FAST READ
- Researchers documented Ophiopogon japonicus in Arunachal Pradesh's West Kameng district, reported as the first confirmed wild record of the species in India.
- The specimen was collected at about 2,185 m elevation in a moist, shaded temperate broadleaf-forest habitat.
- The finding extends the known distribution of an East Asian species into the Eastern Himalaya and highlights the value of field taxonomy.
WHY IN NEWS
- The 2026 record adds a species to India's documented flora and underlines how under-surveyed Himalayan habitats can still yield important distributional discoveries.
- Its roadside habitat is exposed to landslides and construction, making follow-up surveys relevant for conservation assessment.
TOP DATA & FACTS
- The species is Ophiopogon japonicus (Thunb.) Ker Gawl.
- It belongs to the family Asparagaceae under modern APG classification.
- The common names include dwarf lilyturf and mondo grass.
- The Indian record is from West Kameng district, Arunachal Pradesh.
- The documented elevation is about 2,185 m.
- The specimen was collected during a floristic survey in May 2025.
- Its wider native range includes China, Japan, Korea and Nepal.
- The species is commonly reported across approximately 200-2,800 m elevation in its broader range.
- Seven other Ophiopogon species had already been recorded from India according to the current-affairs report.
- An 1830s Kumaon specimen associated with Wallich's catalogue had not been taxonomically confirmed as this species.
- The plant has grass-like leaves.
- It bears blue to bluish berry-like fruits.
- Its tuberous roots are known in East Asian traditional medicine as Maidong or Ophiopogonis Radix.
- The 2026 record was reported from a moist shaded forest floor near the Shergaon-Gyuto monastery road.
- Road construction and landslide disturbance were identified as local conservation concerns.
PRELIMS
- Ophiopogon japonicus belongs to Asparagaceae.
- West Kameng is in Arunachal Pradesh in the Eastern Himalaya.
- A first country record means a species is newly confirmed from that country's flora; it does not mean the species evolved there recently.
- A range extension can result from new survey effort, taxonomic revision or genuine movement.
- Herbarium vouchers are important for reproducible taxonomic identification.
