Olsynium:  a name applied by C.S. Rafinesque who "explained Olsynium as "hardly united" referring to the stamens. He didn't explain what Greek root he used to indicate 'hardly,'" (from David Hollombe). The Dictionary of Word Roots gives the meaning of the Greek prefix ol- as "whole or entire." The Greek prefix syn- means "together," and the prefix -ium usually means something like "characteristic of" (contributed by Cynthia Powell)
