New Orchid Discovery in Sikkim: Gastrodia indica, the Orchid That Never Blooms

A recently discovered orchid species, Gastrodia indica, found in the Fambonglho Wildlife Sanctuary, Sikkim, presents a unique case in the world of botany. This orchid challenges the typical characteristics of blooming orchids as it never opens its flowers. The discovery was made by botanist Madhusudan Khanal from the G.B. Pant National Institute of Himalayan Environment—Sikkim Regional Centre.
