Racemes (incl. peduncle) to 30 cm long and 1.5-2 cm wide, ± densely patently puberulous; bracts filiform, 0.75-1 mm, sericeous, very early caducous; pedicel 1.8—3(—5) mm, ± densely puberulous; calyx broadly cup-shaped, (0.5-)0.8-1.3 m n, ± densely puberulous; teeth triangular, acute, (0 3-)0.5 mm. Petals white, cream or pale yellow, oblong, acute, 3-3.5 mm, glabrous or puberulous in the distal portion.
