question: Which is a type of grass, Uniola or Corymbia?
answer: Uniola
context: Title: Uniola condensata
  Passage: Uniola condensata is a species of grass in the Poaceae family.
  Title: Echinochloa crus-galli
  Passage: Echinochloa crus-galli is a type of wild grass originating from tropical Asia that was formerly classified as a type of panicum grass.  It is commonly known as cockspur (or cockspur grass), barnyard millet, Japanese millet, water grass, common barnyard grass, or simply "barnyard grass" (which may refer to any species of "Echinochloa" or the genus as a whole however).  This plant can grow to 60" (1.5 m) in height and has long, flat leaves which are often purplish at the base.  Most stems are upright, but some will spread out over the ground.  Stems are flattened at the base.  The seed heads are a distinctive feature, often purplish, with large millet-like seeds in crowded spikelets.
  Title: Chasmanthium latifolium
  Passage: Chasmanthium latifolium, known as woodoats, inland sea oats, northern sea oats, and river oats is a grass native to the central and eastern United States, Manitoba, and northeastern Mexico; it grows as far north as Pennsylvania and Michigan, where it is a threatened species.  The species was previously classified as "Uniola latifolia" (André Michaux).
  Title: Corymbia
  Passage: Corymbia is a genus of about 113 species of tree that were classified as "Eucalyptus" species until the mid-1990s.  It includes the bloodwoods, ghost gums and spotted gums.  The bloodwoods had been recognised as a distinct group within the large and diverse "Eucalyptus" genus since 1867.  Molecular research in the 1990s, however, showed that they, along with the rest of the Corymbia section, are more closely related to "Angophora" than to "Eucalyptus", and are probably best regarded as a separate genus.  All three genera—"Angophora", "Corymbia" and "Eucalyptus"—are closely related, often difficult to tell apart, and are still commonly and correctly referred to as "eucalypts".  Groups of naturalists and conservationists do not recognise the "Corymbia" genus and still categorise its species within "Eucalyptus".
  Title: Uniola paniculata
  Passage: Uniola paniculata or sea oats, also known as seaside oats, araña, and arroz de costa, is a tall subtropical grass that is an important component of coastal sand dune and beach plant communities in the southeastern United States, eastern Mexico and some Caribbean islands.  Its large seed heads that turn golden brown in late summer give the plant its common name.  Its tall leaves trap wind-blown sand and promote sand dune growth, while its deep roots and extensive rhizomes act to stabilize them, so the plant helps protect beaches and property from damage due to high winds, storm surges and tides.  It also provides food and habitat for birds, small animals and insects.
  Title: Corymbia opaca
  Passage: Corymbia opaca, also known as the Desert Bloodwood, is a tree native to Australia.  The tree is most well known for the distinctive red kino that it exudes.  Australian Aboriginal people collect bush coconuts (a type of bush tucker) from the tree, which are produced by an insect in gall.
  Title: Boletus austroedulis
  Passage: Boletus austroedulis is a species of bolete fungus in the family Boletaceae.  Described as new to science in 2014, it is found in Australia, where it grows in groups on the ground under pink bloodwood ("Corymbia intermedia") and rose she-oak ("Allocasuarina torulosa").  It is thought to be the first member of "Boletus" section "Boletus" (commonly known as the porcini) that is endemic to Australia.  Although "Boletus edulis" has previously been reported from the continent, it is always in association with introduced trees, suggesting that itself is also introduced.  The type collection was made in Davies Creek National Park in Queensland.
  Title: Uniola
  Passage: Uniola is a genus of New World plants in the grass family.
  Title: Foxtail (diaspore)
  Passage: A foxtail is a spikelet or cluster of a grass, that serves to disperse its seeds as a unit.  Thus, the foxtail is a type of diaspore or plant dispersal unit.  Some grasses that produce a foxtail are themselves called "foxtail", also "spear grass".  They can become a health hazard for dogs and other domestic animals, and a nuisance for people.  Foxtail Grass is most commonly found in the Great Plains where bison and other native animals graze on it.  Fires started by lightning can burn down Foxtail Grass, but the grass has roots underground that allow it to grow back.
  Title: Protoxerula
  Passage: Protoxerula is a fungal genus in the family Physalacriaceae.  Described in 2010 by American mycologist Ron Petersen, the genus is monotypic, containing the sole species Protoxerula flavo-olivacea.  This species was originally described as a "Xerula" in 2008 and transferred to "Oudemansiella" the following year before the new genus was circumscribed to accommodate it.  "P. flavo-olivacea" is known from northeastern Australia, where it fruits singly to scattered in undisturbed rainforest, usually near plants from the genera "Acacia", "Agathis", and "Corymbia".  The variety "kimberleyana", named for its type locality in the Kimberley Region of Western Australia, has a greenish-cream cap colour, gills that become white and readily crumble when dry, long pseudorhiza (a cordlike structure resembling a plant root) with a hairy surface, ellipsoid basidiospores, thick-walled "hairs" (setae) on the cap surface, and a unique capitulate ("head-like") pleurocystidia.
