Racemes up to 15 cm long, axillary or terminal, simple, unarmed, puberulous; bracts conspicuously aristate apically, up to 9 mm long including a terminal arista ±2 mm long, up to 8 mm wide, broadly elliptic to suborbicular, concave, ± scarious, pinkish-brown, appressed-pubescent, deciduous before the buds they subtend open. Flowers pink or red, on appressed-pubescent pedicels 3-5 mm long. Sepals dark red, 5-7 mm long, the lower sepal larger and cucullate, forming a hood over the other sepals and with a very conspicuous apical upwardly-curved rostrate beak 2.5-4 mm long, reflexing with age; all sepals appressed-pubescent.
