Guwahati: After more than two centuries, a rare flowering shrub, Ardisia colorata, has been rediscovered in Assam’s Bongaigaon district.Researchers Manash Baruah and Nilakshee Devi of Gauhati University’s botany department found the plant in Abhayapuri during botanical surveys conducted across Assam between 2020 and 2025. The surveys were part of an ongoing taxonomic study of the Ardisia genus.The researchers initially identified the specimen as Ardisia solanacea Roxb. However, a detailed study of its physical features and scientific literature revealed key differences.“In 1824, William Roxburgh also applied the same name to a different plant. This created considerable taxonomic confusion. However, further investigation indicated that the specimen corresponds more closely to Ardisia colorata G Lodd,” said Baruah.George Loddiges first described the species Ardisia colorata G. Lodd. in 1821. He based the description on plant material brought from India through networks of plant collectors and horticultural exchanges.“In his original description, Loddiges mentioned that the species was collected around 1816 and subsequently introduced into cultivation in Europe. These collectors travelled through forests, hills and remote regions, gathering plant specimens and sending them to Europe. As part of this process, this particular plant was also collected in 1816 and later preserved and observed at Loddiges’ nursery,” Baruah said.The identification was confirmed through an analysis of differences in the plant’s flowers, leaves, stem structure and size compared to other similar species.Assam forest and environment minister Jayanta Mallabaruah praised the researchers on ‘X’.“These findings also remind us that conservation extends far beyond our iconic rhinos, tigers and elephants. Even the smallest and least-known species have a place in Assam’s ecological heritage. My appreciation to the researchers and scientists whose patient work continues to uncover the extraordinary biodiversity of our state,” he added.
