Pedicels erect, 5-45 mm, softly pubescent. Flowers 10-16 mm diam.; sepals 5, obscurely veined, narrowly triangular, (5-)7-10(-12) mm, margins narrow, membranous, apex acuminate, glabrous or with shortly ciliate margins; petals 5, equaling to slightly shorter than sepals; stamens 10; styles 3, ascending, ca. 2.5 mm.
