Panicles 7–13 x 9–13 cm., many-flowered, with the axis, the divaricate branches and the 3–5 mm. long pedicels purple, densely fulvous-setose; bracts 4–5 mm. long, ovate-lanceolate, acute, shortly setose on the back, early caducous. Receptacle 7–8 x 5–6 mm., cylindric-campanulate, densely setose, the bristles short, subulate, arched-ascending. Sepals 4–6 x 4–5 mm., triangular-ovate or oblong-semicircular, roundish at the top, bright purple, shortly setose on the back, ciliate at margin. Petals 1·7–2·2 x 1·2–1·9 cm., obovate, deep pink.
