Name:From the language of the early inhabitants of the discovery area (Franklin, NJ), the Lenni Lenape Indians, "wawayanda", many or several windings, in allusion to the grossly curved and winding habit of the mineral's crystals.


Only a very few specimens of this chemically unusual species are known.
