Botany: double-toothed leaf
Self-tutoring about tree identification: the tutor looks into the meaning of double-toothed leaf.
Often in my reading a tree’s leaves are described as double-toothed – meaning what?
Single-toothed simply means the edge of the leaf is like a saw blade as opposed to smooth. Double-toothed means there is a second level that is less pronounced: each main tooth hosts a minor one.
