Flowering spikes 0.7–1.5 cm long, subspherical to ovoid in flower, elongating in fruit to c. 2(4) cm long and becoming ovoid-oblong to subcylindric; lower floral bracts leaf-like, shorter than the flowering spike, 5.5–10 × 3.5–6 mm, ovate or oblong-ovate, ± acuminate-cuspidate to acute at the apex, truncate or rounded at the base, flat or with ± revolute margins towards the apex, ± inconspicuously nerved, appressed hispidulous-puberulous, only slightly enlarged in fruiting spikes, usually soon caducous in fruit; fruiting spike-axes up to 27 mm long, with ± spaced prominent scars often within the remains of persistent calyces, white hispidulous-pubescent to strigose.
Stems several to many from a woody rootstock, becoming ± woody, somewhat 4-angular, simple or divaricately-branched; branches stout, leafy; branchlets often short with ± crowded leaves; indumentum hispid-pubescent with long whitish tubercle-based hairs usually curving and upwardly directed, twigs sparsely to ± densely hispid-tomentose with long spreading bristles especially on young growth, usually with scattered sessile glands, older branches and stems glabrescent.
A shrub. It grows 1.5 m tall. It can be a bushy herb 20-70 cm high. There are several stems from a woody rootstock. The leafy branches are often short and have leaves crowded together. The leaves are 3-6 cm long by 2-3 cm wide. There are teeth around the edge. The flowering spikes are about 1 cm long. The fruit are about 3 mm long by 3 mm wide. They are dark purple when mature.
Peduncles 1 per leaf axil with 2–3 per node, erect or ascending, 0.2–1.5(2.5) cm long, usually no longer than half the length of the subtending leaf and often shorter than the petioles, elongating in fruit.
Corolla lilac or mauve to pink or purple, with a yellow throat; tube 5–6 mm long; upper lip 2.5–3 mm wide, slightly emarginate; lower lip 4–6 mm wide with the 3 lobes entire, rounded.
Shrub up to 1.5(2) m tall or a ± bushy perennial herb 20–70 cm tall.
Drupes 3–3.5 × 3 mm, lilac to purple or dark purple when mature.
Anthers c. 0.5 mm long, oblong.
