The leaves are pubescent on both surfaces. The leaves are deltoid-ovate to cordate-ovate in shape, the blades ranging from 6-15 cm long and 2.5-8 cm wide. The petioles are 1.5-4.5 cm in length. The margins are coarsely crenate.

The flowers are arranged in a series of verticels or whorls, the flowers being axillary to the leaves or bracts (on the upper part of the stem). The calyx ranges from 8-11 mm in length with glandular hairs and spine-tipped teeth. The corolla is a deep red-purple with a long tube ending in two lips, the lower lip being the largest. The tube measures 15-25 mm long and the lower lip is from 8-14 mm long. The anthers spread out flat.
