贍部樹者，起世云：於此樹下，有閻浮檀那金，聚高二十由旬，以此勝金，出閻浮樹下，是故從樹為名，一切閻浮檀金從此得名。設拉末梨，似皁筴樹，此所無也。

As for the "jambu tree": the Qishi jing states: Beneath this tree is Jambūnada gold, piled twenty yojanas high; because this superior gold emerges beneath the jambu tree, it is named after the tree, and all Jambūnada gold derives its name from this. The śālmali resembles the honey locust tree, and does not exist here.
