Rumex punjabensis Vaid & Naithani, Indian Forester. 105: 802. 1979; Fl. Pak. @ eFloras.org Pakistan V. 205.

Perennial herb. New plants with basal leaves arise from older rootstocks in spring season. Stem erect, 50-100(-180) cm tall, sparsely branched with arcuate divaricate branches from about the middle, forming an open broad panicle, grooved, glabrous. Ochrea tubular, membranous, fugacious. Leaves basal and cauline; basal leaves: petioles 12-15(-25) cm long; leaf blade ovate-oblong, 17-25(-54) cm x 7.5-10(-20) cm, broadest below or at the middle, attenuate towards acute apex, base cordate, margin flat and/ or undulate, both surfaces glabrous or papillose along veins abaxially; lower and middle cauline leaves gradually smaller and narrower, with shorter petioles and less deeply cordate base; uppermost cauline leaves gradually still smaller up to 3 cm x 0.7 cm with rounded or attenuate base, gradually tapering towards apex. Inflorescence racemose, several racemes aggregated and panicle-like in upper half of plant, panicle lax. Flowers actinomorphic, bisexual, hypogynous, spreading or pendulous, green, in dense whorls, whorls all distant except uppermost. Pedicels 5.5-6.5(-7.5) mm long, articulate, joint below middle. Tepals 6, connate proximally, in 2 whorls of 3 each; outer perianth segments 1.6-1.8 mm long, appressed to the base of inner perianth (valves); inner perianth segments larger and broader, subsequently forming “valves”. Stamens 6, in 2 whorls of 3 each; filaments short, glabrous; anthers ca. 1 mm long, bithecous, oblong. Carpels 3, syncarpous; ovary trigonous, unilocular with solitary basal ovule; styles 3. Achenes (nuts) ca. 2 mm long, dark brown. Fruiting perianth segments (valves) 5-5.5 mm x 6-7 mm, broadly cordate-scutiform (shield-shaped), often broader than long; with broadly attenuate apex; irregularly tubercle bearing, tubercle of the anterior valve longer than the posterior, sometimes tubercle absent; margin of basal half with 7-8 (sometimes more) small straight teeth, 0.25-0.5 mm long, margin of upper half entire; surface conspicuously net-veined.
