A note on an edible fern of Nepal: Blechnum orientale L.

Abstract

Background: The consumption of ferns as vegetables and pickles in Nepal is a noteworthy phenomenon. Diplazium esculentum stands out as one of the most commonly consumed ferns. Being rich in plant resources, eastern Nepal remains relatively unexplored compared to central Nepal. Therefore, the present study seeks to provide a brief account of the edible uses of Blechnum orientale, a fern species, from eastern Nepal. Methods: Multiple field visits were conducted in Pathari Municipality and Kanepokhari Rural Municipality of Morang district. The habitats where B. orientale was collected by local vendors were examined, ethnobotanical uses, photographs, and market prices were recorded.Results: From April to May, young fronds of B. orientale were collected from local community forests by Tamang, Limbu, and Magar tribes of an area. Young fronds were washed, boiled to soften them, and used to prepare vegetables. Pickles are also made by mixing boiled young fronds with potatoes, green chili, onions, salt, mustard oil, and flax seed powder. Local vendors sell the fronds in bundles along Mahendra Highway in the price of 50 to 100 Nrs per bundle. Conclusion:The fern is a vital vegetable source for local communities during the monsoon season, providing sustenance and income generation opportunities. Sustainable collection and commercialization are recommended.
