Staminate flowers lack bracts and petals. They are comprised of four sepals and four stamens borne opposite the sepals. Pistillate flowers lack both sepals and petals. Pistils are enclosed by a pair of bracts that are united more than half their length. The bracts are covered and often obscured by long, silky hairs (fig. 31). These long hairs distinguish winterfat from species of Atriptex. Site and climate permitting, winterfat blooms between May and August. The fruit ripens from September to November and is dispersed by wind in late fall and winter. Seed production is extremely variable. A scant crop is produced in most years. How- ever, a heavy seed crop can be produced in years of good summer storms coupled with the absence of summer grazing. Such productive crops on dry desert ranges may occur but once in a decade. Cleaned seeds of this shrub average 112,275 per pound (248/g) {Plummer and others 1968)..
