We consider EOL grammars as tree generating mechanisms. This leads to questions of height, weight, and structural equivalence of EOL grammars. Height equivalence is solved completely, weight equivalence remains open, and structural equivalence is solved for three special cases. We characterize those EOL grammars which generate exactly the set of 2,3-trees.
