» Note on the pronunciation of the genus Agave: The version given below (or something close to it) is just about the only one you’ll ever hear, whether you’re in the company of novices or experts. It’s a more-or-less Spanish pronunciation, which is not remarkable given the plants’ natural distribution. But the word in fact comes from the Greek agauos, meaning illustrious, and many sane and reliable older references give the pronuciation as uh-GAY-vee. Absolutely, I am not making this up. Of course, if you actually use that pronunciation in the presence of others, they’ll look at you as though you had three heads. Your choice.

» Note on the pronunciation of the genus Penstemon: The version given below gives penstemon people fits. Practically everyone says PEN-stih-mun. In this case, however, I simply can’t yield to popular practice. All the most reliable references insist on pen-STEE-mun, for the reason (clearly not convincing to the masses) that the -stemon part (which means “stamen” in Greek) is spelled with an eta, or long e. Personally, I find that wonderfully persuasive, and am willing to risk ridicule and ostracism in the name of principle. But you will do what you must.
