摘要

The paper presents a detailed anatomical study of the stem of medicinally important plant – Rumexhastatus. Young stem has ridges and furrows. Epidermis shows sessile mucilage glands in the internodal andnodal region. Subepidermal strands of collenchyma (below the angles), chlorenchyma, tannin filled cells andlarge calcium oxalate crystals (druses) are observed in the cortex. Pericycle is represented by isolated patches ofsclerenchyma present above the vascular bundles. Vascular bundles are arranged in a ring and show gradualincrease in their number. In the mature stem the vascular cylinder is composed of 26 to 28 vascular bundles ofdifferent sizes. A continuous zone of fibres, present at inner margin of the vascular bundles delimits theparenchymatous pith. Stem anatomy of Rumex hastatus is compared with that of other species of the genus anddiscussed.
