Notes: Stachys palustris (hairy hedge nettle) is a perennial, 15-80 tall; stems are usually several, with spreading or downward-pointing hairs, especially on the angles, sometimes also with glandular hairs; leaves are lance- triangular, lance-ovate, or elliptic, 2-9 cm long, margins crenate; blades are sessile; inflorescence is a series of verticils arising in the axils of leaves to progressively reduced bracts; corolla is 8-15 mm long, pale rose or lavender, often mottled with purple or white. It typically occurs along streams, lakeshores, and other moist habitats at 2100-3000 m (7000-10000 ft). Two additional species of Stachys may occur in our area but are generally uncommon. Stachys coccinea (scarlet hedgenettle) is distinguished by its petiolate leaves and bright red corolla. It is mostly found south of our range, but has been collected in the White Mountains of Apache County. Stachys crenata (mousesear), which has been reported in the White Mountains of Apache and Navajo counties, is distinguished by its small flowers, the corolla up to 4 mm long. The Navajo use S. rothrockii as a foot deodorant.
