Wetland indicator: OBL

Although slender, the stems of this species are more stout than L. nuttallii or L. kalmii. It also differs from those two species in that the lower lip of the corolla is glabrous within rather than bearded. Another similar and rare species is L. boykinii which has glabrous pedicels (vs. scabrous) and lacks bracteoles at the base of the perdicels.
