In News:

Researchers have confirmed the discovery of a new flowering plant species named Uniyalakeralensis (family: Asteraceae) in the Agasthyamala Biosphere Reserve (ABR), located in the southern Western Ghats of Kerala. Endemic to southwest India, the species is named in honour of the state of Kerala.

Key Features:

  • Plant Type: Dense shrub with light purple flowers, growing 1–3 metres tall.
  • Distinctive Traits: Larger leaves, longer petioles (leaf stalks), and fewer lateral veins compared to related species like U. comorinensis and U. salviifolia.
  • Flowering & Fruiting Period: August to April.
  • Habitat: Open areas on western mountain slopes of ABR, at elevations between 700–1,400 metres.
  • Distribution: Around 5,000 individuals across four subpopulations, covering an estimated area of 250 km².
  • IUCN Status (2024): Data Deficient (DD) due to limited information on long-term population trends.

The plant was first collected in 1998 and initially misidentified as Vernonia multibracteata. Later taxonomic revisions led to the recognition of Uniyala as a separate genus, named after botanist B.P. Uniyal, with this species formally described as new.
