Discussion

Although Luzula hitchcockii has been reported from California, no convincing specimens have been seen by this author. The species resembles the European L. glabrata (Hoppe) Desvaux very closely; however, it is readily distinguished from all other North American species. Plants may be heavily infested with Ustilago vuijckii Oudemans. and Beijerinck. complete last names??, which considerably alters their usual appearance.
