One of my favorites! Found in Central and Southern Mexico, this pendant growing species carries light green/gray leaves with a powdery appearance. The bloom is approximately 3 inches long with a sweet lemony scent. (Syn. Encyclia citrina; prosthechea citrina, Cattleya citrina) Does anyone know the difference between citrina and karwinskii? To me they look exactly the same some with a white lip and some without. IOSPE has them listed as two separate species, but doesn't give an explanation to the differences between them.
