Flora of North America species comparison

(5–20), gray-green, glabrescent.

gray-green to brown, glabrate (diffusely branched from bases, brittle).

persistent, gray-green, mostly basal;

proximal blades reduced, mostly less than 1 cm, lobed or entire;

distal blades 1–2 × 0.5–0.8 cm, 1–2-ternately lobed, lobes 1–2 mm wide, apices acute, faces densely tomentose.

(vegetative stems) persistent, gray-green;

blades broadly to narrowly cuneate, 3–10 × 2–5 mm, lobed (lobes 3, oblong-linear, to 1/3 blade lengths, mostly 1–3 mm wide, flat, obtuse, laterals sometimes 2–3-fid; leaves on flowering stems deciduous, blades narrowly cuneate, deeply 3-lobed), faces densely hairy (not sticky resinous).

globose, 3–4 × 3–4 mm.

campanulate or globose-ovoid, (1.5–)2–4(–5) × 1.5–4.5 mm.

pistillate 4–7; functionally staminate 5–9;

corollas yellow, usually red-tinged, 2–3 mm, glabrous.

4–6(–10);

corollas 1.5–2 mm, glabrous.

(margins scarious, obscured) white-tomentose.

(margins green) ovate (outer) to oblong, pubescent or tomentose.

(mostly 6–15, 1 or 3–4 on lateral branches; mostly erect, sessile or pedunculate) in racemiform-paniculiform arrays, 5–8 × 0.5–0.8 cm.

usually borne singly, rarely (1–4, erect, mostly sessile, in pedunculate clusters) in spiciform or paniculiform arrays 2–9 × 0.5–2 cm (branches slender).

(brown) ellipsoid (angled), 0.8–1 mm, (sometimes with white ribs) glabrous.

(light brown) 0.7–0.8 mm, resinous.
