Question: Ulex and Vernonia are both what?
Context: The Vernonia School District is a public school district that serves students in the communities of Vernonia and Mist in the U.S. state of Oregon.  Vernonia Elementary School, Vernonia Middle School, and Vernonia High School are contained in separate wings of a single building in Vernonia constructed on high ground after floods in 1996 and 2007 severely impacted the city.  The new building was built above the floodplain to prevent future flooding. Vernonia High School is a public high school located in Vernonia, Oregon, United States.  In the wake of severe flooding in 2007, Vernonia City voters approved a $13 million bond in 2009 to build a new school complex in Vernonia.  The new school, now a K-12 school, was completed during the summer of 2012 at a cost $40 million.  The new building was built above the flood plain to prevent future flooding. Ulex (commonly known as gorse, furze or whin) is a genus of flowering plants in the family Fabaceae.  The genus comprises about 20 species of thorny evergreen shrubs in the subfamily Faboideae of the pea family Fabaceae.  The species are native to parts of western Europe and northwest Africa, with the majority of species in Iberia. 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. Vernolic acid (leukotoxin) is an organic compound and a fatty acid.  This monounsaturated long chain carboxylic acid contains an epoxide and consists of two optical isomers.  The (+) optical isomer's IUPAC designation is (+)-(12"S",13"R")-epoxy-"cis"-9-octadecenoic acid; it is also termed 12S,13R-EpOME, cis-12-epoxyoctadeca-cis-9-enoic acid, and (9"Z")-(12"S",13"R")-12,13-epoxyoctadecenoic acid.  The (-) isomer's IUPAC designation is (-)-(12"R",13"S")-epoxy-"cis"-9-octadecenoic acid; it is also termed 12R,13S-EpOME, cis-12-epoxyoctadeca-cis-9-enoic acid, and (9"Z")-(12"R",13"S")-12,13-epoxyoctadecenoic acid.  It is an isomer of coronaric acid, which is itself the (+) and (-), i.e. "R","S" and "S","R" optical isomers of 9,10-epoxy-12"Z"-octadecenoic acid (also termed 9(10)-EpOME and (+/-)-9(10)-epoxy-12Z-octadecenoic acid).  Vernolic acid was first definitively characterized in 1954.  It is the key component in vernonia oil, which is produced in abundance by the genera Vernonia and Euphorbia and is a potentially useful biofeedstock. The Banks–Vernonia State Trail is a paved rail trail and state park in northwest Oregon in the United States.  It runs for 21 mi , primarily north–south, between the towns of Vernonia in Columbia County and Banks in Washington County on an abandoned railroad bed.  Banks is about 25 mi west of Portland. 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. 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. Vernonia School District 47J v. Acton, 515 U.S. 646 (1997) was a U.S. Supreme Court decision which upheld the constitutionality of random drug testing regimen implemented by the local public schools in Vernonia, Oregon.  Under that regimen, student athletes were required to submit to random drug testing before being allowed to participate in sports.  During the season, 10% of all athletes were selected at random for testing.  The Supreme Court held that although the tests were searches under the Fourth Amendment, they were reasonable in light of the schools' interest in preventing teenage drug use. Vernonia Municipal Airport (FAA LID: 05S) is a city-owned, public-use airport located two nautical miles (3.7 km) west of the central business district of Vernonia, a city in Columbia County, Oregon, United States.
