Description

"Annual or perennial herbs with erect, or ascending to prostrate, quadrangular stems. Leaves simple, opposite. Flowers in terminal, bracteate spikes, the spike usually cymose, paniculate, or solitary. Calyx 5-lobed, lobed united to near apex, the lower usually longer than the upper; corolla salverform, zygomorphic to nearly actinomorphic; stamens included, attached to upper part of corolla tube at 2 levels; stigmas 2, style 1, locules 3. Fruit a schizocarp of 3 mericarps. Mericarps oblong, brown, usually lustrous, and rounded on back, white, grayish or tan, warty or muricate, and flattened on inner surface. Mericarps that separate readily are usually more warty or muricate than those that adhere tightly." - Radford et al 1964

"Erect to ascending perennial, nonstoloniferous, 4-9 dm tall, branched above. Leaves elliptic, oblong or oblanceolate, 4-9 cm long, 1.2-3 cm wide, obtuse to acute, serrate, usually doubly, base attenuate, the uppermost pair of leaves just below the first branches usually pair of basal lobes. Spikes 1-5, terminating the stem, stiffly erect or arching, 1.5-4 dm long, 8-12 mm in diam., flowers imbricate to distant, fruit distant; bracts 1/2 -1X length of calyx. Calyx 3-4.5 mm long, lobes curved inward, not connivent in fruit; corolla pink or pinkish lavender, more than 2X as long as the calyx, lobes 4-6 mm long; bracts, calyx and corolla tube pubescent. Rachis stipitate-glandular. Mericarps all well developed, tightly adhering, appearing as one, 2.8-3 mm long." - Radford et al 1964
