Tillandsia bernalensis Hern.-Cárdenas, Espejo, López-Ferr. & L. Hern., sp. nov.
The new species is similar to Tillandsia parryi but differs in the width of the leaf blades (6–7 × vs. 3.5–3.7 cm in Tillandsia parryi), in the
rachis exposure in mature spikes (not exposed vs. exposed), in the color of the floral bracts (bicolored, vinaceous at the apex, green at
the base vs. unicolored, red to orange), in the floral bracts form and keel (obovate to oblong, ecarinate vs. elliptic to narrowly elliptic,
carinate at the apex), and in the width of the sepals (1.1–1.3 vs. 0.75–1 cm).
Etymology:— Specific epithet refers to the porphyritic monolith Peña de Bernal, on whose cliffs the new species grows.
