New Ginger Species Discovered in Arunachal Pradesh’s Siang Valley

A new species of ginger, “Parakaempferia alba”, has been discovered in the Siang Valley of Arunachal Pradesh, reaffirming the Eastern Himalayas as one of the world’s most significant biodiversity hotspots. The discovery adds to India’s rich botanical record and highlights the ecological importance of the lesser-explored forest ecosystems of the region.

Discovery and Publication Details

The species has been formally described in the Nordic Journal of Botany, lending global scientific recognition to the finding. The research was carried out by a team comprising Tatum Mibang, Bipankar Hajong, Devpratim Koch, and Pankaj Bharali. Scientists involved emphasised that such discoveries underline the need for sustained botanical exploration in the Eastern Himalayas.

Habitat and Ecological Setting

“Parakaempferia alba” was located in the Miglung area of East Siang district in the Arunachal Pradesh. The plant grows at altitudes ranging between 150 and 400 metres. It thrives along shaded streambanks with humid conditions and sandy soil, indicating its preference for fragile microhabitats closely linked to forest and freshwater ecosystems.

Taxonomy and Scientific Significance

The newly identified species belongs to the ginger family, Zingiberaceae, a plant group known for its culinary, medicinal and economic value. Researchers note that the discovery not only expands the known diversity of the genus “Parakaempferia” but also strengthens evidence that the Siang Valley region harbours many undocumented plant species.

Imporatnt Facts for Exams

• “Parakaempferia alba” is a newly discovered species from the ginger family Zingiberaceae.
• The species was found in the Siang Valley of Arunachal Pradesh.
• The Eastern Himalayas are recognised as a global biodiversity hotspot.
• Botanical discoveries aid conservation planning and ecological assessment.

Potential Uses and Conservation Relevance

Scientists suggest that “Parakaempferia alba” may hold medicinal or economic potential, although detailed phytochemical and applied research is still required. The discovery also underscores the importance of conserving forested streamside habitats, which are increasingly vulnerable to land-use change and climate stress in the Eastern Himalayan region.
