Synandra is a monotypic genus of flowering plants in the mint family containing the single species Synandra hispidula, which is known by the common name Guyandotte beauty. It is native to the east-central United States where it ranges from southern Illinois to western North Carolina and Virginia.

==Description== This species has been reported to be an annual, biennial, or perennial herb, but studies show that it is a "strict biennial", at least in Kentucky and some populations in Ohio. It has oppositely arranged leaves with serrated edges. The large yellow and white or pinkish flowers bloom in April through June. The flowers are over 2 centimeters long and may reach 4 centimeters. Plants can have up to eight multiple branches on a single individual. Nutlets usually weight around 7 mg, with weights up to 13 mg. The nutlets store a high amount of endosperm.
