Acer saccharinum
In Minnesota it is known from a limited number of locations in alluvial forest in the Cannon River Valley, where it was first found in 1976.. In Minnesota it grows in moist forests of "Ulmus americana", "Juglans nigra", and "Acer saccharinum". These forests often flood in the spring, with soils remaining saturated all growing season. In Minnesota, other uncommon species found in association with "Carex conjuncta" include "Carex davisii" and "Carex grayi".
