Stipules lanceolate, mostly persistent at the upper nodes, sometimes rather early caducous, leaving distinct scars, 5-6 by 3-4 mm. Flowers 1-2, white, sessile on top of a short (3-7 mm), solitary axis, the latter densely covered by numerous bracts over its whole length. Bracts membranous, ovate-acuminate, glabrous, ± 2 mm. Calyx in all c. 6-7 by 3 mm, 5-lobed in the upper half, tubular in the inferior one, ± densely pilose both in-and outside. Stamens 10; filaments glabrous, alternately 2 and 1.5 mm long.
