Which is a type of grass, Uniola or Corymbia?
Corymbia 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".
Tuctoria Tuctoria is a genus of three species of grass in the family Poaceae. Spiralgrass is a common name for plants in this genus. These are bunchgrass species that are found in vernal pools of central California and Baja California, Mexico. The plants are annuals that germinate under water in the spring and grow submerged for weeks. After the pools dry down, the grasses initiate a new set of foliage that lasts for one to two months until flowering and fruiting are complete.
