Material and Methods
Based on field information recorded between 2018 and 2022 from the natural populations along the Tawi river bank. The purpose of the current research was to establish a taxonomy treatment ofPsammogeton based on its morphological and anatomical characteristics. Herbarium sheets were made following the recommended procedures (Jain and Rao (1977), Bridson and Forman (1999). The vouchers for the new species are kept in Indian Institute of Medicine (IIIM) at the Jammu, Janaki Ammal Herbarium with abbreviated RRLH indexed in Thiers 2018. We got in touch with a number of herbaria that house closely similar species including POWO 2023. Both living samples and the herbarium sheets were examined for the study of plant morphology. For the stereoscopic observations, a razor was utilised to make mericarp sections. The descriptive terminology for important structural characters follows Hickey (1973), Harris and Harris (2001), Kljuykov et al. (2004).
