Calyx-lobes 1.5–3 mm long, entire or toothed; corolla weakly 2-lipped, 5.5–11 mm long, blue to light violet, lobes spreading, subequal or upper 2 slightly narrower and/or more deeply cleft, narrowly elliptic to oblanceolate, 2.5–6.5 mm long, 0.8–2.5 mm wide, tube 3–5 mm long, split almost to base, with fine retrorse hairs internally; filaments 2.5–4 mm long, anther tube 1–2.2 mm long in male and bisexual flowers, c. 1–1.5 mm long in females, 2 lower anthers each with an apical seta 0.2–0.5 mm long and penicillate hairs, the apex of the upper 3 anthers with a very inconspicuous crest-like tuft of hairs.
