Atriplex linearis
slenderleaf saltbush, thinleaf fourwing saltbush
sessile;
blade narrowly linear-elliptic, 10–50 × 2–3 mm, firm, revolute, often acute apically.
in glomerules borne in slender interrupted mostly paniculate spikes.
paniculate or in few-flowered axillary glomerules.
bracteoles sessile or subsessile, lanceolate to ovate, 4–6 mm, about as wide, each bract with a pair of thin wings 3 mm broad or less, irregularly dentate or laciniate, free tips of bracts much exceeding the wings.
= 18.
Atriplex linearis
Specimens of Atriplex canescens var. macilenta resemble A. linearis. The taxa have been placed together by some previous workers. Nevertheless, the stems of A. linearis are consistently more slender, the leaves proportionally narrower, and the bracts, though smaller, more closely simulate those of A. canescens. Its diploid nature signals a different evolutionary pathway than that for most of A. canescens, considered broadly. Narrow leaves occur within A. canescens, in the broad sense, sometimes with geographic correlation, sometimes not.
