The sedge, Carex platyphylla, is one of 67 species in this genus known from the George Washington Memorial Parkway

The sedges (Cyperaceae) make up one of the the most diverse groups of vascular plants within the George Washington Memorial Parkway (GWMP). Currently, 94 species in eight genera are known to be extant within GWMP and five additional species are known from historic specimen records. Undoubtedly, even more will be discovered as future inventory efforts increase. As recently as 2003 a species of native sedge new to the State of Virginia (Carex davisii), was found within GWMP.

Additionally, the rushes and wood rushes (Juncaceae) are represented by eight species within GWMP.
