Which is a type of grass, Uniola or Corymbia?
Uniola Uniola is a genus of New World plants in the grass family.
Scytonema Scytonema is a genus of photosynthetic cyanobacteria that contains over 100 species. It grows in filaments that form dark mats. Many species are aquatic and are either free-floating or grow attached to a submerged substrate, while others species grow on terrestrial rocks, wood, soil, or plants. "Scytonema" is a nitrogen fixer, and can provide fixed nitrogen to the leaves of plants on which it is growing. Some species of "Scytonema" form a symbiotic relationship with fungi to produce a lichen.
