Posted on May 23, 2023

Finding
SITF has determined this plant to be Phragmipedium humboldtii, not P. wallisii (May 2023). Phragmipedium wallisii is now considered a synomym for P. warszewiczianum, however, this plant does not match the description of P. warszewiczianum; The flower color, plant habit, and staminode shape matches P. humboldtii, as seen in the IOSPE. The longer petal length also supports this as P. humboldtii. Lindleyana article (2011) by Dressler & Pupulin has photos for comparison and a key to P. humboldtii.
