Flower buds yellowish, to 5 mm, produced from leaf axils of growing branches in autumn. Racemes lateral in branches of previous year, appearing in spring before or when leaves occur, solitary, robust, 6-15(-25) cm, usually ca. 12 cm, 4-8(-15) mm in diam.; peduncles 1-2 cm; bracts linear-lanceolate or broadly linear, 3-6 mm, conspicuously exceeding calyx (including pedicels) or equaling calyx, 0.3-0.7 mm wide, greenish or membranous, apex acuminate, slightly curved toward outside at anthesis, reflexed after anthesis. Pedicels slightly shorter than or ca. as long as calyx. Flowers larger, 4-merous. Calyx deeply campanulate, base slightly united; sepals ovate, margin membranous, dentate, apex obtuse or acute.
