There isn't one. In the Throne Road, look toward the south near the Village. Inside the village, the tree is in the SE near the Cockatrice pen. Toam Hills has one near the SE corner, near the Ichthons. In Starfall Field, check the NE corner, right by the entrance to the zone. In the Crystal Glade it’s across from the dark stone. And finally, go to the north of North Bank, along the eastern edge.
