Concept Reference: Kartesz, J.T. 1994. A synonymized checklist of the vascular flora of the United States, Canada, and Greenland. 2nd edition. 2 vols. Timber Press, Portland, OR.
Concept Reference Code: B94KAR01HQUS
Name Used in Concept Reference: Carex flava
Taxonomic Comments: As treated by Kartesz (1999), the species Carex flava is accepted without subspecies or varieties. Of the several varieties sometimes recognized in Carex flava, five (vars. fertilis, gaspensis, graminis, laxior, and rectirostra) are included in the synonymy of C. flava. However, vars. lepidocarpa and nelmesiana are included in Carex virida, and part of var. fertilis is included in C. cryptolepis. LEM 6Jun00.
