hemihedral
CIDE DICTIONARY
hemihedral, a. [Hemi- + Gr. seat, base, fr. to sit.].
Having half of the similar parts of a crystals, instead of all; consisting of half the planes which full symmetry would require, as when a cube has planes only on half of its eight solid angles, or one plane out of a pair on each of its edges; or as in the case of a tetrahedron, which is hemihedral to an octahedron, it being contained under four of the planes of an octahedron. [1913 Webster]
OXFORD DICTIONARY
hemihedral, adj. Crystallog. having half the number of planes required for symmetry of the holohedral form.
