A huge Elven tree that grew in Tol Eressëa, Númenor and in Lothlórien. Mallorn (pl. mellyrn) is the Sindarin name of the plant, its Quenya equivalent being malinornë; both mean 'golden tree' and refer to the leaves' colour in autumn and winter.The tree is most fully described in Unfinished Tales:
“ Its bark was silver and smooth, and its boughs somewhat upswept after the manner of the beech; but it never grew save with a single trunk. Its leaves, like those of the beech but greater, were pale green above and beneath were silver, glistering in the sun; in the autumn they did not fall, but turned to pale gold. In the spring it bore golden blossom in clusters like a cherry, which bloomed on during the summer; and as soon as the flowers opened the leaves fell, so that through spring and summer a grove of malinorni was carpeted and roofed with gold, but its pillars were of grey silver. Its fruit was a nut with a silver shale.
