Inflorescences to 15 per stem, branched to 2 orders, each inflorescence with to 6 pendulous primary branches, these 75-100 cm; rachillae subtended by prominent, ± rectangular bracts 2.5-5 × 2-2.5 cm, glabrous or with few whitish gray, appressed hairs adaxially; male flowers with 6 stamens; female flowers with stigmas to 6 mm.
