The leaf blades are ovate or triangular-ovate, 2-11cm long, about half as wide as they are long, with small rounded teeth along the margins and covered with long soft hairs on both surfaces. The inflorescence is a cyme with 6 flowers per whorl, forming a 10-20cm long spike; the lower bracts are similar to the leaves, while the upper bracts are ovate with long soft marginal hairs. The calyx is wide and bell-shaped, with a bilabiate corolla that is blue-purple or purple with a yellow base. The corolla tube is about twice as long as the calyx, with a bilabiate limb, the upper lip straight and semicircular, and the lower lip 3-lobed with the middle lobe being the largest. The fertile stamens extend under the upper lip, with flattened filaments, while the sterile stamens are short and small. The style is hidden within the flower, with a slightly enlarged front of the disc. The flowering period is from July to October. This plant is distributed in...
