[Ir., dark wooded headland (?)].
Forest, once standing in what is now Co. Sligo, mentioned prominently in Tóraigheacht Dhiarmada agus Ghráinne [The Pursuit of Diarmait and Gráinne]. Here Diarmait defeats the surly one-eyed giant Searbhán, who guards the magical quicken (rowan) tree which the Tuatha Dé Danann had brought with them from Tír Tairngire [the Land of Promise]. Gráinne desires the berries of the tree. While hiding in a tree in Dubros, Diarmait drops a berry on the board-game fidchell, allowing his friend Oisín to defeat Fionn mac Cumhaill.
