The paper highlights the complex nature of Delphinium viscosum Hook. f. & Thoms. in the Himalaya and enumerates two subspecies and two varieties. Critical appraisal of the morphological and distributional data revealed that subsp. viscosum and subsp. gigantobracteum having two varieties var. gigantobracteum and chrysotrichum are distinct. Delphinium viscosum complex is solved out and two subspecies and two varieties with clear cut distinct macro and micro-morphological characters have been identified. The taxonomic status of different taxa of this complex species has been established. Delphinium viscosum, a taxonomic complex species is described and illustrated.
