Objective: In order to develop its resources from Amaranthus spinosus

an efficacious and widely used folk medicine

standards for its histomorphological characters were set in this study. Method: Its species were identified by observing plant morphology

herb appearance characters and microscopic identification through different routine slice-making methods. Result: According to results of plant morphological observation

there were 2 pieces of thorns in the leaf axil and some of bracts became very sharply spiny.The whole herb could be used in medicine

mainly including the root

stem and leaves.According to findings in the study on microscopic identification

abnormal vascular bundles structure were observed in transverse section of the root and stem;cluster crystals of calcium oxalate and sandy crystals were scattered in parenchymatous cells;vessels

glandular and non-glandular hairs were observed in the powder identification. Conclusion: Herbs of A. spinosus can be identified by these above histomorphological characters

which lay foundation for further development and application of A. spinosus.
