Plectrophora-calcarhamata-Irene-CHM/AOS-2019-09-17***Determined to be Plectrophora cf. cultrifolia, not P. calcarhamata (Mar 2021); P. calcarhamata is an equitant leaved plant with no discernable pseudobulbs; this plant has ancipitous (flattened with two edges) pseudobulbs; P. cultrifolia is named for its knife blade-shaped leaf and pseudobulb which is a good match with this plant;  the flower size and more open form also favor P. cultrifolia; since the plant is larger and the leaves somewhat longer than P. cultrifolia, there is some uncertainty in the identification, so it is qualified as Plectrophora cf. cultrifolia as the best fit for this plant.***
