely related but separate family Epacridaceae, but the various genera within Epacridaceae including "Epacris" have been revised in their relationships to each other and brought under the common umbrella of the Ericaceae. The genus "Epacris" is native to eastern and southeastern Australia (southeast Queensland south to Tasmania and west to southeast South Australia), New Caledonia and New Zealand. The species are known as heaths or Australian heaths.
Document 2: Cestrum: Cestrum is a genus of - depending on authority - 150-250 species of flowering plants in the family Solanaceae. They are native to warm temperate to tropical regions of the Americas, from the southernmost United States (Florida, Texas: day-blooming cestrum, "C. diurnum") south to the Bío-Bío Region in central Chile (green cestrum, "C. parqui"). They are colloquially known as cestrums or jessamines (from "jasmine", due to their fragrant flowers).
Document 3: Zinnia: Zinnia is a genus of plants of the sunflower tribe within the daisy family. They are native to scrub and dry grassland in an area stretching from the Southwestern United States to South America, with a centre of diversity in Mexico. Members of the genus are notable for their solitary long-stemmed flowers that come in a variety of bright colors. The genus name honors German master botanist Johann Gottfried Zinn (1727–59).
Document 4: Datura: Datura is a genus of nine species of poisonous vespertine flowering plants belonging to the family Solanaceae. They are commonly known as daturas, but also known as devil's trumpets, not to be confused with angel's trumpets, its closely related genus "Brugmansia". They are also sometimes called moonflowers, jimsonweed, devil's weed, hell's bells, thorn-apple, and many more. Its precise and natural distribution is uncertain, owing to its extensive cultivation and naturalization throughout the temperate and tropical regions of the globe. Its distribution within the Americas and North Africa, however, is most likely restricted to the United States and Mexico and Southern Canada in North America, and Tunisia in Africa, where the highest species diversity occurs.
Document 5: Eustoma: Eustoma, commonly known as lisianthus or prairie gentian, is a small genus in the gentian family. They are native to warm regions of the southern United States, Mexico, Caribbean and northern South America. This genus is typically found in grasslands and in areas of disturbed ground.
Document 6: Berberidaceae: The Berberidaceae are a family of 14 genera flowering plants commonly called the barberry family. This family is in the order Ranunculales. The family contains about 700 known species, of which the majority are in "Berberis". The species include trees, shrubs and perennial herbaceous plants.
Document 7: Ericaceae: The Ericaceae are a family of flowering plants, commonly known as the heath or heather family, found most commonly in acid and infertile growing conditions. The family is large, with c. 4250 known species spread across 124 genera, making it the 14th most species-rich family of flowering plants. The many well-known and economically important members of the Ericaceae include the cranberry, blueberry, huckleberry, rhododendron (including azaleas), and various common heaths and heathers ("Erica", "Cassiope", "Daboecia", and "Calluna" for example).
Document 8: List of Rhododendron species: This List of "Rhododendron" species includes species of the genus "Rhododendron", which is in the plant family Ericaceae. Depending on the source, there are anywhere from 800 to over 1,100 wild species. The vast majority of "Rhododendron" species are native to the eastern Himalaya and southeast Tibet, along with the islands of Java, Sumatra, Borneo, New Guinea, and the Philippines. The rest are broadly spread throughout the northern hemisphere in relatively small isolated populations, including Japan, northwestern North America, the Appalachian, and the Caucasus Mountains.
Document 9: 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 10: Plumeria rubra: Plumeria rubra is a deciduous plant species belonging to the genus "Plumeria". Originally native to Mexico, Central America, Colombia and Venezuela, it has been widely cultivated in subtropical and tropical climates worldwide and is a popular garden and park plant, as well as being used in temples and cemeteries. It grows as a spreading tree to 7 – high and wide, and is flushed with fragrant flowers of shades of pink, white and yellow over the summer and autumn. Its common names include frangipani, red paucipan, red-jasmine, red frangipani, common frangipani, temple tree, or simply plumeria.
Document 11: Erica: Erica is a genus of roughly 860 species of flowering plants in the family Ericaceae. The English common names "heath" and "heather" are shared by some closely related genera of similar appearance. The genus "Calluna" was formerly included in "Erica" – it differs in having even smaller scale-leaves (less than 2–3 mm long), and the flower corolla consisting of separate petals. "Erica" is sometimes referred to as "winter (or spring) heather" to distinguish it from "Calluna" "summer (or autumn) heather".
Document 12: Ericaceous bed: An Ericaceous bed is a bed (or garden) with acidic and often nutrient-poor soil such as Ericaceous compost and different types of peat. The pH of the soil is typically between 4.5 and 6. The purpose is typically to grow a number of garden plants which require (or thrives best in) acidic soil. Such plants commonly include heathers (Erica, Calluna and more) and Rhododendrons. Another group of plants common in ericaceous beds are those belonging to the boreal coniferous forest, e.g. Vacciniums. A number of orchids also grow well in nutrient-poor soil.
Document 13: Rhododendron: Rhododendron (from Ancient Greek ῥόδον "rhódon" "rose" and δένδρον "déndron" "tree") is a genus of 1,024 species of woody plants in the heath family (Ericaceae), either evergreen or deciduous, and found mainly in Asia, although it is also widespread throughout the highlands of the Appalachian Mountains of North America. It is the national flower of Nepal. Most species have brightly coloured flowers which bloom from late winter through to early summer.
Document 14: Plumeria: Plumeria ( ) is a genus of flowering plants in the dogbane family, Apocynaceae. Most species are deciduous shrubs or small trees. The species variously are indigenous to Mexico, Polynesia, Central America, and the Caribbean, and as far south as Brazil, but are grown as cosmopolitan ornamentals in warm regions. Common names for plants in the genus vary widely according to region, variety, and whim, but frangipani or variations on that theme are the most common. Plumeria also is used directly as a common name, especially in horticultural circles.
Document 15: Gaylussacia: Gaylussacia is a genus of about fifty species of flowering plants in the family Ericaceae, native to the Americas, where they occur in eastern North America and in South America in the Andes and the mountains of southeastern Brazil (the majority of the known species). Common English names include huckleberry (shared with plants in several other genera) and "dangleberry".
