Description: Tall erect, diffusely branched annual plant reaching 40 cm (16 in.) in height. Stems and branches finely glandular, sticky, and are often covered with adhering sand particles. Leaves basal, kidney-shaped. Inflorescence open and diffuse, peduncles slender, to 2.5 cm (1 in.) long. Individual flowers yellow, 2 mm (0.08 in.) long, smooth to sparsely hairy. Time of flowering: April to May.
Habitat: Occurs in low dunes, washes, beaches, and areas of aeolian accumulation, in loose sandy soils, at 460 - 760 m (1,500 - 2,500 ft)
elevations within Mojave desert scrub community.
Range: Rare eastern Mojave endemic, known from Bunkerville and
Riverside, in the Virgin River drainage from Sand Hollow Wash to confluence of the Colorado River at Middle Point, along Muddy River from Weiser Wash to confluence with the Virgin River. Range of E. viscidulum
somewhat overlaps with Astragalus geyeri var. triquetrus because of
similar habitat features.
Comments: The viscid (sticky) stems distinguish this species from other
related annual buckwheat species.
Special Remarks: This is a State of Nevada Critically Endangered Species.
