Abstract
New Zealand and South American species of Griselinia are compared with other genera of the Cornaceae, Araliaceae, and Escalloniacea. The main features examined are the morphology and anatomy of the shoot, the anatomy of the secondary xylem, and the vasculature of the flower. While Griselinia resembles all these families in some respects it does not fit within the boundaries of any one family. The implications of the complex inter-relationships between these and other families are discussed, and it is concluded that the evidence at present available gives little support to the retention of Griselinia in the same family as Cornus, though it is insufficient to settle the problem of its placement in any existing family.
