Abstract:—Based on morphological evidence, we propose to raise Tillandsia mauryana forma secundifolia to species level with the name Viridantha secundifolia (Ehlers) Hern.-Cárdenas, Espejo & López-Ferr. Viridantha secundifolia can be readily distinguished by the falciform rosettes, the broadly oblong to square, 1–1.2 × 0.8–1.1 cm leaf sheaths and by the 1.8–2 × 0.7–1.2 cm floral bracts. Additionally, we describe and illustrate Viridantha uniflora Hern.-Cárdenas, Espejo & López-Ferr., from the state of Oaxaca, Mexico. The new species is morphologically similar to Viridantha boqueronensis, but differs by the nearly square leaf sheaths, 1.3–1.5 × 0.4– 0.5 cm spikes and by the presence of only one flower per spike. A key to the taxa, morphological descriptions, list of specimens examined, illustrations and a distribution map of the described taxa are included.
