yellowroot

n. (Bot.) The wood of any one of several different kinds of trees; also, any one of the trees themselves. Among the trees so called are the Cladrastis tinctoria, an American leguminous tree; the several species of prickly ash (Xanthoxylum); the Australian Flindersia Oxleyana, a tree related to the mahogany; certain South African species of Podocarpus, trees related to the yew; the East Indian Podocarpus latifolia; and the true satinwood (Chloroxylon Swietenia). All these Old World trees furnish valuable timber. [ 1913 Webster ]
