Abstract
The anatomical characterisation of medicinally and economically important species of Hedycium coronarium (zingiberaceae) was done in this study. Anatomy of the Stem, Leaf, Flower and Rhizome were observed. Histochemical nature of the cells studied and presented in this paper. The species shows diagnostic anatomical characters such as Endodermoid layer, starch grains, oil cells are present. H. coronarium is an herbaceous, rhizomatous perennial plant, it accumulates essential oil which is used as a condiment, in perfumery, and as a medicine. The plant are also rich in phytochemicals and rich in antioxidants. Essential oil droplets and abundance of starch grains was observed under light microscope in thin sections of rhizome and stem. Some crystalline structures are visualized and are examine to further studies for identification and usage in pharmaceutical purposes. Anatomical characters of the rhizome in zingiberaceae could not only help in the identification of the plant species but also in authenticating plant materials used in medicine. The aim of the present study is to elucidate the morphological and anatomical characters of H. coronarium. And also to identify the various cell types that includes starch grains, oil cells, resins, crystals etc. for further studies.
