Inflorescence terminal, to ca. 10-flowered, 5-10 cm including flowers, pubescent to tomentose; bracts lanceolate to narrowly ellipsoid, 1-3 cm, papery, both surfaces sparsely to densely appressed hairy; flowers sweetly scented. Pedicels 1.2-3 cm, 2-bracteolate near middle; bracteoles opposite, narrowly oblong, 4-8 mm, papery, pubescent, glandular along margin toward base, ± persistent. Sepals broadly ovate, 1.5-2 cm, in older flowers longer and narrower, both sides yellowish tomentose, inside more densely so, base cordate when sepal erect, apex obtuse. Staminate flowers: stamens with filaments unequal in length, longest 1-1.5 cm, glabrous; anthers narrowly ellipsoid, 1-1.2 mm. Pistillate flowers: staminodes like stamens but much reduced; ovary oblong-ovoid, densely yellowish appressed-pubescent; placentas 3 or 4; styles 3 or 4, 0.5-1 mm, ± connate, densely pubescent as ovary, stigmas erect to reflexed, drying black, flattened, triangular, 2-3 mm, irregularly lobed, glabrous or abaxially pubescent.
