Hooker bugseed, Hooker's bugseed
blades linear-oblanceolate (linear-spatulate) or linear, often broadest in distal 1/3, plane, 1–3.5 × 0.1–0.3 cm, abruptly contracted into mucronulate apex.
blades narrowly lanceolate or linear-lanceolate, plane, 2–5 × (0.1–)0.2–0.5(–0.6) cm.
ovate-lanceolate, lanceolate, or linear-lanceolate (proximal bracts usually linear, leaflike, 4–7 times fruit length), (0.5–)1–1.5(–3) × (0.1–)0.2–0.5 cm.
ovate or ovate-lanceolate, 0.5–1.5(–2) × 0.3–1 cm.
compact and dense, short-clavate or almost ovoid (if linear, then all bracts leaflike).
usually dense, ovoid, ovate-clavate, or ovate-cylindric, rarely interrupted near base.

wing translucent only at margins, thick, (0.1–)0.2–0.3 mm wide, margins entire, apex broadly triangular or almost rounded.
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;

Corispermum ochotense
Corispermum hookeri
Varieties 2 (2 in the flora).
Corispermum ochotense is conspicuous in that it is usually red at maturity. No specimens of Corispermum have been seen from Yukon Territory, but the species might be expected there. One collection of immature plants from northern Saskatchewan (see S. L. Mosyakin 1995) probably also belongs to C. ochotense. Specimens of C. ochotense have been misidentified in North America and northeast Asia as C. hyssopifolium Linnaeus and C. sibiricum Iljin.

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.
