Kim giao is the Vietnamese name for a coniferous tree, with the botanical names Podocarpus fleuryi and Nageia fleuryi. The Vietnamese name is derived from the protagonists in a Vietnamese love story about a boy named Kim and a girl called Giao. Since the boy was poor he could not raise the money needed for the dowry to marry his beloved, and both died of a broken heart. Where their bodies lay, a Podocarpus Tree (fig.) emerged, which was named kim giao accordingly.
