Taxonomy and threat assessment of Lagotis kunawurensis Rupr. (Plantaginaceae), an endemic medicinal plant species of the Himalaya, India

Main Article Content
Abstract
Lagotis kunawurensis Rupr. (Plantaginaceae), a rare plant species endemic to the Himalaya, is reported here after a gap of 50 years from Ladakh. This species has often been taxonomically misidentified and confused with Picrorhiza kurroa, an important medicinal plant of the Himalaya. The present study clarifies the taxonomy of L. kunawurensis by providing description and photo illustrations of diagnostic characters which will aid its proper field identification. Furthermore, the threat assessment of L. kunawurensis using the IUCN Red List of Threatened Species has been conducted based on the available occurrence records, and the species currently falls under the ‘Near Threatened’ category. This species is used for medicinal purposes by locals in the study area. As the species is simultaneously experiencing various kinds of threats and the known distribution range is relatively smaller, it is right time to develop conservation strategies for the sustainable utilization of this endemic medicinal plant species of the Himalaya.
