Flowers: Inflorescence of 1-several, very dense verticillasters, the flowers curved downward; calyx 1.5-6 mm. long, the 5 segments truncate to acute, the margins scarious; corolla deep blue-purple, 6-11 mm. long, the tube narrow, 2-3 mm. wide at the mouth, not strongly bilabiate, the raised part of the lower lip bearded; staminode usually bearded, sometimes glabrous; pollen sacs glabrous, sub-rotund, wholly dehiscent and opening wide enough to form a plane.
