Notes	The symbol '?' designates a species with taxonomic conflicts within the genus Phragmipedium.

Taxonomic Conflicts within Phragmipedium
• ecuadorense - considered a species by RHS. Considered a variety of pearcei by Cash 1991. Considered a synonym of pearcei by McCook 1999. If true, then Ecua-Bess and Olaf Gruss are the same RHS grex.
• sargentianum - considered a species by RHS. Supported as a species by Cash 1991. Considered a synonym of lindleyanum by McCook 1999. If true, then Andean Fire and Memoria Dick Clements are the same RHS grex.
• kaieteurum - considered a species by RHS. Considered a variety of lindleyanum by Cash 1991. Considered a synonym of lindleyanum by McCook 1999. If true, then Andean Fire and Rosalie Dixler are the same RHS grex.
• richteri - considered a species by RHS. Not listed by Cash 1991. Considered a natural hybrid of pearcei x boissierianum by McCook 1999. If true, then the RHS grex notation for Franz Glanz must be amended. Oddly, there is no RHS grex for a cross between pearcei x boissierianum. If they are natural hybrids, why haven't they been artifically crossed and registered?
• hirtzii - considered a species by RHS. Not listed by Cash 1991. Supported as a species by McCook 1999.
• czerwiakowianum - considered a species by RHS. Considered a variety of boissierianum by Cash 1991. Considered a synonym of boissierianum by McCook 1999. If true, then Lutz Röllke and Robert Palm are the same RHS grex.
• fischeri - considered a species by RHS. Not listed by Cash 1991. Considered a synonym of schlimii by McCook 1999. If true, then Hanne Popow and Barbara LeAnn are the same RHS grex.
• warscewiczianum - considered a species by RHS. Supported as a species by Cash 1991. Considered a synonym of caudatum by McCook 1999. If true, then Ruby Slippers and Super Rubies are the same RHS grex.
• lindenii - considered a species by RHS. Supported as a species by Cash 1991 and McCook 1999.
  • This species is a slipper orchid without a slipper. Perhaps peloric and certainly self pollinating. A truly odd species. RHS grex registration lists only two historical entries, Phragmipedium Macrochilum 1891 (lindenii x longifolium) and Phragmipedium Clonius 1893 (lindenii x Conchiferum [ = longifolium x caricinum] ).
  • Species lindenii has not yet been crossed with besseae.
• exstaminodium - considered a species by RHS. Not listed by Cash 1991. Supported as a species by McCook 1999.
  • Species exstaminodium has not yet been crossed with besseae.
• xerophyticum - not registered by RHS. Not listed by Cash 1991. Proposed as a species by McCook 1999.
  • Species xerophyticum has not yet been crossed with besseae.
