Yellowwood \Yel"low*wood`\, 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.
