Inflorescence flat-topped, densely corymbose, the primary branches opposite, usually spreading at less than 450, branches densely puberulous to subtomentose, the ultimate branches 0-2 mm long. Heads ca. 6-7 mm high; involucral bracts narrowly oblong-lanceolate, 4.5-5.5 mm long and 0.7 mm wide, slightly striate, minutely glandular-punctate, scarcely scarious on margins; corolla white, ca. 4.5 mm long, glandular punctate with few short hairs on tubes and lobes, the lobes equal, ca. 1.2 mm long.
