Inflorescence borne along older branches, subfasciculate or short-racemose, 2-6-flowered, subglabrous, seemingly each subtended by a large, lanceolate, acuminate bract to ca. 10 mm long; rachis to ca. 5 mm long; floral bract ovate, acuminate, 1-1.5 mm long; pedicel subrugose, 6-20 mm long; bracteoles nearly basal, similar to floral bract, margin deciduously glandular-fimbriate.
