The Bibliotheca (3.15.1) states that the legendary Erechtheus' wife Praxithea was the daughter of Phrasimus (otherwise unknown to us) by Diogenia (otherwise unknown to us) daughter of Cephissus.

The source of the river is in the saddle depression between the Parnitha and Penteli mountains. From there it flows generally southwest until it reaches the Phaleron Bay between Neo Faliro and Moschato. Presently the river flows near or under the A1 motorway, linking Athens and Thessaloniki for much of its length. This section of the A1 is named Avenue Kifissou, near which is the Kifissos Bus Terminal.
