Quebracho
The encyclopedia referred to this tree as an “axe breaker,” because apparently it is a very hard barked tree. However, wikipedia and brittancia.com did not mention the nickname “axe breaker.” All of the sources confirmed that these trees grow in the Gran Chaco area of South America. I find that looking up stuff on the Internet is way more beneficial, and less time consuming. Wikipedia is a more useful cite, the content is more accessible and easier to read. Britannica was annoying, because a pop-up kept blocking what I was trying to read. They actually want you to buy a membership. Encyclopedias are also expensive, and I much rather prefer free.
