Leersia oryzoides (L.) Sw.
Common Name: CUT GRASS
Coefficient of Conservatism: 3
Coefficient of Wetness: -5
Wetness Index: OBL
Physiognomy: Nt P-Grass

Wet places: ponds, shores, ditches, floodplains, stream and river banks, bogs, pools and wet depressions, often abundant in a distinct zone or band.

A grass with very rough foliage and spikelets, the latter readily adhering to clothing when ripe, much to the annoyance of hikers in moist places where it grows. The margins of the leaf blades are normally roughly hispid-ciliate in this species (rarely only scabrous), while in L. virginica they are merely scabrous (rarely with a few rough cilia on some leaves). In both species, the nodes are characteristically bearded with ± retrorse hairs. At least the base of the inflorescence is often hidden by the upper leaf sheath; spikelets developing within leaf sheaths seem more often to produce mature grains than do those of exposed terminal panicles. Rare intermediates with L. virginica are known from Michigan, suggesting hybridization.
