We describe the correspondence between trees and seeds by showing that each tree grows from a unique seed and giving an algorithm to produce this seed. Using results about the structure of seeds, we enumerate the seeds of a given diameter.</p>}, number={2}, journal={Proyecciones (Antofagasta, On line)}, author={Johnson, Charles R. and Lettie, Jacob and Mack-Crane, Sander and Szabelska-Beręsewicz, Alicja}, year={2020}, month={Apr.}, pages={451-465} }
