2n=36, 28, 40, 42 (Moss, 1983). Also called Ophyrus cordata(Moss, 1983). This is the most common species in Listera but is still quite rare (Johnson et al., 1995). Its pollination strategy interested Charles Darwin; pollen is explosively expelled in a drop of fluid that glues pollinia to insects (Johnson et al., 1995(.
Range/Distribution Alberta: SW in mountain range to central (Canadensys). CAN (BC, MB, NB, NL, NS, SK, NT, ON, PE, QC, YT); USA (AK, WA, OR, CA, MT, ID, NV, WY, UT, CO, NM, MN, WI, MI, VA, OH, NY, ME, WV, PA, NJ, CT, RI, VT, NH, MA) (USDA).
