Since I like to pick apart scientific names of plants, let’s look at the name of Spicebush (Lindera benzoin), whose fruits are just now ripening to red here in the mid-Atlantic. That benzoin is interesting; it suggests benzene. Do they have something in common? And which came first?

Well, it’s easy to figure out which came first, as Linnaeus named the plant in the 18th century, while Kekulé worked out the structure of benzene (the simplest aromatic hydrocarbon) in the 19th century, after Michael Faraday and others first isolated the chemical and named it earlier in the century. Benzene (benzin, benzol) was derived from benzoic acid, which in turn was derived from gum benzoin. Gum benzoin, known since antiquity, is an aromatic resin made from the bark of several species of trees in the genus Styrax.

So where did the word benzoin come from? Doesn’t sound very Latin. It’s traced back to Middle French benjoin, to Catalan benjuí, to Arabic لُبَان جَاوِيّ (lubān jāwiyy, “Javanese frankincense”).

And just to bring it back home, we have two native species of Styrax in Virginia, American Snowbell (S. americanus) and Bigleaf Snowbell (S. grandifolius). Both are found in the southern counties of the state.
