anˈhedron n. a crystal of this kind.

ΚΠ

1896 L. V. Pirsson in Amer. Geologist XVII. 94 Since the term crystal, when strictly used, means a body possessing not only a certain internal molecular structure, with definite physical properties, but more especially an outward symmetrical form with plane faces, it is evident that there is no good term for the rounded or formless masses in which minerals occur in rocks. Therefore, after consultation with Prof. E. S. Dana, the term anhedron (meaning without planes) is proposed for these formless masses which possess the internal structure of crystals; and such minerals may also be spoken of as having an anhedral development.
