Named by P.J. Dunn and R.S. Rouse in 1979 after Nils Gustaf Sundius (21 May 1886, Banker, Östergötland, Sweden - 6 December 1976, Djursholm, Danderyd, Stockholm County, Sweden), mineralogist with the Geological Survey of Sweden, in recognition of his contributions to the mineralogy of Långban (Sweden). Pronounced sūn'-dē-ūs-ite.
The name was used previously for a hypothetical amphibole, but its use not widely recognized.
