Leaves opposite or sometirnes alternate in the upper part, shortly petiolate or spatulate, obovate to orbicular, 7 - 20 mm, entire, sparingly crenate or bluntly dentate, sometimes papillose.

 

Inflorescences dense cymes with (1-) 5 - 15 (-25) flowers on (1-) 2 - 3 (-4) usually simple cincinni, bracts large, spatulate to oblong, ± 5 mm.

 

Flowers (4- to) 5-merous, (sub-) sessile, sepals basally connate to 1 mm, erect, broadly linear to lanceolate, papillose at the tip, 4 - 6 mm, petals basally free, oblong, broadly mucronate, 4 - 5 mm, white, pink or purplish-red, anthers red.
