Remarks:
Phragmipedium grande is a natural hybrid of Phragmipedium longifolium and Phragmipedium warscewiczianum. According to O. Gruß 2013, due to the priority rule, the valid name would be Phragmipedium × pfitzerianum O.Gruss 2013.
The correct spelling for plants found in nature would be Phragmipedium X grande, if the plants come from artificial (horticultural) propagation Phragmipedium Grande or Phragmipedium X Grande is correct.
Phragmipedium grande = Phragmipedium caudatum x Phragmipedium longifolium (cannot be a natural hybrid, too many km between them)
Phragmipedium pfitzerianaum = (Phragmipedium warscewiczianum x Phragmipedium longifolium) Natural hybrid from Ecuador possible.
