Cymes lax, arranged in terminal few-branched panicles.
Flowers with pedicels 1.5–3.0(5.0) mm. long, accrescent up to 10 mm., not or only a little recurved in fruit.
Calyx 1.3–2.0 mm. long, divided to near base, lobes lanceolate to oblong-ovate, roughish to shortly hispid outside, ciliate, acute to rounded at apex.
Corolla 2.5–3.5 mm. long, usually deep blue, glabrous; tube 1.2–1.8 mm. long, campanulate; lobes 1.0–2.0 x 1.0–2.0 mm., very often subcircular, sometimes transversely broadly elliptic; fornices much broader than long.
