The names above are derived from the Latin and Greek languages and can, at first, be daunting to pronounce. It's easier if you remember that, with few exceptions all letters are pronounced. You will often hear names pronounced somewhat differently than indicated as a result of regional differences. There are also pronunciations that are not technically correct but have found their way into common usage. The common pronunciation, stan-HOPE-ee-ah rather than the technically correct stan-HOPE-ah for Stanhopea is an example. This pronunciation has no doubt evolved because of the "pronounce every letter rule" although that would sound more like stan-HOPE-AY-ah.
