Abstract

In recent years, most authorities on Cyperaceae have supported a narrow circumscription of Scirpus. To implement this approach, many new combinations are required and several of these are made here. Actinoscirpus is recognised as a monotypic genus, containing A. grossus comb. nov. It is argued that this genus is closely related to, but distinct from, both Bolboschoenus and Schoenoplectus in several respects. Bolboschoenus nobilis comb. nov. is separated from B. maritimus and a key is provided to distinguish the two. Scirpus beccarii is transferred to Isolepis. S. acaulis is transferred to Phylloscirpus and problems relating to this genus are briefly discussed. Finally it is suggested that Amphiscirpus should be retained as a genus, with its sole species A. nevadensis.
