Explore the detailed structure of the aristolochia stem examined by Dr. Rohini Trivedi from the Department of Botany at MLSU. The stem features an almost circular outline with thick cuticle and multicellular hairs. The cortex is differentiated into outer collenchyma and inner parenchyma, with the inner parenchyma developing chloroplasts to form chlorenchyma. The endodermis, followed by sclerenchymatous cells, forms the innermost layer of the cortex. Vascular bundles show a characteristic arrangement with conjoint collateral endarch, open xylem towards the pith, and phloem towards the outside. Primary structures exhibit wide medullary rays, indicating a primary abnormality. Discover more about the aristolochia plant through detailed images and analysis provided in this study.

Aristolocia Outline almost circular, with thick cuticle and multicellular hairs. Cortex is differentiated into outer collenchyma and inner parenchyma. The inner parenchymatous develops chloroplast as they get sunlight and chlorenchyma. cells thus forms
Endodermis is the innermost layer of cortex with barrel shaped cell which contains starch grains. Endodermis is Followed sclerenchymatous cells which splits in the old stem. The vascular bundles are conjoint collateral endarch and open with xylem towards pith (inside) and phloem towards outside. The bundles are separated from each other by wide parenchymatous rays by pericycle of
The trend is also followed in the secondary tissues separated by wide medullary rays and the xylem appears fractured. As wide medullary rays were present in the primary structure also so it is a primary abnormality. where they are
