What is the poem wrote by Fernando maria Guerrero?

There seems to be a misunderstanding. Fernando María Guerrero is a Spanish writer and journalist, but he is not known for writing poems.

Perhaps you are thinking of a different author? Could you provide more context or details about the poem you are looking for? For example:
