question: Which is native to North America, Comptonia or Caladium?
answer: Comptonia
context: Title: Theodore Luqueer Mead
  Passage: Theodore Luqueer Mead (February 23, 1852 – May 4, 1936) was an important American naturalist, entomologist and horticulturist.  As an entomologist he discovered more than 20 new species of North American butterflies and introduced the Florissant Fossil Beds in Colorado to the wider scientific world.  As a horticulturist, he is best known for his pioneering work on the growing and cross-breeding of orchids, and the creation of new forms of caladium, bromeliad, crinum, amaryllis and hemerocallis (daylily).  In addition he introduced many new semi-tropical plants, particularly palm varieties, into North America.  Recently a comprehensive historical biography of his life and times has been published.
  Title: Asaphidion
  Passage: Asaphidion is a Holarctic genus of ground beetle native to Europe, the Near East, North Africa, and North America.  Though predominantly a Palaearctic genus with one adventive exotic species in North America ("A. curtum" ), there are two native North American species in the genus: "A. alaskanum" and "A. yukonense" .  Both native taxa are Arctic in distribution, found mainly in tundra environments.  The introduced "A. curtum" is now found in the northeastern United States and adjacent Canadian maritime provinces.  These large-eyed, diurnal species are fast-running predators believed to be specialists on springtails and other tiny, soft-bodied prey.
  Title: Bighorn sheep
  Passage: The bighorn sheep ("Ovis canadensis") is a species of sheep native to North America named for its large horns.  These horns can weigh up to 30 lb , while the sheep themselves weigh up to 300 lb .  Recent genetic testing indicates three distinct subspecies of "Ovis canadensis", one of which is endangered: "O. c. sierrae".  Sheep originally crossed to North America over the Bering land bridge from Siberia; the population in North America peaked in the millions, and the bighorn sheep entered into the mythology of Native Americans. By 1900, the population had crashed to several thousand, due to diseases introduced through European livestock and overhunting.
  Title: Caladium
  Passage: Caladium is a genus of flowering plants in the family Araceae.  They are often known by the common name elephant ear (which they share with the closely related genera "Alocasia", "Colocasia", and "Xanthosoma"), Heart of Jesus, and Angel Wings.  There are over 1000 named cultivars of "Caladium bicolor" from the original South American plant.
  Title: Emerald ash borer
  Passage: Agrilus planipennis, commonly known as the emerald ash borer, is a green buprestid or jewel beetle native to northeastern Asia that feeds on ash species.  Females lay eggs in bark crevices on ash trees, and larvae feed underneath the bark of ash trees to emerge as adults in one to two years.  In its native range, it is typically found at low densities and does not cause significant damage to trees native to the area.  Outside its native range, it is an invasive species and is highly destructive to ash trees native to northwest Europe and North America.  Prior to being found in North America, very little was known about emerald ash borer in its native range; this has resulted in much of the research on its biology being focused in North America.  Local governments in North America are attempting to control it by monitoring its spread, diversifying tree species, insecticides, and biological control.
  Title: Comptonia (plant)
  Passage: Comptonia is a monotypic genus (containing only Comptonia peregrina) in the family Myricaceae, order Fagales.  It is native to eastern North America, from southern Quebec south to the extreme north of Georgia, and west to Minnesota.  The common name is sweetfern or sweet-fern, a confusing name as it is not a fern.
  Title: Indigenous music of North America
  Passage: Indigenous music of North America, which includes American Indian music or Native American music, is the music that is used, created or performed by Indigenous peoples of North America, including Native Americans in the United States and Aboriginal peoples in Canada, Indigenous peoples of Mexico, and other North American countries—especially traditional tribal music.  In addition to the traditional music of the Native American groups, there now exist pan-tribal and intertribal genres as well as distinct Native American subgenres of popular music including: rock, blues, hip hop, classical, film music, and reggae, as well as unique popular styles like waila ("chicken scratch").
  Title: Native Tour
  Passage: The Native Tour (also known as the Native Summer Tour in North America or Native Fall Tour in Europe) is the third headlining concert tour by American pop-rock band, OneRepublic in support of their third studio album, "Native" (2013).  OneRepublic were joined on the Native Summer leg of the tour by, The Script and American Authors, and on the European "Native Fall Tour" leg by Kongos.  The tour has traveled across five continents; Asia, Europe, Oceania, North America, and Africa.  The tour began on April 2, 2013, in Milan, Italy and finished on September 20, 2015, in São Paulo, Brazil.
  Title: List of Central American mammals
  Passage: This is a list of the native wild mammal species recorded in Central America.  Central America is usually defined as the southernmost extension of North America; however, from a biological standpoint it is useful to view it as a separate region of the Americas.  Central America is distinct from the remainder of North America in being a tropical region, part of the Neotropic ecozone, whose flora and fauna display a strong South American influence.  The rest of North America is mostly subtropical or temperate, belongs to the Nearctic ecozone, and has many fewer species of South American origin.
  Title: Cakile
  Passage: Cakile is a genus within the flowering plant family Brassicaceae.  Species in this genus are commonly known as searockets, though this name on its own is applied particularly to whatever member of the species is native or most common in the region concerned, the European searocket "Cakile maritima" in Europe, and the American searocket "C. edentula" in North America.  The genus is native to Europe, Asia and North America, but the European searocket has been introduced into North America and has spread widely on both east and west coasts; in many places it is replacing the native "C. edentula", and is regarded as an undesirable invasive species.
