Forum:Tribute 1 monster?

When we are looking through cards effect, it has been bothering me a lot lately.

My friend said that you can tribute anything on the field as long as it reads "Tribute 1 monster".

For example:

Dark Strike Fighter can tribute anything on the field because it only says "Tribute 1 monster on the field." But I find it irritating since it would destroy my flip monsters or the fact I have to destroy the card with Enishi's effect to chain the tribute effect. But I want to know if that is possible to do that.

Also Fragrance Storm says "Tribute 1 plant type monster on the field"

These rulings... are these right?
