Atriplex tularensis
Atriplex klebergorum
Bakersfield smallscale, Tulare orach, Tulare saltbush
Kleberg orach, Kleberg's saltbush
aging red, terete or obscurely angled, brittle.
erect, diffuse;
branches alternate, numerous, horizontal or distally ascending, terete, 1.5–4 dm, densely white farinose when young, glabrate in age;
bark becoming pale brownish white and flaky;
internodes mostly shorter than 1(–2.4) cm.
alternate or proximalmost opposite;
blade lanceolate to ovate, 6–20 × 4–8 mm, base rounded, margin entire, apex acute to acuminate, gray scurfy.
alternate, proximalmost subopposite, sessile;
blade ovate-deltoid, 0.5–1.5(–2.5) × 5–12(–15) mm, rather firm and flat, base rounded, truncate, or slightly clasping, margin entire or toothed, apex acute, very densely canescent-farinose with a greenish yellow tinge.
sessile, axillary, inconspicuous, mostly in leafy lateral branches with extremely short internodes, arising toward tips of secondary branches.
in small axillary dense glomerules, 4-merous.
in most distal axils, 2 mm wide;
sepals 3–5, mostly hyaline, curved elliptic, 1.5–1.7 mm, mucronulate, farinose dorsally.
solitary or in small axillary clusters, below or mixed with staminate.
densely farinose;
bracteoles adnate to ovary.
dark brown, 1–1.2 mm.
dark reddish brown, round-lenticular, 1.5 mm wide, shining;
radicle superior.
bracteoles sessile, rhombic-ovate, acute or acuminate, 2.5–3.5 × 2.2–3 mm, united to middle, thin margin toothed, faces plane, scurfy.
bracteoles variably and irregularly 3–7-cleft, ovate-orbicular, 3.1–4.7 × (3.2–)4–7 mm, typically somewhat constricted below middle, with terminal lobes (1–)1.5–2.8 mm, densely scurfy, faces doubly cristate or smooth.
Atriplex tularensis
Atriplex klebergorum
Of conservation concern.
H. M. Hall and F. E. Clements (1923) discussed the relationship of this plant to Atriplex cordulata, noting that, “A. tularensis is a much more slender plant, the leaves are narrower in proportion to their length,” and tapering to the base, never at all cordate. They noted further, that “The fruiting bracts are sometimes very similar in shape, but those of tularensis typically end in an abrupt acute tooth not present in cordulata and both bract and seed are always smaller.” Because of its small fruiting bracteoles it was placed within the Pusillae by P. C. Standley (1916). The erect stature, coupled with distinctive spreading-ascending and stiff (at least in dried material) leaves, and foliose bracts apparently distinguish A. tularensis from A. coronata.

Of conservation concern.
The species was noted by its author as apparently belonging in sect. Argenteae Standley; I concur with that alignment. The overall shape of the bracteoles with a subterminal constriction is reminiscent of those of Atriplex powellii, but the bracteole shape is otherwise distinctive, and the long marginal teeth and occasional elongate cristate processes on the faces are unmatched elsewhere in the Argenteae.
