Scientists have identified the new species of the tree, which is believed to have been lost before its name is even finished.
The tree, which has been called now Vapris BaliIt is believed that forest is unique to forest reserve in Africa, but it has destroyed the forest and destroyed it by agricultural development.
Scientists are studying commercial species for antimicrobial and antimelic properties of their essential oils.
Researchers hope that some other Trees will be known and that they will be named in Cameron before they disappear.
In 1951, a sample was collected by a forest, Edwin Ujour, in the Bali Nambiba Forest Reserve in Cameroon.
This specimen was considered genus vaporis, of which there are 80 species, which are mostly found throughout Africa. But the tree has not been seen anywhere since then.
Researchers from the Royal Botanical Gardens, Cave and the University of Yayond of the country examined the original and used molecular phylogenetic studies to identify new species.
They say that the tree is now critically endangered or extinct.
Between 2000 and 2004, repeated attempts to find species and at least six other studies failed to turn any sign that the tree still exists.
Thousands of species of plants face similar threats globally. According to the International Plant Name Index, only about 5% of known species have been formally assessed for their risk of extinction.
The authors wrote: "Priority seeks to find, document, and preserve these species before they become extinct globally."
Bali Nagemba Forest Reserve, officially protected forest, is part of the Bendanda Highlands, which is an area due to its natural herb vegetation, now known as "grasslands" in Cameroon.
Reserve reserves of up to 7,000 feet above sea level represents one of the last fossils of the Cloud forest and it is home to a unique collection of threatening plants, including at least 38 global plants.
But it is also being destroyed by expansion of human farmland.
Researchers said that if it was to stop now, "it is possible that the forest can be retrieved and national and global roles can continue in the preservation of species and natural habitat, even though some species have already been extinct globally".
