American Pennyroyal. Hedeoma pulegioides. 



Found, from July to September, in upland fields and pastures. 



The sometimes branching stalk is slender, but strong in fibre ; it 

 grows from 5 to 10 inches high, and is hairy to the touch. Green 

 in color. 



The small leaf is long-pointed, with a slightly toothed margin, and 

 somewhat roughened surface. It is medium green in color. The leaves, 

 on slight stems, are set in pairs, which occur closely, and at right angles 

 to each other. 



The corolla of the very small flower consists of a downy 2-lipped 

 tube, the upper lip being largest, flat, and notched at the tip, the lower 

 3-cleft; it is lavender in color. The small calyx is 5-parted. The 

 flowers are set, on tiny stems, in rings about the stalk in the angles of 

 the leaves, forming a terminal spine. 



The perfume of the Pennyroyal is carried to a considerable distance, 

 — were it not for this aromatic pungency the casual observer would 

 often fail to find its haunt, so closely does it keep itself among the 

 grasses of the pasture.
