when not flowering can hardly be distinguished from many other orchid species in the area, whereas it apparently rarely blossoms in nature. Formally, the species may tentatively be assessed as Vulnerable (VU) following the IUCN criterion D1, as the observed population contains surely less than 1000 mature individuals. However, additional field studies are necessary to comprehensively establish the status of the species.
