bracts usually persistent, ovate, lanceolate, or elliptic.

terminal, often also appearing axillary (from branches proximal to racemes of major branches with vegetative portions highly reduced), 2–10(–15) × 0.8–1.9 cm;

rachis not thorn-tipped;

peduncle to 2 cm, sometimes vestigial, especially on reduced axillary racemes;

bracts mostly deciduous, rarely persistent, lanceolate, narrowly ovate, or linear.
