Inflorescence terminal or axillary, racemose, 4-6 cm; upper bracts linear to lanceolate, 1.5-2 mm, papery, pubescent, hairs semiappressed. Pedicels 2-3 mm, articulate at middle, pubescent, hairs semiappressed. Flowers numerous, inserted along rachis singly or in pairs, (8-)10-merous, 6-8 mm in diam. Calyx tube 2-3 mm, longitudinally ribbed, pubescent, hairs whitish, appressed, short, ca. 0.2 mm; sepals 2-3 × ca. 0.5 mm, linear or linear-lanceolate, both sides sparsely pubescent, hairs appressed, margin ciliate, hairs spreading or semispreading, mostly longer than those on calyx tube; sepal apex mucronate. Petals subequal to sepals in size, or longer (to ca. 4 mm) and broader as fruit develops, outside sparsely appressed hairy, inside with hairs denser, longer, more closely appressed, margin ciliate, hairs spreading, white, straight, to ca. 0.5 mm. Disk glands ca. 0.5 mm in diam. Stamens 3-5 mm, overtopping perianth, sparsely pubescent except in upper 1/3, hairs spreading. Free part of ovary sparsely pubescent throughout, hairs spreading, white, long; styles 4, ca. 4 mm, joined in basal 1/4 to form a short column, hairy except in distal 1/3, hairs spreading, white, long; placentas 3, each with 3 or 4 ovules.
