- In this research, morphology and anatomy of Bidens pilosa var. minor (Blume) Sher. of tribe Heliantheae belonging to the family Asteraceae were studied, photomicrographed and described. The plant is annual erect herb. Leaves are trifoliolate compound and the florets of rays and disc in a head are bisexual and monoecious heads are also found. In anatomical characters, although endodermis are inconspicuous only in roots, it is conspicuous in stem and root. The stomata types are anomocytic and vascular bundles are bicollateral, open and covered by one-layer of bundle sheath.
