Terminology
Acicular: Acicular, in mineralogy, refers to a crystal habit composed of slender, needle-like crystals.
Multi-terminated: Multi-termination refers to a habit in which a columnar hexagonal crystal is terminated by multiple needle-like elements, which are often serrated. This is neither an <i>official</i> term, nor is the Vorobyevite Museum hung up on it, but you have to call it something.
