Abstrakt: Climate change and land use transformation are triggering the shift in species ranges, causing tropicalization of temperate floras and consequently impacting the endemic biodiversity of temperate zones. Therefore, early documentation of such floristic changes is essential for implementing effective management strategies to mitigate the loss of endemic biodiversity. Here we report Amaranthus deflexus L. of tropical origin for the first time from the temperate Kashmir Himalaya, India. Based on the sparse plant populations and restricted distribution, A. deflexus is categorized as a casual alien species for the study region. The taxonomic identification of species was confirmed on the basis of diagnostic floral characters. This study provides a comprehensive micro- and macromorphological description, photographic illustrations, and a comparison of diagnostic characters of A. deflexus with closely related species A. viridis L. and a distribution map to support the scientific validity of the plant distribution record in this Himalayan region.
