Question: Are Vernonia and Orthophytum both from the same family?
Context: Vernonia arkansana (also known as Arkansas ironweed and great ironweed) is a species of perennial plant from Asteraceae family that can be found in south-central United States.  The plant is 4 - high and 3 - wide.  The flowers bloom from August to September and are pink-purple coloured. Orthophytum (Greek "ortho" = straight and "phytum" = plant) is a genus of the botanical family Bromeliaceae, subfamily Bromelioideae. Vernonia is a genus of about 1000 species of forbs and shrubs in the family Asteraceae.  Some species are known as ironweed.  Some species are edible and of economic value.  They are known for having intense purple flowers.  The genus is named for the English botanist William Vernon.  There are numerous distinct subgenera and subsections in this genus.  This has led some botanists to divide this large genus into several distinct genera.  For instance, the "Flora of North America" only recognizes about 20 species in "Vernonia" sensu stricto, 17 of which are in North America north of Mexico, with the others being found in South America. Vernonia galamensis is a plant in the sunflower family, known for its use as an oilseed.  This species, often called ironweed, is the largest source of vernonia oil, which is rich in a useful epoxy fatty acid called vernolic acid and is used to make plastics, rubbery coatings, and drying agents.  Use of this oil as a replacement for traditional plasticizers and binders in the production of paints and PVC shows promise as a method of reducing smog pollution. Vernonia blodgettii (Florida ironweed, Blodgett's ironweed) is a species of perennial plant from Asteraceae family that is native to Florida and the Bahamas. Vernonia missurica, the Missouri ironweed, is a species of purple colored perennial plant from Asteraceae family that can be found growing in the central United States. Vernonia gigantea (also known as giant ironweed, tall ironweed or ironweed) is a species of perennial plant from Asteraceae family that can be found in United States and Canada.  The plant is native to the eastern United States, north to New York state and Ontario, and southwest to Texas. 'Blaze' is a hybrid cultivar of the genus "Orthophytum" in the Bromeliad family. Vernonia amygdalina, a member of the Asteraceae family, is a small shrub that grows in tropical Africa.  "V. amygdalina" typically grows to a height of 2-5 m .  The leaves are elliptical and up to 20 cm long.  Its bark is rough.  "V. amygdalina" is commonly called bitter leaf in English because of its bitter taste.  The cooked leaves are a staple vegetable in soups and stews of various cultures throughout equatorial Africa.  African common names include grawa (Amharic), ewuro (Yoruba), etidot (Ibibio), onugbu (Igbo), ityuna (Tiv), oriwo (Edo), chusar-doki (Hausa), mululuza (Luganda), labwori (Acholi), olusia (Luo), and ndoleh (Cameroon). Tarlmounia is a plant genus in the family Asteraceae.  The sole species is Tarlmounia elliptica (syn.  "Vernonia elliptica" and "V. elaeagnifolia"), native to India, Burma and Thailand and naturalised in southern Taiwan and Queensland, Australia.  Common names include curtain creeper, vernonia creeper and parda bel.
