Inflorescences cymules paired or occasionally in 3s, 5 to 10(15) cm, usually short elongated in fruit, proximal-most flowers overlapping or not; bracts absent or occasionally 1 near base; pedicels not elongating in fruit, < 0.5 mm. Flowers spreading; calyces promptly deciduous at maturity, asymmetric, urceolate to ovoid with narrowly acute-obconic base, 1.5 to 2 mm at anthesis, 3 to 4 mm in fruit, lobes basally connate, linear to narrowly lanceolate, basally connate, midribs not appreciably thickened, hairs soft, with longer coarse but not hispid hairs, tips erect to slightly spreading, margins and abaxial surfaces with 1 hair type, usually tufted long soft-hirsute, adaxial surfaces glabrous basally, appressed short-hirsute distal end; corollas rotate, tubes 1 to 1.5 mm, limbs 2 to 6 mm in diameter; fornices white or yellow; gynobases extending to 50% and styles to 75% length of mature nutlet; bracts absent.
