SITF confirms this plant as Phragmipedium warszewiczianum (Jul 2025). This plant matches the species. The subspecies var. wallisii is an old remnant from splitting the P. caudatum group, and used to be P. caudatum var wallisii. The variety wallisii is now considered by Kew POWO to be synonymous with the species. The correct name is simply Phragmipedium warszewiczianum.
