Panicles 1-3 together, up to 30 cm, erect, pendent in fruit, glabrous, or finely pale puberulous, or ferrugineous velvety; branches patent to recurved in fruit, up to 14 mm, sometimes once forked near the top, subtended by a bract, a petioloid, or a small leaf. Lower and upper joints of pedicel subequal, ½-1 mm. Calyx 1¼-2 mm high, outside glabrous or very shortly pale puberulous or ferrugineous puberulous. Sepals 1¼-2 by 1-2 mm, broadly ovate to spathulate, obtuse to emarginate. Petals 4-7 by 1¼-2 mm, obovate-lanceolate, rounded to emarginate, whitish to dark red. Filaments in SF 1-2¼ and 2-3½ mm, in LF ½-1 and 1-1½ mm. Pistil glabrous to appressed-strigose, in SF 1-1½ mm, in LF 3-4 mm long; styles in SF 0.5 mm, in LF 2-3 mm long; ovary ¾-1 by 0.5-⅔ mm, ellipsoid. Fruit 6-13 by 4-9 mm, ovoid to ellipsoid, recurved, rounded to acuminate, glabrescent; rimae inconspicuous, closed not lighter nor glandular inside.
