Dotted Horsemint is an upright, smooth to hairy perennial.  Preferred habitat is rocky woods, sandy areas, swampy bottoms and stream banks. Distribution is throughout the Escambia region.

Leaves are opposite on the stem; consisting of one whole part; has leaf stalks; egg-shaped to lance-like in form; margins toothed and base is rounded to wedge-
shaped.  Leaf tip tapers to a long or short point.

The flowers are at the tip of a flowering stem, the heads subtended by numerous leafy bracts that may be pink or greenish-yellow.

Flower heads are spaced on the stem, each having a calyx that is symmetrical in form; corolla is pale yellow and spotted with purple; two stamens that extend beyond the corolla.

The related M. citriodora has pink or white flowers that are spotted with purple (see Purple Monarda, Summer Gallery).  Flowers occur in the summer and autumn.

Fruit is a schizocarp (an ovary with two or more seed chambers in which the seed chambers separate at maturity).
