aka Listera cordata.The common name refers to the opposite pairs of leaves. The leaves, heart-shaped and up to 1 1/2″ long, are a distinguishing feature set opposite each other about half way up the stem which grows to 8″ (20 cm). Unlike most orchids the tiny flower’s lower lip is sharply divided into two elongated prongs with petals and sepals above creating an orchid that appears angelic. The flowers are normally green although there is a reddish-brown variety. Common is moist forests to 4,500′ elevation.
