Lemonwood, not the wood of the lemon tree, but so called because of its pleasant citrus smell when felled. More popular than boxwood because of cost, lemonwood is an excellent engraving surface. Lemonwood is pale straw in colour and very even in density. It comes in larger sections than boxwood making it easier to construct large blocks.
Calycophyllum candidissimum, Degame.Although sometimes called Castello Boxwood, this is not of the Buxus genus. It shares many of the properties of true boxwood, though not quite as dense.
