Pycnanthemum monotrichum, commonly known as one-hair mountain-mint, is an extinct[1][2] species of herbaceous perennial plant in the family Lamiaceae endemic to Southeastern Virginia.[3] Pycnanthemum monotrichum inhabited dry, sandy woodlands and clearings in Virginia's coastal plain.[4] It is a poorly known taxon and may represent a hybrid, or a more abundant species that has been overlooked.[5][6] Pycnanthemum monotrichum bloomed from July through September and grew up to four feet tall.[7]
