Not totally straighforward. All the info is in DBA_CONSTRAINTS. First you must find the name of constraints of type 'P' (primary key) or 'U' (unique, can also be referenced by a foreign key) associated with your table, then (auto-join), the name of tables having a constraint of type 'R' referencing this type 'P' or 'U' constraint. There is alos a script named desc8.sql on the Oriole site which is (basically) an improved version of the 'desc' SQL*Plus command and shows, among other things, this type of info.
