There are so many Amazonian tree species, we won’t discover the last one for 300 years

In a new study, scientists have compiled data from museums around the world to find how many Amazonian tree species have been described so far. The answer: 11,676. They also estimate that there are another 4,000 species yet to be discovered, and it will take 300 years to find them all. The report includes a checklist of all known Amazonian trees for conservation ecologists to use in their work.
