Blechnum serrulatum is perhaps the most widely distributed species of Blechnum, occurring from S Florida and the Antilles to NE Argentina, Malaysia, New Caledonia, and Australia. In the New World, this is the only species of Blechnum with articulations between the pinnae and the rachis (see photos).
