Mallos is the name of a small, but beautiful flower. According to J.R.R. Tolkien, the elf Legolas sang the following words about this flower and the place where it grows:
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!
