The plant was published as a new species for science, in 1998 in the BROMÉLIA MAGAZINE of Brazilian Bromeliad Society-SBBR, and was named by Till as Tillandsia barrosoae, in a well deserved tribute to its colector Graziela Maciel Barroso, already considered the most important botanist of South America. A few years later, in 2001, I would visit a portion of the area of occurrance of this plant, near Pirenópolis, in the state of Goiás, but it was a very fast passage. Returning from Mato Grosso state, in march 2018, I sensed that I would find them in flowers, which led me to divert my route a little to the region, hoping to make photographic records and to investigate the phytogeography of Serra dos Pirineus.
I couldn´t find them in flowers, as I thought I would, but of course I didn´t lose the opportunity to examine closely the habitat, taking notes about its state of conservation, together with some other observations on the flora of that mountain range, which is very unique. Tillandsia barrosoae is endemic to Serra dos Pirineus and has a very narrow area of occurrence even within those mountains, related to the Arco da Canastra–Brasília, a disjunction of the very extensive Cadeia do Espinhaço, a chain of quartzite mountains that crosses part of NE and SE Brazil.
