Treated as a synonym of Tillandsia crocata (E.Morr.) Baker
Tillandsia mandonii was based on very old and weathered material. The only character in its description to distinguish it from T. crocata is the supposedly glabrous sepals but both Mandon and Miers collections show some scales still left on the sepals. —SeeSmith 1935p. 182
