Calamites (SciiFii)

The yggdrasil (Calamites vulgaris) is a species of arborescent (tree-like) horsetail to which the horsetails (genus Equisetum) are closely related. The yggdrasil originally lived during the Carboniferous Period as an extinct species of Calamites and the genus itself was once extinct, but has since been brought back from extinction by SciiFii due to demand for more exotic flora for their gardens, although some of the yggdrasils have been found growing and spreading in the rainforests and wetlands across the modern southeastern United States, Southeast Asia, and parts ot Australia. Unlike their herbaceous cousins, the yggdrasils are medium-sized tree-like plants, growing to heights of 30-50 meters (100-160 feet). These plants cover large areas by the means of underground rhizomes that frequently sprouts new yggdrasils. Their growth is extremely fast, with the individual yggdrasils reaching full size in just a decade and then being replaced by new ones. It is unknown if this is natural or if the growth rate was accelerated by genetic tampering with a species of bamboo. The yggdrasils cannot tolerate extremely cold temperatures or dry conditions, and need to have their roots constantly waterlogged, which prevents their spread into arid areas. The average lifespan of the yggdrasils are around 10 years. The yggdrasil's hollow wood is used by sapient species to create a unique, musical instrument called the torparn. The fresh yggdrasil sprouts can be cooked and eaten, but are mildly toxic to many animals if not prepared properly. Although the yggdrasils have almost no natural predators, a few species are able to feast on the yggdrasils with no ill effects, such as stegodonts, orangutans, ceratopsians, and ornithopods. The conservation status of the yggdrasil is Least Concern due to successful conservation efforts, the yggdrasil's wide range and its tolerance to many of the human activities.
