This widespread circumpolar species is found in North American and Eurasia. Argus et al. (2012), in Flora North America (2012), indicate that one subspecies has been identified: "A population of Salix reticulata on the Queen Charlotte Islands, with consistently glabrous ovaries, was named subsp. glabellicarpa. Some southeastern Alaska populations have plants with glabrous, partially hairy, and completely short-silky ovaries growing together. The possibility that subsp. glabellicarpa may be a hybrid or a simple mutation needs study."

General: Dwarf shrubs, 3-15 cm tall, spreading by layering; branches trailing, flexible at base; twigs yellow- to red-brown, smooth.
Leaves: Alternate, simple, broadly oblong to broadly elliptic or nearly circular, 1-6.5 cm long, 0.8-5 cm wide, lower surface glaucous, silky to nearly smooth, hairs white, upper surface shiny or highly glossy and deeply net-veined, smooth, entire or obscurely toothed, bases rounded or heart-shaped, tips rounded; leaf stalks with or without glandular dots at top; stipules rudimentary.
Flowers: Unisexual, lacking sepals and petals, borne in catkins which flower as leaves emerge, the catkins stout, on leafy twigs; floral bracts pale; stamens 2; ovaries 1, hairy or smooth; styles 0.2-0.4 mm long.
Fruits: Capsules which split open to release the seeds, each of which is surrounded by a tuft of hairs; stalks 0-0.8 mm long.
Notes: In this species the vegetative twigs almost always terminate in a catkin.
Moist to dry meadows, seepage areas and openings in the alpine and subalpine zones (ssp. reticulata), cliffs and ledges in the alpine zone (ssp. glabellicarpa); common in N BC (ssp. reticulata), rare on the Queen Charlotte Islands (ssp. glabellicarpa); circumpolar, ssp. reticulata - N to NT and E to NF and S to NM, UT and CA; Eurasia, ssp. glabellicarpa - endemic to BC and SE AK.
