New England distribution
Adapted from BONAP data
Native: indigenous.
Non-native: introduced (intentionally or unintentionally); has become naturalized.
County documented: documented to exist in the county by evidence (herbarium specimen, photograph). Also covers those considered historical (not seen in 20 years).
State documented: documented to exist in the state, but not documented to a county within the state. Also covers those considered historical (not seen in 20 years).
Note: when native and non-native populations both exist in a county, only native status is shown on the map.

Facts
Teel lovegrass is native to New England, though it is very rare in the northern part of its range. It inhabits sandy, silty and muddy shores. It's one of a very few lovegrass species that has long, creeping stolons that root at the nodes; thus, it can form mats. Its panicles of long, ovate spikelets are handsome.
Habitat
Floodplain (river or stream floodplains), shores of rivers or lakes
