Well, you all make me feel a lot better. When I found out the correct pronunciation, I posted it somewhere, probably the Clematis cubit, and Evey and everyone else said they always pronounce it FEWK-see-ya and acted surprised that I didn't know. (I bet they didn't know either and were just being condescending.)
So, tell me, how do you pronounce clematis? CLE-ma-tis, cle-MAT-is, or cle-MAHT-is? I use the second pronunciation.
