Inflorescences racemelike; bracts glandular-toothed, not ciliate. Pedicels 1.3–4.7 mm. Flowers: sepals persistent, outer sepals oblong, 2.3–3.7 mm, margins not scarious, all very coarsely, irregularly glandular-toothed (inner sepals more closely and finely toothed than outer), apex acute; petals pale yellow, obovate, 5–10 mm; stamen length unknown; anthers 0.3–0.7 mm; staminodia absent; styles connate 0.2–1.8 mm at base, 2–4.5 mm; stigmas capitate.
