[Botany • 2022] Tillandsia ertonii & T. nathanii (Bromeliaceae: Tillandsioideae) • Two New Species from Brazil


Tillandsia ertonii  E.H.Souza & Leme,
Tillandsia nathanii E.H.Souza & Leme,

in de Souza, Cavalcante, França, Aona, Souza et Leme, 2022. 
The authors describe, discuss, and illustrate two new species of Tillandsia from a granitic outcrop in the municipality of Petrópolis, Rio de Janeiro state, and from an inselberg located in the municipality of Belo Jardim, Pernambuco state, Brazil. The species are endemic with a restricted area of distribution, being considered critically endangered (CR) mainly due to habitat fragmentation and illegal extractivism, specifically for regional and international trade. We also present the phenology, a distribution map of the species, and compare them with morphologically similar taxa.
