Aeglos (plant)
From Tolkien Gateway
Aeglos was a tall, thorny plant, similar to a gorse, but somewhat larger than that. Its sweet-smelling flowers were white, and from them it took its name: aeglos is Elvish for 'snow-thorn'. It was found on the slopes of Amon Rûdh in West Beleriand and surely elsewhere, but if it ever grew east of the Blue Mountains, it is no longer found today.
