Why do you need to identify these leaves? Is this a plant growing in your garden? Are you taking part in a plant ID competition? Have you been set this Id problem as homework?
I agree with the requests for more information ... however my first instinct is that they are quite like pelargonium leaves, possibly one of the trailing types.
