Relevance: GS III (Environment & Biodiversity)

A rare plant species, Agapetes wardii, has been recorded for the first time in India from Changlang district Arunachal, where it was earlier known only from Myanmar.

Key Highlights of the Discovery

• The species was identified by researchers from the Society for Education and Environmental Development.
• It is an epiphytic shrub, meaning it grows on other plants without harming them.
• Found in moist evergreen forests, often near water sources.

Botanical Features

• Tubular flowers ranging from red to pink (sometimes white).
• Elliptic to lanceolate leaves.
• Identification confirmed through morphological and taxonomic analysis, comparing with related species like:
• Agapetes hosseana, Agapetes mannii, Agapetes buxifolia

Why Arunachal Pradesh is Biodiversity-Rich

• Located in the Eastern Himalayan region, known for high species diversity.
• Features dense forests, varied altitude, and high rainfall, creating ideal conditions for plant growth.
• Hosts numerous species under the Agapetes genus, reflecting ecological richness.
