Tribe FuireneaeEdit

BolboschoenusEdit
 
Bolboschoenus fluviatilis
Bolboschoenus species are known as tuberous bulrushes or tuber-bulrushes. This genus has also been considered to be a section of Scirpus, which is similar but has spikelets that are usually smaller and more numerous.

  1. The New York Flora Atas states: "All studied vouchers reported as Fuirena squarrosa from New York sites have been annotated to Fuirena pumila." The USDA-NRCS PLANTS database, however, shows F. squarrosa present on Long Island, but no protected status is given for New York. Flora of North America also shows F. squarrosa present in N. Y.
SchoenoplectusEdit

Schoenoplectus (bulrush) has been separated from Scirpus due to phylogenetic differences.

The Schoenoplectus sections used here are from Flora of North America.
