Why was I hesitant? It has to do with the genus of plants. The third plant I found that day was a sedge or Carex species. Michiganflora list 184 Carx species found in the state of Michigan and they are notoriously difficult to identify. However, I was able to narrow the list of possibles down significantly by looking at habitat. There are 103 obligate wetland or facultative wetland species of sedge found in Michigan; obligate wetland species are almost always found in wetlands and facultative wetland species are usually found there. This left only 81 likely possibilities.
After eliminating species that are found only in a few locations, as well as those species that looked completely wrong, I was able to come away with an identification.
