Family, Orchis. Colors, greenish, yellowish brown, white, and crimson. Sepals, narrow, greenish yellow, with a purple tinge. Petals, yellowish, purplish above, like the sepals in form, arching over the column. Lip, white, with magenta spots, open, spreading, shorter than the petals. Leaf, 1, petioled, but not sheathing at the base, springing from the bulbous root at the side of the scape, large, oval, pointed, 4 to 6 inches long. Flowers, about 10, in loose racemes, each upon a separate pedicel and with a narrow bract underneath. May and June.

The singular, united corms of this plant give it its marital name, 2, sometimes 3 or 4, being joined by offshoots. One new bulb is formed every year, but retains life for 2 or 3 years. The latest corm sends up, late in summer, a broad-plaited, many-nerved leaf, which usually lasts over the winter. The next season the flowers come up. Rich, moist woods, extending over the country from New England to California southward to Missouri.
