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
Boreal bedstraw is a native bedstraw with a disjunct distribution that includes northeastern and northwestern North America. It is very rare in New England, with a few populations each from Maine, New Hampshire and Vermont in boreal and subalpine forests, seeps and stream banks, often associated with bryophytes.

- corolla cream-white, schizocarp glabrous or with hairs that are not hooked at the apex, and leaf blades 1-2.5 mm wide (vs. G. kamtschaticum, with the corolla yellow-white, schizocarp with uncinate bristles, and leaf blades mostly 5-25 mm wide).
