Tillandsia ionantha, the air plant (a common name shared by most species in its genus),[2] is a species of plant in the genus Tillandsia.

It is also reportedly naturalized in Broward County, Florida, United States.

[1][3][4][5] They are acaulescent or sometimes shortly caulescent plants, with a size of 6–8 cm high.

The leaves are 4–9 cm long; with pods 0.6–1 cm wide, densely patent fabric; narrow triangular sheets, 0.3–0.4 cm wide, dense lepidota indument, foliaceous bracts; compound inflorescence (of simple appearance due to the reduction of the spikes to 1 flower), with 1–3 flowers, primary foliaceous bracts, much longer than the spikes, floral bracts 3 cm long, longer than the sepals and covering them in the anthesis, ecarinated, inconspicuously nervate, glabrous, membranous, sessile flowers; sepals are 2 cm long, free, the posterior carinate, the anterior ecarinated; purple petals.

[6] Tillandsia ionantha was described by Jules Emile Planchon and published in Flore des Serres et des Jardins de l'Europe 10: 101, t. 1006.
