Indian botanists and researchers have discovered two new species of plants from the bio-geographic hotspots of the Andaman and Nicobar islands and Arunachal Pradesh.

Discoveries and Researchers

  • Dendrophthoe longensis:
    • Discovered by: Team led by scientist Lal Ji Singh.
    • Location: Long Islands of middle Andamans.
    • Details: Aerial stem-parasitic flowering plant species found on Mango (Mangifera indica).
    • Habitat: Edge of evergreen forests, low land areas of tropical forests.
    • Family: Mistletoe (a group of hemi-parasitic flowering plants).
  • Petrocosmea arunachalense:
    • Discovered by: Team led by scientist Krishna Chowlu.
    • Location: Mandla region of the West Kameng district in Arunachal Pradesh.
    • Details: A very small herb found inside a cave, indicating low sunlight requirements.
    • Family: Gesneriaceae.
    • Appearance: Completely white with a purple blotch and a hairy texture.

Details of Dendrophthoe longensis

  • Distribution:
    • Sparsely scattered and confined to a few localities of Long Island.
    • Specifically recorded in Sigmendera, Lalaji Bay, and near the forest guest house of Long Island.
  • Conservation Status:
    • Assessed as “Endangered” based on the IUCN categories and criteria (IUCN, 2020).
    • Indian Dendrophthoe are represented by nine species, four of which are from the Andaman and Nicobar Islands, with two species being endemic to the region.
  • Threats:
    • Destruction of natural habitat and other anthropogenic activities, especially timber harvesting of host tree species.
    • Developmental works causing population declines worldwide.
  • Publication:
    • Details of the discovery published in an International Journal of Botanical Taxonomy and Geobotany.

Details of Petrocosmea arunachalense

  • Location:
    • Discovered in a remote bio-geographic hotspot in Arunachal Pradesh.
  • Significance:
    • Significant addition to the plant family Gesneriaceae.
    • Only the second known species from the genus Petrocosmea in India.
  • Publication:
    • Research documented in a research article published in the latest issue of the Nordic Journal of Botany.
  • Contributors:
    • Researchers Akshath Shenoy and Ajit Ray from the Arunachal Pradesh Regional Centre, Itanagar of the Botanical Survey of India.
  • Biodiversity:
    • Highlights the rich biodiversity of Arunachal Pradesh, known for its diverse and often unexplored flora.
