Arctophila fulva (Trin.) Andersson
Annotated by Carolyn Parker. Remarks: The best match was with the ligules on the lowermost part of the stems, still in water or recently emerged. On upper stem ligules are modified on the aerial stem sections. The other closest match was Koeleria asiatica, but there was no hint of stem and leaf hairs on your specimens, and material has well developed rhizomes.
