Aquatic and Wetland Vascular Plants of the Northern Great Plains

41. Lamiaceae, the Mint Family

6. Stachys L. -- Hedge-nettle

2. Stachys tenuifolia Willd.

Similar to the preceding, 4-10 dm tall; stems glabrous or retrorsely bristled on the angles, the sides glabrous, bearded at the nodes. Leaves sessile or on petioles to 2 cm long, the blades ovate-lanceolate to oblong-lanceolate, 6-14 cm long, 2-6 cm wide, glabrous or with a few scattered hairs, acute to acuminate, serrate on the margins, rounded to cordate at the base. Calyx 5-7 mm long, usually with eglandular hairs only; corolla as in the preceding. Jun--Sep. Alluvial woods and stream banks; occasional from e ND to e NE; (NY to Man., s to SC, TN, LA and TX).

Some plants from e ND appear to have characteristics of S. palustris var. pilosa, i.e., having some glandular hairs intermixed with eglandular hairs on the calyces. Further studies on Stachys in e ND and w MN are needed to determine the true relationships of these populations.
