Context – A plant discovered in Uttarakhand in 2019 has been newly confirmed as a new species of Allium
- A plant discovered in Uttarakhand in 2019 has been newly confirmed as a new species of Allium — the genus that includes many staple foods such as onion and garlic, among 1,100 species worldwide
- It grows at 3,000 to 4,800 m above sea level and can be found along open grassy meadows, sandy soils along rivers, and streams forming in snow pasture lands along alpine meadows, where the melting snow helps carry its seeds to more favourable areas.
- With a narrow distribution, this newly described species is restricted to the region of western Himalayas and hasn’t yet been reported from anywhere else in the world.
- The scientific name Allium negianum honours the late Dr Kuldeep Singh Negi, an explorer and Allium collector.
- Although new to science, this species has long been known under domestic cultivation to local communities. It said that according to locals, the onion from Niti valley was particularly good, even deemed the best on the market.
- So far only known from the western Himalaya region, Allium negianum might be under pressure from people looking to taste it. The researchers fear that indiscriminate harvest of its leaves and bulbs for seasoning may pose a threat to its wild populations.
