Flowers born with leaves or precocious, white, fragrant, 1-5, mostly on terminal or less commonly on axillary brachyblasts with 2 pairs of closely set bracts, the outer pair lanceolate-acuminate, 10-14 x 3-4 mm, pubescent outside and without colleters inside, the second pair similar but with colleters within; bracteoles one pair, often of two young leaves, sometimes developing into mature leaves with a pair of ovate or triangular, acuminate stipules, closely set with bracts. Calyx 3-4 mm long, funnel-shaped, hardly projecting above the disc, limb minutely 5-7 lobed, with scattered colleters on the rim. Corolla pubescent, tube cylindric, 17-20 x 3 mm, lobes 5, ovate or elliptic, acute or obtuse, 10-13 x 5-6 mm. Stamens inserted below the throat of the corolla tube.
