|“||Silver flow the streams from Celos to Erui
In the green fields of Lebennin!
Tall grows the grass there. In the wind from the Sea
The white lilies sway,
And the golden bells are shaken of mallos and alfirin
In the green fields of Lebennin,
In the wind from the Sea!
–Legolas, The Last Debate, The Return of the King
Mallos is a type of flower found in some of the coastal areas of Gondor.
The name is Sindarin in origin and means 'golden flower'.
