The one had leaves of dark green that beneath were as shining silver, and from each of his countless flowers a dew of silver light was ever falling, and the earth beneath was dappled with the shadow of his fluttering leaves. The other bore leaves of a young green like the new-opened beech; their edges were of glittering gold. Flowers swung upon her branches in clusters of yellow flame, formed each to a glowing horn that spilled a golden rain upon the ground; and from the blossom of that tree there came forth warmth and a great light. Telperion the one was called in Valinor, and Silpion, and Ninquelótë, and many other names; but Laurelin the other was, and Malinalda, and Culúrien, and many names in song beside.
