Abstract
Allium jammuense , a new species from the Trikuta Hills of Jammu and Kashmir, India, is described here as a member of Allium subgenus Cepa section Cepa . The species is discovered based on a combination of morphological characteristics and molecular evidence. Phylogenetic analysis based on nuclear ribosomal Internal Transcribed Spacer (nrITS) sequences supports that A. jammuense is closely related to A. farctum and A. roylei , forming a distinct clade. A detailed morphological description, identification key, comparative table, IUCN status, and photographic plate are provided to support its taxonomic placement.
