The Gwingyrn (S. "spindrift-Trees") were enchanted Trees, which Osse first gave as a gift to Cirdan the Shipwright in Beleriand. These were the trees which the Falathrim felled solely for the purpose of building their beautiful swan-ships. The gwingorn was so-called not only because of its association with the sea and shipbuilding, but also because in the springtime it bursted forth with great clusters of tiny white blossoms that resembled the foam flying off of crested waves. Gwingyrn were evergreens and their silvery minks grew to a height of up to a hundred feel; their leaves were broad and five-pointed, and were often used for making garlands.
