History : More and more in collections of Phrag. hirtzii were plants found that were quite different from the type species in size and especially because of the pubescence of the staminode. Partly these plants came in circulation in the U.S.A. and Japan as being the true species. One of these plants was even under the name of Phrag. hirtzii 'Fox Valley' awarded an HCC by the AOS. This awarded plant was used by Olaf Gruß and Tom Kalina as type material for the description of the natural hybrid Phragmipedium hirtzii Dodson × Phragmipedium longifolium (Reichenbach fil. & Warszewicz) Rolfe.
Comments : This natural hybrid is quite variable in appearance. That is in size of the plant, the colouration of the flowers as well as in the amount of hairs on the staminode.
