In FRPS (8: 15. 1992), Pandanus urophyllus was treated as a synonym of P. furcatus Roxburgh. We follow Stone (Fl. Cambodge, Laos & Vietnam 20: 34-35. 1983) in maintaining P. urophyllus as a distinct species.

The leaves are used to make raincoats. The roots are used medicinally (FRPS 8: 15. 1992), but details are lacking.
