Inflorescences cymes (sometimes appearing paniculate), 20–30-flowered, (2–)3-branched; branches not recurved, not forked; bracts similar to leaves, smaller. Pedicels 1–3.6 mm. Flowers 5-merous; sepals erect, connate basally, green, ovate or lanceolate, equal, 6.5–8.5 × 3–4.5 mm, apex obtuse or acute, (glandular-pubescent); petals erect, (convolute), connate basally, sulphur yellow, oblong-lanceolate, not carinate, 12.5–16 mm, apex aristate, (glandular-pubescent); filaments greenish yellow; anthers yellow; nectar scales white or translucent, narrowly reniform.
