Leaves opposite, bases connate, c. 35-70 x 2-8 mm, narrowly elliptic, apex ± acute, base narrowed to a petiolar part, margins usually sharply serrate, sometimes subentire, both surfaces puberulous with balloon-tipped hairs up to 0.2 mm long. Flowers many in long narrow lax terminal thyrses, lowermost flowers sometimes solitary, mostly flowers up to 9 in dichasial cymules, occasionally monochasial when one branch fails to develop. Bracts (subtending lowermost flower or cymule) c. 2.5 x 0.75 mm, oblong. Peduncle or pedicel (lowermost) c. 2-6 mm long, flowers otherwise sessile or almost so. Calyx obscurely bilabiate, tube 0.4-0.8 mm long, lobes 1.5-2 x 0.4-0.8 mm, subspathulate, tips somewhat thickened, tiny balloon-tipped hairs on margins only.
