This is meant to be a fun question, and I hope it's not too off topic. Is there a defined mathematical object or data structure that has a name collision with a type of physical tree in the real world?
In computer science we have red-black trees, B-trees, quadtrees, and so on. In the biological sense of the word tree, we have palm trees, pine trees, redwood trees, etc.
My question: is there a word $w$ such that a $w$ tree could refer to a physical tree in the real world, or a mathematical object?
