Perhaps some of you more scientific type out there can answer this question:

What makes a "pure species?"

I often read about "natural" hybrids. These plants are hybrids of plants
that are often found together. How do you know that the natural hybrid
isn't a pure species?

Suppose you are out walking through the jungle and you find three plants.
What makes you say to yourself "Hey! Wow! Look at this, two pure species
and one natural hybrid!"
