The maple seeds (or keys) in the photo at left belong to the species of maple called box elder, a few of which grow along the lake trail. Norman Smith calls box elder a "poor relation of the maples, which has little in common with them except the seeds and sap." Box elder's seeds hang in the "dense drooping clusters" characteristic of maple wings, but differ from them in the sharp angle or conspicuous V-shape of the wings (152).
