  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.
Genus Schoenoplectus[edit]

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

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