Leaves Usually below middle of stem; egg to kidney-shaped; heart-shaped at base; 1-4 cm long (Moss, 1983). Opposite (Johnson et al., 1995). Flowers Purplish to yellowish-green; sepals and petals egg-shaped; 2-3 mm long; lip 2-4 times longer than wide, 4-5 mm long; cleft below middle into lobes; 2 teeth near base (Moss, 1983). 5-16 in cluster (Johnson et al., 1995).

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(.
