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).
