Pogogyne nudiuscula
Also called Otay Mesa Mint
Otay mesa mint is a rare annual herb in the mint family, found only in vernal pools on Otay Mesa in southern San Diego County, California, and nearby northern Baja California. It is federally listed as endangered, so it should not be collected from the wild; growing it requires seed from conservation sources and a seasonally wet, sunny spot.
Pogogyne nudiuscula is a rare species of flowering plant in the mint family known by the common name Otay mesa mint. It is native to southern San Diego County, California, where it is known only from Otay Mesa near the border with Baja California. It was identified on land south of the Mexican border, but these occurrences have probably been extirpated. It is now known from seven vernal pool complexes just north of the border, and it is a federally listed endangered species of the United States.
This annual herb produces an erect stem 9–30 cm (3.5–11.8 in) in height. Its herbage is strongly aromatic and coated very thinly with straight, bristle-like hairs, or no hair. The inflorescence, 10–20 mm (0.39–0.79 in) wide, consists of interrupted clusters of opposite cymes. The bracts are green with acute tips.
