You're likely thinking of trees with helicopter seeds, also known as samaras. These seeds have a wing-like structure that allows them to spin and flutter as they fall, extending their dispersal distance.

Here are some common trees with helicopter seeds:

* Maple trees: Many maple species have distinctive helicopter seeds, including sugar maple, red maple, and Norway maple.

* Ash trees: Ash trees also produce samaras, though they are narrower and more elongated than maple seeds.

* Elm trees: Elms have flat, oval-shaped samaras that can be quite large.

* Birch trees: While not as commonly known, some birch species, like the paper birch, produce small, winged seeds that spin as they fall.

It's worth noting that not all trees with winged seeds produce spinning seeds. Some have larger wings that help them glide, but don't spin.
