TYPIFICATION OF SOME LINNAEAN NAMES IN PHALARIS (GRAMINEAE)

Lectotypes are designated or confirmed for the names of 6 Linnaean Phalaris species, plus one variety. Traditional usage is maintained in all cases. P. aquatica L. (syn. P. tuberosa L., P. bulbosa auct.) cannot be rejected as a nomen confusum, a category of name that no longer exists. P. bulbosa L. is kept in synonymy under Phleum subulatum (Savi) Ascherson & Graebner, also lectotypified here. The type of Phalaris arundinacea L. belongs to the widespread tetraploid cytotype. The hexaploid bears the name P. arundinacea subsp. oehleri Pilger (holotype verified) of which P. caesia Nees, here lectotypified, is a synonym.
