Malaxis bayardii (Bayard's adder's-mouth orchid)[2] is a species of orchid native to northeastern North America. It is found from Massachusetts to North Carolina, with isolated populations in Ohio and Nova Scotia.[3] There are historical reports of the plant formerly growing in Vermont and New Jersey, but it seems to have been extirpated in those two states[1] It grows in dry, open woods and pine barrens at elevations of less than 600 m (2000 feet).[4][5]

Malaxis bayardii is a terrestrial herb up to 26 cm (10.4 inches) tall. It produces a pseudobulb up to 20 mm in diameter. It generally has only one leaf, occasionally two, about half way up the stem. Flowers are small and green, borne in a raceme of up to 70 flowers.[6][7][8][9]
