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.

Rumex mexicanus
Rumex confertus
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 confertus was placed in subsect. Conferti Rechinger f. This species is common and ecologically successful in central and eastern Europe; it may be expected elsewhere in temperate regions of North America.
