Beechbone

Beechbone was the name, at least according to Peregrin Took, of a notably tall and handsome Ent. He was caught in a burning spray sent up by Saruman from the beneath the Ring of Isengard, but his fiery end brought his fellow Ents to the peak of their destructive anger.

Portrayal in Adaptions

In Peter Jackson's The Two Towers there is an Ent that survives being set alight by extinguishing the flames in the floods of the River Isen. However it is not named, nor has any dialogue
