I have only seen it spelled "stroggylos" or "strongylos", but I don't know much Greek.

Can't see what is so stupid with your question, the pronunciation of regular Latin words is far from obvious, and it does not become easier when the words are Latinized forms of geographical names in other languages. In my book about plant names emphasis is on the second 'o' in Copiapoa. Sadly, bota...
