anhedral (allotriomorphic) A morphological term referring to grains in igneous rocks which have no regular crystalline shape. Anhedral forms are developed when a crystal's free growth in a melt is inhibited by the presence of surrounding crystals. The shape of the growing crystal is thus controlled by the arrangement and orientation of the surrounding pre-existing crystals. Compare EUHEDRAL.
