Fruits usually deep olive green, brown, or rarely to almost black, usually without spots and/or warts, or occasionally spotted, strongly convex abaxially, prominently concave to almost plane adaxially, usually broadest beyond middle, (3.2–) 3.5–4.5 (–5) × 2.2–3.3 (–3.5) mm; wing (when present) semitranslucent, to 0.2 mm wide, margins entire, apex rounded or indistinctly triangular.

Discussion

Varieties 2 (2 in the flora).

The inflorescence bracts of Corispermum hookeri are conspicuously imbricate (usually strongly overlapping). Corispermum hookeri seems to be closely related to the narrow-winged taxa, C. villosum and C. ochotense, and to C. pallasii sensu stricto. The names C. orientale and C. hyssopifolium have been commonly misapplied to this species.
