General: Skeletonweed (Eriogonum deflexum), also called Flattop Buckwheat, is a perennial forb with a small basal rosette of thick, dark green leaves, usually a single erect main stem to about 18-inches tall, and many terminal branches. The terminal branchlets are thin and wispy. Flowers hang from the terminal branchlets. This species is similar to Desert Trumpet, except that the stems are not inflated.

Skeletonweed is a common component of vegetation communities in dry, well-drained sandy and gravelly areas on desert flats, bajadas, and moderate slopes in the lower mountains in the Lower Sonoran (Creosote-Bursage Flats) and Upper Sonoran (Mojave Desert Scrub and Pinyon-Juniper Woodland) life zones.

Flowers: Inflorescence: many slender branches. Flowers tiny, oblong, 1-3 mm, reddish; hang from terminal stems.

Seeds: Achene; small (2 mm).
