The stem bark is characterized by the well developed cork region; phelloderm region consisting number of stone cells and fibres, ceratenchyma is also present in inner phloem region, medullary rays are heterogenous and multiseriate, minute starch grains up to 5 μm in diam. are present in secondary phloem region. Powder of stem bark shown fragments of cork cells, stone cells and sclereids, fragments of fibres, parenchymatous cells, filled with black brown content, acicular crystals and starch grains were also found present.
