Bistorta tenuifolia var. gidarensis (Polygonaceae), a new variety from India

A new variety of Bistorta tenuifolia, named B. tenuifolia var. gidarensis (Polygonaceae), has been identified from the Great Himalayan National Park Conservation Area and alpine meadows in Uttarakhand, India. This discovery was made during a botanical excursion where researchers noted its viviparous nature and distinct morphological traits, such as acute perianth lobes, minute stamens included within the perianth, and reniform anthers. These features differentiate it from the typical B. tenuifolia and related species like B. vivipara. The study highlights the importance of detailed morphological analysis in identifying new plant varieties, contributing to the botanical diversity documentation of this UNESCO World Heritage Site.
