荷属东印度群岛的猪笼草科植物
B. H. Danser treated "N. edwardsiana" in synonymy with "N. villosa" in his seminal monograph, "The Nepenthaceae of the Netherlands Indies", published in 1928. The work included a revised Latin diagnosis and botanical description of "N. villosa". Eight years later, Hermann Harms once again elevated "N. edwardsiana" to species status. This treatment was supported by Shigeo Kurata in 1976 and has not been challenged since.
