Opposite, short-stalked to nearly stalked, elliptic to oval, 4-10 cm long, 2.5-5 cm wide, entire, rounded to pointed at tip, glabrous except for a fringe of long hairs along the edges, glaucous beneath; end pair on each flowering twig joined to form a disk around the stem below the inflorescence.
Inflorescence a tight, headlike cluster of flowers on very short stalks in what looks like a whorl, above the disk leaves at branch ends; corollas orange-yellow to red, 2.5-4 cm long, the tubes densely hairy within, bulging on one side at the base, 3-4 times as long as the weakly 2-lipped limbs; upper lips 4-lobed, lower lips narrow, 1-lobed.
