The leaves are ovate, rhombus-ovate or ovate-oblong, (1.2)2-5.5cm long, (0.8)1.3-3.5cm wide, with an acute apex, a broad cuneate to truncate cuneate base, coarsely dentate or sparsely crenate on the margin, with small cusps at the ends of the teeth, papery, olive green above, gray-green below, pubescent on both sides and with scattered sunken glandular dots, sparser pubescence on the upper side, 4-5 pairs of lateral veins, obliquely ascending, slightly prominent on both sides; petiole (3)5-15mm long, flat on the abdomen and convex on the back, pubescent. The cyme has 6 flowers, forming a raceme with a peduncle 8-12 cm long at the top of the main stem and side branches; the bracts are round-ovate, about 3.5 mm long, about 3 mm wide, with a sharp tip, entire margin, parallel longitudinal veins, glabrous above, densely pubescent below, with small cilia on the edge; the pedicels are up to 5 mm long and densely pubescent along the axis of the order.

The calyx is ovate, 5-6mm long and about 2.5mm wide, covered with fine soft hairs and protruding rusty glandular dots on the outside, glabrous on the inside, two-lipped, the upper lip is rounded, about 2.5mm long and wide, and the edge extends down to the calyx tube. The lower lip has 4 teeth, which are triangular and have awns at the tip. The first 2 teeth are twice as long as the lateral 2 teeth, and both have short eyelashes on the edges. When fruiting, the calyx enlarges, up to 1.1cm long and 5mm wide, with 10 obvious veins, among which the reticulated veins are clearly visible. The upper lip is obviously turned outward, and the lower lip extends forward. The corolla is light purple or white, pubescent on the outside, with sparse rusty glandular dots on the upper lip, and sparse pubescent on the inside at the lower part of the corolla tube. The corolla tube is narrowly tubular, 9-19mm long, nearly equal in size, and about 1mm in diameter. The corolla is large, two-lipped, with the upper lip large, outward-reflected, about 6mm in diameter, 3-lobed, the middle lobe larger, slightly emarginate at the apex, and the lower lip straight, oblong, about 5mm long, about 2.5mm wide, and slightly concave. There are 4 stamens, which extend 2-4cm beyond the corolla. The front pair are slightly longer. The filaments are long and filamentous, without teeth. The anthers are small and the anther cells are forked. The style is long and protruding, with a club-shaped tip and 2 shallow lobes. The front of the disk is finger-like inflated. The nutlets are oval, about 2 mm long and 1.6 mm wide, dark brown and wrinkled. Flowering and fruiting period is from May to November.
