1902 H. A. Miers Mineral. i. 45 When an axis of n-fold symmetry is perpendicular to n digonal axes and there is no other element of symmetry, the crystal may be called ‘holoaxial’, since it possesses all the symmetry-axes compatible with each other, and only axes.

1903 H. Hilton Math. Crystallogr. v. 52 In this chapter we shall investigate those finite groups of the first sort—also called holoaxial groups—which contain only 2-al, 3-al, 4-al, and 6-al rotation-axes.

1961 P. Terpstra & L. W. Codd Crystallometry iv. 129 Crystals are divided according to their true symmetry into 32 crystal classes. Of these 32 classes, 11 have symmetry elements consisting exclusively of symmetry axes: these are called the eleven holoaxial classes.
