  Lamiaceae Mentha canadensis
Photographed 14 February 2015.

Coll. No. 1032.1, 24 Jul 2013, characters observed while keying: Perennial herb, to 30 cm., spreading by rhizomes; Stem, erect, 4-angles, hairy; Leaves, opposite, ±equal in size, ovate, 37 mm. × 15 mm. wide, margins serrate, surfaces nearly hairless; Petiole 4.5 mm.; Inflorescence axillary, bract margin hairy; Calyx, lobes 5, short hairy outside; Corolla 5 mm.; Stamens 4, exserted.

Some characters, such as ovate and near-glabrous leaves, suggest M. arvensis, whereas a short-hairy calyx and 5 mm. corolla suggest M. canadensis.

While the TJM2 description says, “bracts minute or 0,” the bracts shown here are 3 mm.
