Phragmipedium-wallisii-2023-05-23 *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.

CHALLENGE-to-Phragmipedium-longifolium-var-longifolium-(Album)-2022-09-23***SITF confirmed as Phragmipedium longifolium var. longifolium (Sep 2022);
This plant matches the album form of P. longifolium var. longifolium; the challenge was issued based on undulations of the petal margins; however nearly all P. longifoliums have undulations of the petal margins to varying extents and, therefore, are not contraindicative of this plant being the correct species;  one of the photos of this plant show auricles raised above the pouch tissue which is a characteristic of the species; this plant closely matches the P. longifolium f. album in Guido Braem's book, "The Genus Phragmipedium".***

Phragmipedium-schlimii-var-manzurii-2020-02-23***Confirmed as Phragmipedium schlimii (July 2020); the origin of the plant or its parentage is unknown; this is essential to know whether it might be f. albiflorum or var. manzurii or other.  Morphologically, it resembles forma albiflorum more than manzurii; however, unless it came from two authenticated forma albiflorum parents, it should remain at the species level.***
