Shorter, sturdy raceme of 4 to 18 green to white flowers, each about ¼ inch across and ½ inch long. An upper sepal and 2 petals loosely form a hood above the creamy colored pollen sacs, 2 larger broad lateral sepals sweep out and back on sides. The long narrow lower lip is sharply tapered below; the spur behind the flower is of similar shape and size. This flower typically displays with upper hood projected straight out horizontally, lower sepals and lip projecting down and back.
Usually 1, rarely 2 basal leaves 1½ to 6 inches long, ½ to ¾ inch wide, typically broadest above the middle, with a blunt or rounded tip and tapering at the base. The stem is smooth, usually without bract-like leaves that are found on many other Platanthera species, but rarely has 1 on the upper stem.
Fruit is an erect capsule about 3/8 inch long containing many seeds, that ripens to brown in late summer. They can persist until the following season.
