ABOUT FAMILY (Weakley Flora)
Cyperaceae A.L. de Jussieu 1789 (Sedge Family)
SUMMARY: A family of about 100 genera and 5000 species, mostly herbs, cosmopolitan.
REFERENCE: Ball, Reznicek, & Murray in FNA (2002b); Muasya et al. (2009); Tucker (1987); Goetghebeur in Kubitzki (1998b).
ABOUT GENUS (Weakley Flora)
Schoenoplectus (Reichenbach) Palla 1888 (Bulrush)
SUMMARY: A genus of about 50 species, herbs, cosmopolitan in distribution. Micromorphologic, anatomic, and molecular studies have confirmed earlier opinions based on morphology that Schoenoplectus is not closely related to Scirpus (Strong 1994, Smith 1995, Schuyler, pers. comm.). Most investigators now also favor the separation of Bolboschoenus from Schoenoplectus (Pignotti & Mariotti 2004).
REFERENCE: Strong (1994)=Z; Smith (1995)=Y; Smith in FNA (2002b); Shiels et al. (2014); Goetghebeur in Kubitzki (1998b); Pignotti & Mariotti (2004). [also see Bolboschoenus and Schoenoplectiella]
