Hi there,

While the overall leaf shape you saw was similar, the details are super important when you are trying to identify a species. Think about dogs and cats: they both have 4 legs, furry ears, tails, bodies covered with fur, but they are NOT the same species.

Check out the edges of the leaves you saw and compare again with your identification page. What's the same? what's different?

cheers,
