The inflorescences are pseudo whorls of three to twelve (rarely up to 14) are mostly apart and consist of two to six flowers . The lower bracts are 4 to 10 mm long and 6 to 8 mm wide and are therefore roughly similar in length to the calyx . They are heart-shaped-lanceolate to almost circular, their edge is slit-toothed. The calyx is 4 to 9 mm long and has a ring of trichomes on the inside. The calyx teeth are green and hairy to tomentose. The crown is 7 to 10 mm long, is usually white or less often pale to dark yellow in color and sometimes has dark brown or purple markings on the inside.
The number of chromosomes is 2n = 26 or 28 + 3B.
