INFLORESCENCE: verticillate, interrupted or spicate; bracts leafy. FLOWERS: sessile or subsessile; calyx zygomorphic or actinomorphic, enlarging somewhat in fruit, the lobes or teeth with spinose apices; corolla zygomorphic, 2 lipped, the tube longer or shorter than calyx, the upper lip concave or hooded and mostly entire, the lower lip (2 )3 lobed; stamens 4, included under upper lip or exserted, the anther sacs strongly divaricate with none abortive; ovary sessile, deeply lobed; stigma evenly 2 lobed.

Vascular plants of NE US and adjacent Canada Cal nearly regular, 5-10-nerved, the lobes triangular to nearly lanceolate, acute or aristate; cor strongly 2-lipped, the tube about equaling the cal, the upper lip subgaleately rounded, entire or emarginate, the lower lip spreading or deflexed, 3- lobed; stamens 4, ascending under the upper lip, the lower pair slightly the longer; nutlets ovoid or oblong, usually hairy; herbs, usually hairy, with anthocyanic to white or yellow fls in small, dense axillary cymes subtended by reduced lvs, forming a terminal, loose or dense, usually interrupted spike. Perhaps 200, mainly N. Temp. Spp. 2-8 are intergradient, and further study might lead to a more conservative treatment. Gleason, Henry A. & Cronquist, Arthur J. 1991.
