In News: New species of Miliusa spotted in Agasthyamala

  • Researchers have identified a new species of evergreen tree belonging to the genus Miliusa from the Agasthyamala biosphere reserve in the southern arm of the Western Ghats in the Thiruvananthapuram district.
  • What makes the discovery special is that only two mature trees have been spotted so far in its natural habitat
  • The tree, which grows to a height of about six to nine metres with drooping branches, has been named Miliusa agasthyamalana after the location where it was found.
  • The identification of the new species has also taken the total number of species of Miliusa found in India to 25.
  • Spotted during a floristic survey in the Athirumala range of the Agasthyamala biosphere, the new species is morphologically similar to Miliusa paithalmalayana and Miliusa wightiana.
  • The researchers came across the new Miliusa species at elevations ranging between 1000-1250 metres.
  • Miliusa agasthyamalana has brown bark, and solitary flowers which are yellowish-pink in colour.

  • Flowering and fruiting occur during April-July.
  • Given the small number of mature individuals that have been found, researchers have recommended that the species be categorised as critically endangered (CR).
