blades light green to yellowish green, linear-lanceolate, occasionally lanceolate, 6–14 × 1–3.5(–4) cm, usually ca. 5–7 times as long as wide, widest near middle, thin, not coriaceous, base cuneate, margins entire, flat or undulate, apex acute or attenuate.
blades linear-lanceolate, occasionally almost linear, 5–13 × (0.5–)1–2.5 cm, usually ca. 7 or more times as long as wide, widest near middle, thin, occasionally subcoriaceous, base cuneate, margins entire, flat or rarely slightly crenulate, apex acute or attenuate.
terminal and axillary, terminal usually occupying distal 1/5–1/3 of stem, rather dense or interrupted in proximal 1/2, usually broadly paniculate (branches simple or with few 2d-order branches).
terminal and axillary, terminal usually occupying distal 1/5–1/3 of stem, rather lax, interrupted in proximal 1/2, or almost to top, usually narrowly paniculate (branches normally simple and short).
articulated in proximal 1/3 or almost near base, filiform (thickened distally), 4–7 mm, not more than 2–2.5 times as long as inner tepals, articulation indistinctly swollen.

inner tepals broadly ovate-triangular, occasionally broadly triangular, 3.5–4.5(–5) × 3.5–4(–5) mm, base truncate or indistinctly cordate, margins entire or indistinctly erose, apex obtuse or subacute;
tubercles 3, equal or subequal (much narrower than inner tepals).
7–20 in whorls;
inner tepals broadly triangular, (1.8–)2–2.5(–3) × 1.5–2.1 mm, base broadly cuneate or truncate, margins entire or indistinctly erose, apex acute;

Rumex mexicanus
Rumex salicifolius
Some authors recognize Rumex mexicanus in the broad sense, including in it many other taxa treated here as separate entities. For consistency, the entities of the R. salicifolius aggregate that are recognized herein are kept separate pending additional taxonomic research.

Rumex salicifolius occurs mostly in southern and central California; it has been reported also from adjacent parts of Arizona (N. M. Sarkar 1958) and Nevada (J. T. Kartesz 1987, vol. 1). The name R. salicifolius has been applied in a broad sense to nearly all species of subsect. Salicifolii, including even mostly Asian R. sibiricus. Rumex salicifolius appears to be most closely related to R. californicus and R. utahensis.
