Botanists from multiple institutions have discovered three new endemic plant species in the Eastern Ghats of Andhra Pradesh: Euphorbia ananthapuramensis, Euphorbia chalamensis, and Ceropegia andhrica. Identified after extensive field surveys, each species exhibits restricted geographic ranges and extremely small populations containing fewer than 200 mature individuals. Due to severe immediate threats from anthropogenic activities including granite quarrying, livestock overgrazing, habitat fragmentation, and frequent forest fires, researchers have classified all three species as Critically Endangered under the International Union for Conservation of Nature (IUCN) Red List criteria. This discovery highlights the overlooked biodiversity value and urgent conservation requirements of the Eastern Ghats.
In May 2026, a team of field botanists published the discovery of three entirely new plant species found across the discontinuous hills of the Eastern Ghats in Andhra Pradesh. The species were named Euphorbia ananthapuramensis, Euphorbia chalamensis, and Ceropegia andhrica. They were confirmed as unique distinct species through thorough morphological evaluation and comparisons with global herbarium records. Because all three species occupy highly restricted ecological niches with critically small populations, they have been classified as Critically Endangered under the global IUCN Red List guidelines.
The discoveries were formally reported and cataloged in international botanical journals in May 2026 following five years of field explorations. The collection sites are located within three distinct districts of Andhra Pradesh. Euphorbia ananthapuramensis was discovered in the Nigidi Forest of Sri Sathya Sai district. Euphorbia chalamensis was found in the Chalama Forest within the Gundla Brahmeswaram Wildlife Sanctuary in Nandyal district. Ceropegia andhrica was collected from the high-altitude Paderu forest division in Alluri Sitharamaraju district.
The scientific breakthrough was led by Dr. Kothareddy Prasad from Delhi University, alongside Professor B. Ravi Prasad Rao of Sri Krishnadevaraya University (Anantapuramu) and Professor A. Madhusudhana Reddy of Yogi Vemana University (Kadapa). Tribal communities residing in these forest divisions act as crucial local stakeholders, possessing deep traditional knowledge regarding the medicinal and edible values of these plants. The duplicate physical specimens of these plants have been deposited at the Botanical Survey of India (BSI) repository in Kolkata for official archival documentation.
The identification process follows systematic taxonomic protocols:
This event holds massive ecological significance. It proves that despite centuries of human activity, the Eastern Ghats still harbor undocumented endemic wildlife. This relates directly to the UPSC Civil Services GS Paper 3 syllabus under Environment and Biodiversity. From an economic perspective, these plants carry useful biochemical properties. Culturally and socially, local indigenous tribes rely heavily on these plants. Ceropegia andhrica produces underground storage tubers that function as a traditional "famine food" during severe droughts.
The Eastern Ghats are a highly weathered, ancient geological chain that dates back to the breakup of the supercontinent Rodinia. Unlike the continuous, highly protected Western Ghats, the Eastern Ghats have historically received less scientific funding and conservation focus. Over the past decades, botanical efforts like those by the Botanical Survey of India (established in 1890) have slowly documented the region's flora. Past breakthroughs, such as finding Crinum andhricum in 2024 and Dicliptera srisailamica in late 2024, have steadily shown that this dry, rocky landscape holds a high degree of plant endemism.
Over the last few years, the Eastern Ghats have faced growing environmental stress alongside new botanical discoveries. In 2024, researchers discovered Crinum andhricum, a rare white-flowered plant growing in rocky crevices that was immediately threatened by forest fires. In early 2026, scientists discovered Cyphostemma annamalaii, a wild relative of the grape family, on Sanjeevi Hill in Tamil Nadu's southern Eastern Ghats. Concurrently, the 2024–2025 State of Forest Reports highlighted that scrub forests in Andhra Pradesh are facing severe fragmentation due to road expansions and clearing land for agriculture.
The discoveries directly connect to two major textbook concepts:
Globally, India is recognized as a megadiverse country under the Convention on Biological Diversity (CBD). While India protects its four designated global biodiversity hotspots (Himalaya, Western Ghats, Indo-Burma, and Sundaland), the Eastern Ghats lack this status. The Eastern Ghats feature lower rainfall and more broken terrain than tropical global hotspots like the Amazon or Western Ghats. However, their rates of plant endemism per square kilometer match those of many semi-arid global ecosystems, such as parts of the African Savannah or the dry scrublands of Australia.
If legal protections are not upgraded soon, these newly discovered plants face a high risk of extinction in the wild. Granite quarrying operations in the Sri Sathya Sai district could completely destroy the tiny habitat of Euphorbia ananthapuramensis. Frequent forest fires and overgrazing by livestock will likely shrink the populations of Euphorbia chalamensis and Ceropegia andhrica. To counter this, environmental agencies must work with local village councils to set up Community Reserves under the Wildlife Protection Act, ensuring these plants survive past 2030.
