Intermountain Flora
Shrubs to 1.5 (2) m tall, unarmed, strongly aromatic; stems erect to ascending, the young twigs crisped-puberulent, with sessile, yellow glands, the bark at first yellow-green, becoming gray, eventually becoming reddish-brown following exfoliation of the outer layer; leaves all on elongated stems with distinct internodes, petiolate, the petiole (1) 2.7-8 (9.5) cm long, glabrous to hairy, the pubescence often increasing toward the base, with scattered, sessile, round, yellow glands, the blade (2) 2.7-9 (13.3) cm long, (2.8) 3.8-13.5 (17.3) cm wide, reneiform to orbicular, deeply cordate basally, primarily 3-lobed less than half the length into broadly deltate and coarsely bicrenate-dentate segments, the lateral lobes again lobed but less deeply so, the upper surface mostly glabrous, seldom sparsely pubescent (in our range), ciliate, the lower surface with scattered pilosulose pubescence (especially along the veins and especially when young) and sessile, round, yellow glands; racemes 20-50-flowered, erect to spreading, (4) 6.5-15 (17) cm long; flowers subtended by linear to linear-lanceolate bracts 0.5-2 (3) mm long, the pedicels 0.6-8 (11) mm long, jointed below the flower; hypanthium 0.6-1.5 mm long from the top of the ovary to the base of the sepals, flared and somewhat saucer-shaped, sparsely to densely pubescent, usually with sessile, yellow glands externally, glabrous within, white, lined with a disk; sepals 3.4-5.1 mm long, (1.6) 2-2.7 (3.1) mm wide, widely spreading, broadly lanceolate, pubescent externally and within (especially near the apex), white; petals 0.9-1.7 mm long, 1.2-1.6 (2) mmm wide, becoming cuneate-flabelliform upward, white; stamens inserted slightly below the petals, 1.5-2.1 mm long, the filaments 1-1.1 mm long, glabrous, the anthers 0.4-1 mm long, oval; styles connate slightly more than half their length; berry 5.5-12 mm in diameter, sublgobose, glabrous except for the sessile, yellow glands, black and sometimes glaucous, bitter and barely palatable; seeds 1.2-2 mm long, dark reddish; 2n = 16.
