Trees - or treelike beings - that can walk and speak. Huorns are powerful, wild, and dangerous. The origin of Huorns is somewhat mysterious. <link="proto:Meery">Merry Brandybuck</link> speculated that Huorns were Ents that had become more like trees. Treebeard also spoke of trees that had become Entish, so it is possible that some of these became Huorns as well. 

Huorns looked like trees, though they were strange in appearance, with twisted roots and long, grasping branches. They generally stood at rest, keeping watch over the ordinary trees. But when roused by a threat to the forest, Huorns could move swiftly and kill efficiently. It was difficult to see them move, for they seemed to be wrapped in shadow and they would appear as if out of nowhere. Huorns were able to speak with the Ents, and other people could hear the Huorns' voices murmuring through their branches.
