Irph and Charm, I'd like to introduce you to a terrific orchid reference that I use all the time to look up orchid species - It's Internet Orchid Species Photo Encyclopedia or as we affectionately call it - Jay's -
Internet Orchid Species Photo Encyclopedia
All you have to do is either chose from the alphabetical list for an orchid species or type in the name in the search and waaah laaa .. you get the orchid of your choice and it's explanation and culture ..
I looked up Mediocalcar decoratum to see the flowers close up and lo and behold it came up as little candy corn colored puffer fish shaped beauties -

I use Jay's constantly and hope it will be a useful tool for the both of you
Cheers!
