General: Seep Willow, also called Mule-Fat (Baccharis salicifolia), is a fairly large shrub with long, linear leaves that look like willow leaves, but it has flowers rather than the catkins of true willows.

As with true willows, Seep Willow is a fairly common component of vegetation communities in canyons, along streams, and other moist places in the Lower Sonoran (Creosote-Bursage Flats) and Upper Sonoran (Mojave Desert Scrub) life zones.

Family: Sunflower (Asteraceae)
