    Inflorescences
    Scorpioid cymes both lateral and terminal, simple in the limited material seen, 1–9 cm. long, the flowers sessile, very dense and touching or at least closely placed, the axes with similar indumentum to the stems.

    Corolla white; tube just under 3(–4 fide Chiovenda) mm. long, the upper 2/3 pubescent outside, the base glabrous; lobes oblong or ± round, 1.2–2 mm. long, 0.8–1.5 mm. wide, rounded.
