Plants synoecious, with basal rosette of leaves usually not persistent at maturity. Stems ascending, spreading, or almost prostrate, occasionally erect. Leaf-blades spatulate, lanceolate, or ovatelanceolate, rarely rounded, base cuneate. Pedicels articulated in distal part, usually heteromorphic: some curved, swollen, and clavate, others straight, not swollen, and cylindric. Flowers normally bisexual; outer tepals not spreading; inner tepals enlarged, often heteromorphic, (1.5–) 2–4 (–5) mm, equaling or slightly wider and longer than achenes, margins usually dentate; tubercles very small, or absent.

Distribution

Introduced; s Europe, sw Asia, n Africa, occasionally in other regions

Discussion

Species 1.

Sometimes subg. Platypodium is recognized as a separate genus, Bucephalophora, together with other segregates from Rumex in the broad sense (see Á. Löve and B. M. Kapoor 1967).
