SITF has determined this plant to be Laelia colombiana (Jul 2024), not Schomburgkia rosea. Schomburgkia rosea is synonymous with Laelia rosea after the Genus Schomburgkia was split into two genera. Laelia wallisii is also synonymous with L. colombiana, the accepted name by Kew. Both L. undulata and L. colombiana have three keels as shown in the photos, but those of L. undulata are much longer and the lip doesn't reflex as sharply as L. colombiana. his plant also best matches the photos of L. colombiana (as L. wallisii). This plant looks identical to Schomburgkia wallisii (synonym) in the IOSPE.
