Inflorescences shorter than or rarely equal to leaves, usually 120–500-flowered; bracts 12–20 mm long, caducous. Sepals 1.3–2 mm long, rarely slightly glandular-verrucose, pubescent. Petals imbricate, 3–6.5 mm long, creamy white, gland-dotted abaxially, pubescent or hirsute adaxially. Filaments glandular-verrucose apically, dilated basally. Cocci apiculate, glabrous.
