Comprising two distinct species, Quercus Alba (White Oak) and Quercus Virginiana (Southern Live Oak), Tihala, or Oak Trees, are an invasive species not native to the Planet Collena. The tree has a complicated history spanning nearly 400 years and has existed on Collena in some way since fifty years before the Exodus.
Earth plant biology is not the same as Collena biology which had lead to some interesting interactions with the biomes the trees are found in. Various campaigns over the last 300 years have been put in place to eradicate the trees from the face of the planet, but some nations, like Vefaria, actually quite like the tree, and has worked the bark and acorns into valuable products for export. The Tree doesn't actually cause any harm to the environment compared to the many other invasive species introduced to Collena over the years, but its different look from Collena plants creates an eyesore to some Regalti.
Etymology and Classification
The latin classification of the Oak goes without saying as it is established science and has been so for several hundred years on Earth. Oak trees are flowering plants that produce seeds and the Oak Tree genus (Quercus, Latin for Oak) comprises a large group of 500 species. The two invasive species of Oak on the planet are closely related to each other but on the Planet Collena, there aren't hardwood trees quite like this.
For the Regalti names, they call them Tihala. This derived is from the Cherokee word for Oak, "T'ala", who are the among the people responsible for Oaks on Collena and are where the original batch of acorns came from many hundreds of years ago.
