Cyperaceae such as Cyperus compressus, C. elegans, Scirpus sp.
Seven major grassland types have been identified, which consitute about 20% of the park's area: Themeda villosa forms a tall grass cover in clearings in the sal forest; Saccharum-Narenga associations grow as mixed and pure stands of tall grass (Saccharum spontaneum is one of the first species to colonize newly created sandbanks); Arundo-Phragmites associations form dense tall stands along stream beds on the floodplain and around lakes; Imperata cylindrica grows prolificallyin areas within the park which were occupied by villages prior to their evacuation in 1964; various short grasses and herbs grown on exposed sandbanks during the dry months and become much more prolific with the outset of rain in May (e.g. Polygonum plebeium, Persicaria spp. and sedges such as Cyperus, Kyllinga and Mariscus spp.); Cynodon dactylon and Chrysopogon aciculatus and other short grasses grow in highest areas near riverine forest all the year round; and low-lying stands of Saccharum spontaneum, which are destroyed by repeated flooding early in the monsoon.
They are dominated by Cyperus latifolius with C. aterrimus or Hypericum lanceolatum, Alchemilla cryptantha, Anagallis angustiloba and Jussiaea repens.

Domingensis (totoras) and the beautiful blue-flowered pontederiacea Pontederia lanceolata (cucharero).
