New plant species Osbeckia assamensis discovered in Manas National Park

Researchers have identified a new flowering plant species, Osbeckia assamensis, in Assam’s Manas National Park. The perennial shrub, which belongs to the Melastomataceae family, was documented following field surveys conducted between 2021 and 2025.

The discovery was detailed in a study by Professor Namita Nath of Gauhati University and Barnali Das, an assistant professor from Pragjyotish College. Their findings, which include taxonomic descriptions and photographic illustrations, were published in the botanical journal Phytotaxa on October 22.

Osbeckia assamensis is morphologically similar to Osbeckia nayarii but is distinguished by its branching pattern, stem characteristics, foliar features, and inflorescence containing 30-35 flowers. Assam Chief Minister Himanta Biswa Sarma and State Environment and Forest Minister Jayanta Mallabaruah noted that the discovery highlights the region’s significant floral diversity and the ongoing importance of nature conservation efforts in the state.
