Botanists from the Wildlife Institute of India (WII), Dehradun, and the Uluberia Botanical Institute Herbarium documented the plant species Ophiopogon japonicus in the wild in India for the first time.
- The species was recorded at an elevation of 2,185 meters in a moist, temperate broadleaf forest floor in the West Kameng district of Arunachal Pradesh (Eastern Himalayas).
- Common Names - Dwarf Lilyturf, Mondo Grass, or Fountain Plant.
- Taxonomic Classification
- Family- Asparagaceae (subfamily Nolinoideae; historically placed under Liliaceae).
- Genus -The genus Ophiopogon comprises roughly 85 species worldwide; with this discovery, the number of species formally documented from India increases from 7 to 8.
- Morphological Features
- An evergreen, clumping perennial herb with narrow, arching, grass-like leaves (15–30 cm long) featuring backwardly serrated (retro-serrulate) margins.
- Produces short racemes of small white-to-pale-purple flowers that mature into metallic, bright cobalt-blue berry-like fleshy seeds.
- Spreads via subterranean stolons and slender rhizomes with swollen, water-storing tuberous roots.
- Geographic Distribution -Native across East Asia (China, Japan, Korea, and Nepal), thriving across a wide altitudinal range of 200–2,800 meters.
Medicinal Value
- Traditional East Asian Medicine - The dried tuberous roots are known as Ophiopogonis Radix or Maidong in Traditional Chinese Medicine (TCM).
- Bioactive Properties- Rich in bioactive polysaccharides, saponins, and flavonoids.
- Therapeutic Applications- Exhibited anti-inflammatory, antioxidant, immunomodulatory, and cardioprotective properties; clinically used to treat chronic dry coughs, protect mucosal barriers, and support cardiovascular health.
Conservation Significance
- Soil Conservation- Its fibrous, stoloniferous root matrix effectively binds loose topsoil on steep Himalayan slopes, mitigating soil erosion and landslides from heavy monsoon runoff.
- Biodiversity Benchmar- Extends the known geographic distribution of East Asian flora into the Eastern Himalayas, highlighting the region as a critical, under-explored botanical hotspot.
- Local Vulnerability- The newly recorded population faces localized anthropogenic threats due to its proximity to roadside habitats vulnerable to highway construction, slope degradation, and habitat fragmentation.
