The status of variously described subspecies or varieties of Scirpoides holoschoenus is evaluated, with to the conclusion that only two subspecies should be recognized from the Azores to Turkestan and Punjab: S. holoschoenus subsp. holoschoenus and S. holoschoenus subsp. australis. Another subspecies occurs disjunctly in southern Africa: S. holoschoenus subsp. thunbergii. From the author’s field work in Sardinia, it emerges that only Scirpoides holoschoenus subsp. holoschoenus occurs in Sardinia. Cyperus badius is considered a species of its own, showing considerable and constant differences from C. longus. The latter was not found in Sardinia, while C. badius is widespread.
