A new orchid species has been discovered in Kanthalloor and Marayoor in Kerala’s Idukki district. The plant belongs to the Diplozentrum genus, which is restricted to the southern ranges of the Western Ghats. It has been scientifically named Diplozentrum papillosum. The species stands out for its flower structure, fragrance and habitat adaptation.
Discovery and Scientific Naming
The orchid was identified by a research team led by Dr Jose Mathew, along with A K Pradeep, Mathew Jose Mathew and Salim Pichan. The species name papillosum reflects its distinct floral features. The finding has been brought into light as the cover story in the latest issue of the scientific journal Species.
Distinctive Botanical Features
- The orchid grows on rocks and tree branches.
- It has strong roots that help it resist strong winds.
- Its flower clusters are unbranched.
- The blooms are pink and white in colour.
- The petals have a unique shape that differentiates it from other species in the genus.
- The flowers are both fragrant and visually striking.
Significance of the Find
The discovery adds to the botanical diversity known from the Western Ghats, one of India’s richest biodiversity hotspots. Species in the Diplozentrum genus are found only in the southern Western Ghats, making this find important for plant taxonomy and conservation studies. It also underlines the ecological value of the highland habitats of Idukki.
Western Ghats Biodiversity Context
The Western Ghats support a large number of endemic plant species. New discoveries from this region help scientists understand species evolution, habitat specialisation and conservation needs. Orchids are often used as indicators of ecological health because they are sensitive to habitat change.
