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.

   xy`lon wood.] (Bot.)

   of which are of a deep yellow color; prickly ash.
