mid cauline deeply, palmately 5–7(–9)-lobed, lobes oblong, margins coarsely dentate;

distal cauline smaller, deeply divided ± to base, lobe margins often entire.

erect, spicate, dense, calyces sometimes overlapping, unbranched or branched, distal stem sometimes leafless, many-flowered, not 1-sided, 2–10 cm, elongating at maturity;

bracts green or purplish, ovate to wide-elliptic, usually 2-fid, sometimes undivided, 2–6(–12) × 2–5 mm.
