Habenaria clavellata of Michigan Flora.

An inconspicuous yellow-green orchid in bogs (open mats to older cedar or tamarack swamps) and coniferous forests, red maple swamps, mossy stream banks, boggy beach pools and shore meadows; often thriving along roadside ditches and in shallow sandy excavations, in acidic soils.

Locally frequent, but easily overlooked. See under Platanthera blephariglottis for comments about Platanthera × vossii Case.
