Susan, so glad you asked!!! If you look on the right side box, there's an Abbreviations link. Just hit the O on top and you'll have your answer! I looked briefly and saw two species. Then you can look up the culture for each in the AOS Culture Sheets link (also on the right) and aim for the middle if they have different needs. If you can't figure out what alliance (family) an orchid fits into (so you can chose a culture sheet to read), the Pages link on the right has classifications and this may help. Todd worked on this Alliance page with me, but these are slippery since the taxonomists keep changing it around (and their genera)! Please feel free to ask more questions. As you can tell, all this info was set up for folks who ask your very question!! And that's why I'm glad you asked!
