    Flowers
    Flowers in long lax terminal and axillary leafy racemes; pedicels up to 5–13 mm. long, glabrous, papillose or pubescent; upper bracts linear to narrowly elliptic, longer than or rarely equalling pedicels; bracteoles 0.3–0.8 (–2) mm. long, at the base of the pedicel.
    Hypanthium
    Hypanthium narrowly obconical to subspherical, ± 8-nerved, glabrous or rarely pubescent.
    Calyx
    Calyx-lobes narrowly triangular to subulate, ± erect, spreading, or recurved in fruit, 1.2–3.6 (–5) mm. long, entire or rarely with a single tooth at the margin, glabrous or rarely ciliate.
    Corolla
    Corolla 4–11 mm. long, blue with darker markings, split to 0.1–1 mm. from the base on the back, glabrous outside, papillose or shortly pubescent inside at the bottom of the tube.
    Filaments
    Filaments, at least the 2 lower, pubescent below, attached to the corolla-tube at the base.
    Anthers
    Anther-tube 0.8–2 mm. long, shortly pubescent on the back at least near the apex or rarely glabrous; 2 lower anthers each with a tuft of hairs and a hyaline appendage at the apex.
    Ovary
    Ovary subinferior.
    Fruits
    Capsule narrowly obconical to subspherical, ± 8-nerved, glabrous or rarely pubescent, with 2 valves 0.6–1.2 mm. long, inferior part of capsule 2.4–6 mm. long.
