Atriplex wolfii var. wolfii

Common names: Wolf’s orach
Treatment appears in FNA Volume 4. Treatment on page 355.

Stems erect, intricately branched, mostly 1–3.5 (–4.5) dm. Leaves: proximalmost blade linear to linear-lanceolate or linear-elliptic, mainly 5–25 × 1–4 mm, tapering to slender base, densely grayish scurfy. Staminate flowers mainly confined to distal axils. Fruiting bracteoles oblong-cuneate to obovate in profile, (1.8–) 2–2.3 × 1.1–1.5 mm, terminal tooth reduced to mere cusp between larger lateral ones.


Phenology: Flowering summer–fall.
Habitat: Saline areas growing with shadscale, seepweed, Russian thistle, fine-textured substrates
Elevation: 2300 m

Discussion

While H. M. Hall and F. E. Clements (1923) understandably mixed the two varieties in the specimen citations, they were right in recognition of a rather remarkable difference in bract structure.
