scalenohedron A crystal form consisting of a number (usually 6 or 12) of triangular faces, all with unequal sides. Its crystal symmetry is either tetragonal or, more frequently, hexagonal. Each face cuts the vertical c (or z) axis and the form is often developed in the mineral calcite, where it is called ‘dog-tooth spar’.
