Origin of synonymy

1600–10; < Late Latin synōnymia < Greek synōnymía. See synonymous, -y³

The variety, as the synonymy shows, has been grown under many names both in America and Europe.

The Cherries of New York |U. P. Hedrick
The synonymy, as might be expected (for Seba was unknown to Linnus when the descriptions were written), was not in the original.

The Journal of the Proceedings of the Linnean Society - Vol. 4 |Various
This being a decisive specific character the synonymy prior to Rostafinski is somewhat uncertain.

The North American Slime-Moulds |Thomas H. (Thomas Huston) MacBride
The species are very variously understood by European botanists, and are much confused, as well as the synonymy.

The Manual of the Botany of the Northern United States |Asa Gray

The synonymy of Rostafinski is largely that of Fries, and upon this the Polish author attempts to apply the law of priority.

The North American Slime-Moulds |Thomas H. (Thomas Huston) MacBride
