This species is from Ecuador is very much grows like Tillandsia cyanea, but is a larger plant. It produces a taller inflorescence, on a longer scape, and large violet flowers.
Previously known as Tillandsia lindenii it was moved to the genus Wallisia and determined to be Wallisia x duvalii. When a species name includes an "x" before it, that indicates that it is a natural hybrid. This appears to be a hybrid of Wallisia cyanea and W. lindeniana.
