Until 2016, two subspecies of this taxon were recognized in BC: ssp. ferruginea and ssp. glabella. Illustrations still reflect the former taxonomy.

Species Information

Erect to spreading, straggly shrub; stems 0.5-2 m tall, somewhat skunky odour when crushed, finely hairy, hairs somewhat glandular and rusty-coloured; older branches with loosely shredding bark, often glabrous.
Deciduous, alternate, clustered at stem tips, thin, elliptic to broadly egg-shaped, 1-6 cm long, 0.3-2 cm wide, glandular-hairy on both surfaces, pale beneath, margins fine-toothed and fringed; stalks
In (1) 2- to 10-flowered clusters, terminal on shoots of previous year; flower stalks 0.7-3.5 cm long, short-hairy to conspicuously glandular-hairy, curved downward in flower, erect in fruit; corollas salmon to greenish-orange, urn-shaped, 4-lobed, 6-9 mm long; calyces saucer-shaped, indistinctly 4-lobed, 1 mm long or less, glandular-hairy along margins; stamens glabrous to sparsely hairy near the base.
Capsules, egg-shaped to lance egg-shaped, 5-7 mm long.
Two infraspecific entities are generally recognized.

1. Leaves pointed, with glandular hairs; calyces glandular-hairy on margins; ovaries glandular-hairy..................ssp. ferruginea

1. Leaves more than pointed, minutely-hairy on both sides, less conspicuously long-hairy above and less glandular below; calyces usually finely hairy as well as glandular hairy on margins; ovaries finely- and glandular-hairy..................ssp. glabella (A. Gray) Calder & Taylor.
