Although only recognised as a distinct species towards the end of the 20th century, N. talangensis was collected as early as 1918 by H. A. B. Bünnemeijer. Bünnemeijer made three collections from Mount Talang during this time. The specimen series Bünnemeijer 5398 was collected on November 2, 1918, at an elevation of 2200 m. It is deposited at both Herbarium Bogoriense (BO), the herbarium of the Bogor Botanical Gardens, and the National Herbarium of the Netherlands (L) in Leiden (formerly Herbarium Lugduno-Batavum, the State Herbarium at Leiden), with all specimens lacking floral material. Bünnemeijer also collected Bünnemeijer 5397 on the same day at an elevation of 2400 m. It is deposited at Herbarium Bogoriense and lacks floral material.
